lVashiugton, 1). C.. June 2, 19i.
SIR : I have the honor to submit for publication the seventh of the technical series of bulletins of this I)ivision. It has been prepared by Mr. D. W. Coquillett, of the office force, and consists of a revision of the species of the parasitic flies belonging to the family Tachinida, which occur in the United States and Canada. The desirability of such a revision of these economically important flies has been apparent to all workers in economic as well as systematic entomology fir many years. They are amojig the most important enemies of many of our most injurious insects, and their characters are so obscure that workers have had the greatest difficulty in separating one species from another, and the result is that the literature of economic entomology in particular contains manity wrong determinations and absolute misstatements based upon such erroneous names. 1)uring the last eighteen years many species of Tachlinide have been reared at this office from injurious insects which were being studied. It has been heretofore impossible to record the results of these rearings on account of the confusion which existed in this family, and in its original conception this study of the group was undertaken in order to enable us to record the results of this biologic work. The records are now iveln in the shape of two tables-onme of parasites and hosts and the other of hosts and parasites-and a glance at these tables will be instantly convincing as to the important and beneficial rt^e which these insects play. With the clear and systematic diagnoses of the genera and species which Mr. Coquillett has prepared, any economic entomologist should be able to determine just wlat species of Tachina flies are assisting him in his work against injurious insects.
Respectfully, L. 0. HOWARD,

The present paper is the result of several years' study. and is based upon the large series of specimens contained in the National Museuin collection, mainly received from this office, supplIIelented by those inl my own and those received for study aid i(lentifi(ation from various correspondents, among whom may be mentioned: Mr. C. W. Johllsonl, Dr. Garry deN. Ilough, Mrs. A. T. Slossoin, D)r. W. A. Nason, Mr. Charles Robertsoin. Mr. Theodore Pergande, Mr. F. H. Chittenden, Prof. I. E. Wee(d, Mr. R. WV. D)oane, and L'Abb Bgin. The series in the National Museum collection is especially valuable, containing as it does a large numi)er of bred specimens, which. more than anything else, enables us to correctly judge of the extent to which the various specimens of the same species will vary among themselves. This collection also contains a duplicate set of a series of specimens sent to Brauer and Bergenstamm, of Vienna, Austria, ill exclange for a named series of Europ)ean forms, and the latter have been very valuable for comparison with our own genera and species. These authors returned names, principally generic, of the series sent to them, and in the following pages I have indicated these identifications as "in litt." MAr. C. II. T. Townsend kindly seit to the Museum cotypes of many of his new species, and Mr. Charles Robertson generously donated specimens from the same series as those from which Mr. Townsend described several of his new forms. The region covered by this paper includes all of this country north of Mexico, but does iot take in any of the West Indies. When the faunas of these two regions have been carefully compared with our own, many additional species will no doubt be foumd to inhabit two or even all of these regions.


Among the fifty odd families into which the D)iptera of this country have been divided, the Tachinida is by far the most beneficial, Iudged from the standpoint of an agriculturist. The oily other family that at all competes with it for this honor is the Syrphida,; but in this family

only a comparatively small number of genera are directly beneficial by preying upon plant-lice, and even in this respect their services could in most instances he dispensed with, since, as a general rule, the plantlice are held in check by the larvae of ladybirds assisted by several kinds of internal parasites belonging to the hymenopterous families Braconidae, (Cynipida,, and Chalcididale.
So far as at present known the Tachinid~e prey upon living insects only, and by far the greater number of these are the leaf-eating caterpillars of butterflies and moths, a group that contains a large number of our most injurious insects; and the numbers of these destroyed in a single season l)y these pa),rasites is almost beyond computation. Unlike the parasitic I lymenoptera, each species of which as a rule confines its attacks to a single group which in some cases is restricted to one genus, it not infrequently happens that the same species of Tachina fly attacks several different families of insects, while quite a number are known to attack two and even three different orders of in sects--Lepidoptera, I ymenioptera, and (' oleoptera. This has been observed not only in our own country but also in Europe.
At present, only live diflt rent orders of insects-the three above mentioned and the ()rthoptera and I lemipltera-are known to be attacked by the Tachinidae in this country, but in Europe several cases are reported of their also attacking Diptera of the family Tipulidae. The Lepidoptera, 1lymenoptera, and Diptera are preyed upon in their preparatory stages only, whereas it is usually only the adults of the Orthoptera, Ilemiptera. aind ('oleopl)tera that are attacked.
The tachinid eggs are attached by a viscid substance to the surface of the host, and the full-grown larvae usually (el iter the earth to pass through their transfirmatiois. Thel larv, are of the usual maggot form, large and truncated at one end and tampering to a point in the opposite direction. Pupation takes place in the hardened skin of the larva, which assumes a nearly eylindrical form with rounded ends, and is known as a puparium. In issuing, the adult fly breaks away the entire end of the pupariumn. It was formerly supposed that any caterpillar upon which one of these flies had fastened an egg was doomed to certain destruction, but actual observation has shown that this is not always the case. since in many instances the caterpillar, by molting or casting off its skin, rids itself of the egg before the latter has hatched out and the young larva made its way into the body of the caterpillar. In this respect the parasitism of these insects is not so certain as is the case with those hymenopterous parasites which puncture the body of their victim and deposit the egg within.
In regard to the possession and exercising of that faculty commonly termed instinct, the Tachina flies appear to be far behind the parasitic Hymenoptera. The latter seem to be able to ascertain by a touch of their antennme whether or not an insect has already been parasitized, and only rarely insert an egg in the body of an insect that already


contains an egg or larva of a parasite nor has one of them been known to consign a greater number of eggs to an insect than the number of larve which that insect can maintain. On the contrary, a Tachina fly has repeatedly been known to attach to a caterpillar three or four times as many eggs as the number of larvae the caterpillar can maintain. Owing to this act. a great many tachinid larve must necessarily perish for want of food, while several which have barely had a sufficient quantity to keel) them alive will be considerably dwarfed in size, as compared to their more fortunate brothers, and thus it will sometimes happl)en that some of the adult flies will be only one-half; and iii rare instances even only one-third, as long as others which were the progeny of the same parent. Certain systematic writers, who have had no experience in rearing these flies, lay great stress on a difference in size as indicative of a distinct species; but our b)recdinlg records have abundantly delnolistrated the fact that one specimen may be fully three times as lorig as an other a(nd yet both belong to one and the same species.
The following is a list of the Tachiiia flies that have been bred by this Division, together with the hosts from which they were bred. By ftr the greater lumber of these were reared in the departmentt insectary, in charge of Mr. Theo. Pergaii(lde. A few additional species, speciimens of which have been studied by the writer, are included in this list. Of the published re(.ords, only those are included where the flies have been bred from other hosts thanii those froimn which this l)ivisiou and its corresp)ondeiits have reared them; such species are indicated by asterisks (*) ini addition to the names of the persons who reared them and to the published references. A few of the breedifig records, which are evidently erroneous, are preceded by a mark of interrogation ( ).
The list is in two parts, arranged alphabetically:

Probably iio sillo-le family of Diptera has received greater consideration in. Eurcllw Ulan the Tacbini(la,7 -and yet, strangre.A. ; this may seem, iio o 'lier family at the preseiit time is in L)-reater disorder. Several authors accord theni only subfi-imily rank, but it appears desirable to consikler tbein as a distinct family, .11thou(ji their relationsbil) to the Dexid,e and Sarcopliagid,( is ,,t very intiiiiate one. They iii-iy be recognized by the bare, or at least never pluniose, anteiiiial arista. They are coniinonly divided into live subfainilies, and these have by one or two writers even been 1tecorded family rank. The characters employed in separating them are as follows:

So far as our own fauina is conceeiied, the species, are too nearly related to one another, -both structurally and also in, recrardl to their habits, to perinit of being separated into stnai~er groups with any degreee of satisfaction.
Only a Feaw terms employed in the p~resenlt wokwill require all explanation, since iii most cases the terms used ini des44utatig the various parts of the speciniens are the same, as, those emptloyedl iii the therL departments of t' omllolgy.

(-)ne Eu-tropean author, Mr. Girschmer, proposes to separate the Tachnda' into two groups according to whether- this bristle is p~resenlt or ab~sent, but in somne of our species it is present in some specimens but absent iii others thiat belong to the samiie species; this character, therefore, is not of specific, much less of subfamily, import-ance. The stern~opleiral inacrocliaeta- a,.re situated on. the upper part o)f the transverse, imore or less triangular, piece located on the sides of tile thorax between the front and i(I dle coxa-1; when only one is present, this is the lposterior; when. two, these are, the anterior anol theplosterior: when three, two are in front and one b),hind ; andi~ when fo)ur, these are ini a dlowniwardly curving row.
Tihe macroehmtw ou the dorsumti of' the abdomen are called discat


when situated near the middle of the length of the segment, and marginal when located near its posterior margin.
The veins and cells of the wings are called by the same terms as inll the other families of D)iptera, except that the first posterior cell is commonly called the apical, alndl the portion of the fourth vein beyond the bend is sometimes termed the ((pical crossrcin.


The only attempl)t at publishing a synoptic tabl)le, comprising all of the genera repl)orted as occurring in North America, is that by Mr. C. I. T. Townse md, in the Proceedings of the Entomological Society of Washington and in the Transactimons of the American Entomological Society.2 That in the former publication is a reprint of the table given by Dr. Schiner,3 and that in the latter a reprint of the one by F. M. van der Wulp, both modified so as to comrise only the North American genera. As the author did not have access to specimens of many of these genera, and as the characters he uses are in many cases nit of specific, much less of generic, value, the result is not altogether satisfactory, and I have therefore constructed an entirely new table,
which, however, includes only those genera from America north of
Nexico of which I have examined representatives. A list of the remaining genera reported Ifrom this region is given at the end of the table.
In some cases doubt will arise as to which section a given genus should be referred, but in such cases, at least so far as they occur to the writer, the genus is placed in both sections:

A linear arrangement of the genera of the Tachinidw, so as to indicate their iiatural relationship is quite impossible, owing to the fact that in several cases each of three genera is more closely related to a fourth than to any other genus, and in a linear arrangement it is, of course, impossible to place each next to the one to which it is nearest related. The following arrangement shows the relationship of the genera given in the preceding table perhaps as nearly as can be done in a linear manner. By this arrangement, those without strong macrociTtT on the abdomen are placed at the opposite end of the series to those having these macrochqetfe the most strongly developed:

The arrangement of the genera is that given above. In the case of synonyms, the oldest name has been adopted, since this method is the only one whereby a uniform system of nomenclature can be obtained. On the other hand, if we follow the law of favoritism we can never hope to have a uniform series of names, since the German student will adopt the name proposed by a German, thie Frenchman one proposed by his own countryman, and so on. All of the synonymy given inll these pages has been verified by the writer. By a few authors the names of certain genera have been rejected, owing to the fact that the author described under each of them species that properly belong to two or more distinct genera, but this does not at all invalidate the genus, since the name may be retained for one or more of the species and new generic terms applied to the others. Again, certain genera have been rejected on the score that they have been insufficiently characterized, but if one of the species that the author placed in a given genus can be identified with reasonable certainty, the generic characters can readily be ascertained from an examination of the specimens themselves.
General Iounded on characters peculiar to one sex only have not been adopted. The writer is of the opinion that in case the females of any two given species are structurally identical, these two species should not be separated into differejit gene a, no matter to what extent the males of these two species may diffteri from each other. Any classification that will not enable us to refer a single specimen of either sex to its correct genus must necessarily come short of the very object for which it x\ as designed.
The following pages contain references to all the species of Tachinide hitherto reported as occurring in this country north of Mexico and belonging to genera of which the writer has examined representatives. Only the species studied by the writer are tabulated; the others are listed at the end of the tables. Genera of which the writer has seen no representatives together with the species from this region referred to them, have already been listed on previous pages. The localities given are those in which the specimens studied were captured; the published records have not been added, since it was intended to make the present work as nearly original as possible. The color of the halteres has been purposely omitted as of no specific importance. Types of all the new species have been deposited in the United States National Museum.

The synonymy of the first two is according to Schiner. Brauer and Bergenstamm state2 that Desvoidy placed in Medina species belonging to Admontia and I)egeeria, but they do not specify which of these species belong to Admontia. Since all of the recognized species placed in Medina by Desvoidy at the time of describing this genus belong to D)egeeria, there would appear to be no doubt concerning the identity of these two genera. The identity of Amedoria with Degeeria has already been acknowledged by Brauer and Bergenstamm." Our single species is black, with a brown tinge. the calypteres yellow, the wings strongly tinged with brown at the base and in front of the fifth vein; three postsutural and three sternopleural macrocleita,, discal mnacrochietze on the last three segments of the abdomen; length. 9 mn.
