ALDRICH No. 1444 CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION PRESS OF THE NEW ERA PRINTING COMPANY. LANCASTER. PA. \vv A CATALOGUE OF NORTH AMERICAN DIPTERA BY T. M. ALDRICH. INTRODUCTION. The present work is based upon Osten Sacken's Catalogue of North America Diptera, second edition, published in iS/S.* All the references of that work are embodied in this, with only such changes as later studies seem to require. Still, the great amount of work which has been done on North American Diptera within the quarter of a century has largely changed the face of the subject. Hence the reader will probably observe, especially at first, more of contrast than resemblance. The number of species has doubled ; the number of references to previously known species has almost doubled ; several families have been monographed or revised, with more or less change of nomenclature ; along with this has gone the publication of a multitude of smaller papers, touching every family but one, and the larger part of the genera. Under these conditions it is inevitable that great changes should appear in the new catalogue. It is the more necessary that I should acknowledge my obligation, which is far greater than appears on the surface. Faunal limits. These, as in the former catalogue, include all of North America, in the widest sense, taking in Panama on the South and Greenland and the Aleutian Islands on the North. The West Indies are included, even down to Trinidad, adjoining Venezuela. There is no place to draw a line between the islands. The Bermudas and the Hawaiian Islands are not included. Scope. To give the most information consistent with the limits of space has been the object. All references to a species, if in any way descriptive or useful, have been inserted if found. The only known exceptions are in those species like the Hessian fly and house- fly, where the references are so numerous that a selection of the more important articles is necessary. Another exception is uniformly made of articles in non-scientific journals ; these are only mentioned when of importance in tracing the history of a species. * Smithsonian Miscellaneous Collections, Vol. xvi. 2 CATALOGUE OF NORTH AMERICAN DIPTERA. Articles on biology and anatomy have been especially sought for. However it may be in other orders, the vast economic importance of the Diptera will not allow us to study the cabinet specimen only. In economic literature some of the minor references have been omitted, where no new facts appeared to be brought out. Every one knows that a considerable part of economic literature is of this class, and it is properly so, being prepared for a public who do not read entomological journals. The omitted articles are generally very brief ones, and strictly " popular " in form. There are some European writings on the biology of species occur- ring both in Europe and North America, which are not included. It was not deemed feasible to enter in detail into the European literature. Method. In form I have followed Osten Sacken quite closely. Few explanations will be needed. It is to be understood that the species is described with more or less fullness under each reference, unless an explanation is given indicating something else (as " oc." for occurrence; " syn." for synonymy; "notes," etc.). Still, I am aware that there are some cases where I failed to note the limitation. The locality is given with each reference. This is of importance in two ways. First, in furnishing the type locality, as closely as given by the describer ; second, in case a certain reference proves to have been due to an erroneous identification, it enables the reader to deduct that one and leave the rest unaffected. Every entomologist who acquires any familiarity with the literature of a group comes to trust some writers much more fully than others. It is only by separating the localities in the bibliography that these allowances can be made, with- out looking tip all the literature. Synonymy and nomenclature. Those synonyms which had been made out by Osten Sacken I have accepted in toto. More recently, a considerable number have been made out by the examination of types of Walker, Bigot, and others. These appear to be well-founded. In addition to these, a large number have been made out from descrip- tions, nearly every dipterist of the country having contributed some- thing in this direction. I have generally quoted these, although we may expect that some will ultimately prove erroneous. In a few cases I have expressed doubt, or an adverse opinion. The authority for synonymy is generally given in brackets, unless expressed in the context. In the selection of names, priority is accepted as the first test ; it may, however, be overshadowed by uncertainty as to the application of the older name. I have found comparatively few cases of specific names that were hard to decide, but among genera there are many which may be argued about as well one way as the other. I began with the intention of being very conservative ; but I have been drawn CATALOGUE OF NORTH AMERICAN DIPTERA. 3 along, inch by inch, until I am aware of having adopted most of the changes which I at first opposed. In this I have been influenced by the feeling that my catalogue must represent the actual condition of the classification, not merely my own views. Within a family or two, I would insist on the latter ; otherwise it has seemed best to con- cede something to the opinions of others, only interposing a check when some too revolutionary change is attempted (as in altering the name of Rhamphomyia) . I am far from believing that the changes of generic names now becoming common are in the interest of, or will attain, subsequent permanence. Such a hope is illusive. There will always be loop-holes which will allow further change. We are as near to permanence now as we ever shall be. System. The sequence of families is substantially that of Osten Sacken's later papers, influenced in minor points by Coquillett. Brauer's system, although finding some favor in Europe at present, appears less expressive of the relations. An abstract of the classifica- tion will be found at the end of the introduction. Acknowledgments. First of all, I am indebted to Baron Osten Sacken for his catalogue, the basis of my work. It is the best designed, most accurate, most informing work of the kind that I have ever seen, on any large order or group of animals. Hence it has been a great ad- vantage to me to have such a guide to follow. While I do not claim any such command of the subject as was possessed by Osten Sacken, I am sure that my work has been benefited by the influence of his. I also acknowledge the receipt of frequent encouraging and inspiring letters from him during the progress of my work. He is not, however, responsible for any of the details of my classification. To Professor S. W. Williston I am deeply indebted. His encour- agement first induced me to undertake the preparation of this Cata- logue. He gave me many unpublished notes, and looked over the manuscript of the Asilidse. His published bibliographies I found in- dispensable. In this connection I will add that his disinterested labors in the cause during a long series of years, amid the arduous and exact- ing duties of his more immediate specialties, call for our admiration and our gratitude. These labors, considering also his success in adapt- ing his writings to the needs of beginners in the science, entitle him to rank with Osten Sacken as one of the founders of North American dipterology. Mr. D. W. Coquillett several times furnished me with information on obscure references, always responding promptly and courteously with just what I wanted. Dr. L. O. Howard gave me a number of practical suggestions which influenced the form of my work somewhat ; he also assisted me very materially in getting it printed, and was, as usual, continually giving me unexpected but gratefully appreciated lifts. 4 CATALOGUE OF NORTH AMERICAN DIPTERA. Professor J. H. Comstock extended courtesies when I was visiting Cornell. In his department I examined a considerable collection of Diptera determined by Osten Sacken and \Yilliston, also some inter- esting literature. In the Cornell University library I found " Silli- man's Journal." Mr. Samuel Henshaw assisted me very kindly when I examined some families in the Loew-Osten Sacken collection at Harvard Uni- versity. Dr. Garry de N. Hough gave me some unpublished notes, and a large number of Diptera. Mr. O. A. Johannsen, of Cornell University, revised the classifica- tion of the Chironomidae for me, greatly improving my work on that family. Mr. Hugo Kahl gave me unpublished notes of his own ; he also gave me minute directions about some points to look up in the Loew- Osten Sacken collection, the outcome of which gave me a very high opinion of Mr. Kahl's acuteness in systematic work, and revealed some peculiar errors of Loew in describing two or three species. To W. D. Hunter, C. W. Johnson, C. T. Brues, and Professors V. L. Kellogg and C. V. Piper, I am indebted for references to literature. Mr. A. L. Melander gave me great assistance in the Empididse. I have followed his advice quite uniformly in regard to nomenclature and synonymy in that family. I have availed myself of Dr. Coloman Kertesz's great work, " Cata- logus Dipterorum," of which two volumes have reached me, only to the extent of adopting the generic distribution of the Cecidomyidae, and of picking up one species Cnle.v penafieli Will. which I had not found before. My work was almost completed when the first volume of Kertesz came out. To all the gentlemen named, I extend my sincere thanks. The catalogue closes January I, 1904. J. M. ALDRICH.

I have seen no correct colla- tion. Sometimes his Roman numerals stop and remain the same for several papers, then again the numbering in " parts " becomes stationary while the other goes on, and in two cases two papers have both the same (xxxvn, part 29, and XLII, part 34). In the Bulletin the confusion is worse confounded. This publication appears to have been for some time regularly published in two forms, one numbered in Arabic, and the other differently paged in Roman. I am unable to decipher all the peculiarities of this, but am obliged to refer partly to one, partly to the other, and occasionally to separates, as my copies run, or as I find indications in the references of others. I possess all the papers of the Annales series, and all but two small ones of the Bulletin series; but the accumulation was the w^ork of ten years. The work of Bigot should not be underestimated. He had a fine collection, and his types are now the property of Mr. G. H. Verrall. It is only a question of time until they will be elucidated; in fact, this has already been done for the Calyptratae (excl. of Anthomyidae) by Brauer, and for the Pupipara by Speiser. As the descriptions stand, it is often impossible to determine the species from them alone. It is not unlikely that some of them have been assigned to synonymy too hastily.

The number on Notacantha contains Cynipimorpha bilimeki n. g. et sp. and Myxosargus fasciatits n. sp., from Mexico. The last number, on the dipterous larvae, is a great work. The numbers on classification represent extensive research, and the system of Brauer seems to be widely accepted in Europe at present ; but I agree with Osten Sacken that classification is not the field in which Brauer has done his best work.

Many of the genera, after being ignored for half a century, have of late been adopted and newly defined, especially in Tachinidas. The work is intrinsically valuable, and for its time wonderful. The characters now used for separating the genera of Tachinidas were mostly introduced in this volume. It is very rare and expensive. Histoire Naturelle des Dipteres des Environs de Paris. 2 vols.

Before the publication of the Second Report, the first had been distributed under the title of First Report, etc.; 1855. This work contains 21 new American Diptera. Third, fourth and fifth Reports on the Noxious, Beneficial and other Insects of the State of New Y'ork, made to the State Agricultural Society, pur- suant to an annual appropriation for this purpose from the Legislature of the State.

With four plates and several wood-cuts. Contains a new edition of the papers on Cccid. tritici and destructor. All these reports appeared successively in the Transactions of the N. Y. State Agricultural Society, and were collected and issued afterwards as separate volumes: Volume i, containing Reports i and 2; Vol. n, Reports 3~5 : Vol. in. Reports 6-9. Each volume has a title-page, as given above, and a complete index of the contents. In the first and third volumes the pagination runs through the whole volume; in the second volume, a new pagination begins with every report, but at the same time, the species suc- cessively discussed are numbered and these numbers run through the whole volume. For this reason, in quoting the second volume, I had to give the number of the species referred to, while in quoting the other tw<> volumes, I give the page. Dr. Fitch's following Reports, which I have seen up to the I2th (1867), do not contain any new species of N. A. Diptera. Xotc. The above account of Fitch's writings is quoted bodily from Osten Sacken's Catalogue. It remains to add that the Reports were con- tinued to 1872. Limner, in his First N. Y. Report, 1882, pp. 291-325, gives a fuller account of the writings of Fitch. As I have copied all of Osten Sacken's references, I necessarily quote his editions, although the others were often earlier. Tnif>anca apirora (syn. Promachus fitchiiy is inadvertently omitted above. It is described in the 9th Report. Fletcher, James. Reports of the Entomologist and Botanist, Central Experiment Farm, Canada Department of Agriculture.

" Catalogue of the Insects of Massachusetts. In Prof. Hitchcock's Report on the Geology, Botany and Zoology of Massachusetts. Professor Hitchcock's Report had two editions; in the first (1833), Dr. Harris mentioned only the generic names of the insects, adding the number of species belonging to each genus. In the second edition (1835), the specific names are also given ; many of them are mere collection names, never having been published. "A Treatise on some of the Insects of New England, \\hich are injurious to Vegetation. Second edition. Boston, 1852. The first edition of this work was published in 1841, under the title of A Report on the Insects of Massachusetts, Injurious to Vegetation. The second edition contains many additions. "A Treatise on Some of the Insects Injurious to Vegetation. Third edition. Boston, 1862. With 8 plates and 278 wood-cuts. Was published at the expense of the Commonwealth of Massachusetts and is provided with notes by different authors; these on the Diptera are by C. R. Osten Sacken.

I give the dates of actual publication according to Hagen, although I observe that they do not agree exactly with Osten Sacken, nor with those penciled on my own set. The nominal date of publication was one year earlier, except with the first, second and eighth numbers. The work was also published separately, with different pagination, and this was used by Osten Sacken in his Cata- logue ; it is therefore continued by me. The parts without exception are indexed, so that any difficulty about the pages will readily be overcome.

Baron Osten Sacken's autobiographical volume contains so much infor- mation about the earlier work on North American Diptera, and the devel- opment of dipterological science in general, that every student of the order will find it extremely interesting and valuable. His rare and noble devo- tion to science throughout a long career should be an inspiring example. Packard, Alpheus S. On Insects Inhabiting Salt Water.

CATALOGUE OF NORTH AMERICAN DIPTERA. 6/ .Many new species, mostly described in a very brief and unsatisfactory manner. On Some Insects of Nova Scotia and Canada. Canadian Entomologist, in. 141 ; Oct., 1871. A short list of Diptera occurring in Nova Scotia: no new species. In the appendix to "The Naturalist in Vancouver Island and British Colum- bia," by J. K. Lord (London, 1866, 2 vols.). Walker described four new species of Diptera from those regions Cnlc.r pingitis, Laphria coluinbica, Cittcrcbra approximata and Enrygastcr septentrionalis. Note. Walker's descriptions are notoriously bad. Osten Sacken, Cata- logue, 1878, preface, p. xvi. has enlarged a little upon this subject. It was the policy of Osten Sacken and Loe\v not to adopt Walker's names unless, as is very rarely the case, the description contains some positive mark of identification. In their view, it was preferable to describe as a new species in doubtful cases. Some recent American workers have followed a differ- ent principle, and recognized Walker's species on mere preponderance of evidence; this I take it is especially true of Mr. Coquillett. It is desirable that each student of the order examine the descriptions for himself, and form his own conclusions as to the recognizability of any particular one. Furthermore, it is very desirable, in case that one of these specific names be resurrected, that the species be redescribed at the same time ; otherwise in most cases other entomologists will be completely in the dark as to the species referred to, and confusion will be increased. This pending a fuller knowledge of the type, which must some time be arrived at. Walsh, Benjamin D. Insects Injurious to Vegetation in Illinois. Rock Island, 1861 (pamphlet).

Aussereuropaische Zweifliigelige Insekten. 2 vols., with 12 plates; Hamm, 1828 and 1830. This great work contains very many North American Diptera. One of its objects was to elucidate the species of Fabricius, and nearly all the Diptera of that entomologist are redescribcd ; the original descriptions are also quoted in full. Another valuable feature is the redescription of a large number of Say's species, from material set on by Say himself, presumably typical in most cases. Wiedemann changed some of the specific names of CATALOGUE OF NORTH AMERICAN DIl'TKKA. 7 I these; where there seemed to be no valid reason for the alteration) I have followed Say in nomenclature.

CULICIM:. The discovery that mosquitoes convey malaria, yellow fever, filariasis, and possibly still other diseases, from one human being to another, deserves to rank with the greatest achievements of science. The immediate result, very naturally, has been an immense increase of interest in this family of Diptera, so that new I2O CATALOGUE OF NORTH AMERICAN DIPTERA. work is at present being published very rapidly. Theobald's Monograph, noticed below, gives a bibliography up to Feb., 1903, including early articles on the rela- tion of mosquitoes to malaria. I enumerate a few important publications. On Malaria, etc. Riley, Amer. Nat., xvn, 549, May, 1883, mentions the theory of Dr. A. Kink, Co- lumbia University, that mosquitoes cause malaria. Nuttall, Dr. Geo.

Delaware Water Gap, N. J. CECIDOMYID^. There are peculiar difficulties in the task of properly representing this family in the present Catalogue. On account of the fact that many species make galls on plants, we encounter here a mixture of botanical and zoological science, which has tended to separate the study of the Cecidomyidse from that of the other Dip- tera. Only those who have made a special study of the family are at all informed about it. L T nfortunately, not one of the present generation of American ento- mologists has given this special attention. To make matters ten-fold worse, the European specialists in Cecidomyidte 152 CATALOGUE OF NORTH AMERICAN DIPTERA. have come to a practical unanimity in accepting certain principles of nomen- clature which radically change the generic names used by Osten Sacken, who followed Loew. The change hinges on the application of the name Cccidomyia (disregarding for the time being the-new genera which have naturally come into existence), and will be found fully discussed in the following papers: KARSCH, Revision der Gallmiicken, Minister, 1878, 10-20. OSTEN SACKEN, Catalogue, 215, note i, 1878. RUBSAAMEN, Berl. Ent. Zeitsch., xxxvn, 324-327, 1892. KIEFFER, Annales Soc. Ent. France, 1900, 436. OSTEN SACKEN, Ent. Mo. Mag., 1901, 40-43. The practical effect of the changes adopted by Karsch, Riibsaamen and Kieffer is to apply the name Cccidomyia to the Diplosis of Osten Sacken's Catalogue, and to divide up his Cccidomyia between Rhabdophaga and Dasynenra. As nearly all the species in the family were referred to Cecidomyia and Diplosis in Osten Sacken's Catalogue, the adoption of the changed nomenclature will leave few members of the family in the same genera to which Osten Sacken referred them. Realizing the immense practical disadvantage of such an overturning of names, I should have been well content to let the problems of nomenclature lie in abey- ance; but they have been already threshed out in Europe, and the conclusions reached and put in use there cannot be ignored. After much consideration, I can find no better course to follow than to adopt the generic distribution of Kertesz, in his Catalogus Dipterorum, vol. n. Not having much knowledge of the family myself, and not being able to consult an American authority on it, I have carried out this plan. I take occasion to re- mark, however, that Osten Sacken thoroughly disapproves of the changes, and has given, in the last reference above, his reasons for his views. Some of the species still included under Cecidomyia doubtless belong to other established genera, but are not yet sufficiently described to allow of a positive reference ; in fact, many of the species need further study, and at best the present scheme must be considerably modified by more thorough investigation. No family of the Diptera offers greater inducements to a worker who will patiently carry on the biological and systematic study of it conjointly. The status of those names which have been applied to larva? and galls only, u, to pupae, larvae and galls, or even to galls alone, need not be settled at the present time. I have placed all such names in a division by themselves. My opinion is that when the adult is at last described, the same old specific name should be used, unless impracticable, but that thenceforth the description of the adult should be regarded as the real description of the species. Meanwhile, it is very con- venient, and thoroughly in accord with the objects of nomenclature, that the pro- visional name should stand. A few species described since Kertesz have been added, in harmony with his general distribution. Cross-references have not been thought necessary, considering the small size of the family. The European literature is voluminous ; Kieffer gives over 800 references. His Monographic des Cecidomyides d'Europe et d'Algerie, in Annales Soc. Ent. France, 1900, 181-472, 30 plates, is indispensable to any student of the family. I add here only a few references. COMSTOCK, Dept. Agric.

The only North American representative is the well-known "Hes- sian Fly," so-called from the supposition that it was introduced from Eu- rope along with the Hessian soldiers in the Revolution. It has uniformly been referred to the genus Cccidomyia in the past by American writers. The larva injures young wheat plants; it is found between the stalk and the sheathing portion of one of the lower leaves. The literature is very voluminous. Kertesz, in his Catalogue, n, 76, gives three pages of references ; Osborn, in Bull. 16, mentioned below, gives a far more lengthy list. I give a few of the early references, paying more attention to the newer publications, since the time of Osborn's paper. From the first, the articles are biological and economic in their scope. The European references are omitted here. destructor SAY, Jour. Acad. Sci. Phil., i, 45, pi. in, f. 1-3 ; Compl. Works, i, 4. Eastern U. S. FITCH, Amer. Quart. Jour.

I exam- ined the types at the request of Mr. Kahl, and as he expected, found one female of a Pachygastcr, and both the male and female of a species be- longing to a different genus, the eyes of the male being separated. These are all referred to in one way or another under the description of the female, which consequently becomes useless to science. LOPHOTELES. LOEW, Berl. Ent. Zeitsch., 1858, no. WILLISTON, Ent.

Note to the Family Acanthomeridas. There exists no reason known to me for maintaining the name Acanthomera against the apparently prior name Pantophthalmus, the adoption of which would involve a change of the family name to correspond. But I have not access to Thunberg's work, and it seems a very good rule to give the benefit of the doubt to current names. LEPTID.^. (Inclusive of Xylophagidae and Ccenomyidae.) BIGOT, Bull. Soc.

Zool.-Bot. Ges., i, i-ioo, 5 plates, 1901, is an admirable monograph of the European members of the family. BRUES, Monograph of the N. A. Phoridae, in Trans. Amer. Ent. Soc., xxix, 331-404, 5 plates, describes the genera of the world and all the N. A. species, with a new generic arrangement. It is dated 1903, but really appeared in January, 1904. This would exclude it from the present catalogue, which closes with Jan. i, 1904, but I deem it necessary to make an exception here, in order to avoid having this part of the work out of date on publication. There are full tables of genera and species, etc. ; it is a very valuable work. OSTEN SACKEN, Ent. Mo. Mag., sec. sen, xm, 204, 1902, discusses the position of this family. PHORA.

According to Mik, loc. cit., Rondani made an error of identi- fication, and the species he named as the type is not auctus, but has an acuminate third antennal joint. This antennal character is mentioned in the definition, hence Prothecus could not be used for the present group, in which the lack of a point on the third antennal joint is one of the principal characteristics. opaca WILLISTON, Trans.

SYRPHIDyE. WILLISTON, Synop. N. A. Syrphidae. Bulletin of The United States National Museum, No. 31. Washington, 1886, xxx and 335 pages, with 12 plates. The largest and most complete family monograph yet published on North American Diptera. VERRALL, British Flies. Syrphidse, etc. Gurney and Jackson, London, 1901. 690 pages, portrait and many excellent text figures. Includes also in an appendix of 121 pages a full catalogue and bibliography of the British rep- resentatives of the three families described, which are the Platypezidse, Pipun- culidse and Syrphidas. This massive volume is an encyclopedia on the three families indispensable to the advanced worker. Many of the British species and most of the genera occur also in America.

Note.- I dissent from the conclusions of Osten Sacken and Verrall in adopting Rondani's name here. In the first reference above, Rondani says, " Spec : typ : Musca pyrastri LIN.," and mentions no other species. Hence the proper procedure, in case the genus is illy conceived, is to revise its definition, rather than to make its type the type of another genus. I here use Lasiophthicus as if this had been done, exactly in the sense of Cata- bomba. pyrastri LINNE, Syst. Nat., loth ed., 594 (Musca) ', Fauna Suec., 2d ed., 448 (id.). Europe. FABRICIUS, Spec.
