Doalle, allel VAbbll B( p;in. ~r)le series in the Nationa.l Musenm eollection is especially v~~ lu al)le, co ntaining as it does a, Jr~I'ge llumber of bred Rpeeimens, whic!l, mol'c tban anytlliug' else, enables us to. correctly.iudge of the extel1t to which the varioul'l specimens of the same species will vat'y among tllclllselves. 'rhil:! col lhctioll ajso contains a duplicate set of a series of specimens sent to Brauer and Hergenstamlll, of Vieu ll a, A nstria, ill exchallg'e for n, named series of European form s, a nd the latter lll1ve been very val ' nable for comparison wit,h our own generl'l, and species. These autllorfl returned llames, principally gelleric, of the series seut to t llem, au(~ in the following' pager I have indicated' these identifications as "in litt." Mr. O. n. T. Townsend kindly sent to the Musoum cot.ypel'l of many of Ilis!leW pecies, and Mr. Ohm'les ]{ol>ertson generously donated specimens from tile same series as those from which Mr. Townsend, described several of hi s new forms. The region covered by this paper includes all of this country Ilortll of Mexico, bllt does Dot talce in any of the West J ndies. W hen the faunas of these two region s llave beeu carefull y compared with out' OWll, many additional species will no doubt be foulld to iuuu,bit two or even all of tllese regions. HABITS OF THE FAMILY. Among the fifty odd families iuto which tile Diptern, of this country have been divided, the Tachinidre is by far tile most I>eneficial, jaclged fr'om the standpoillt of all agriculturist. 'I'l l only otber family tin) at all competes \vith it for this honor is the Syrpbidro; but in thil:l family '7

7 8 only it comparatively small number of genera are directjybeneticial by preyiug upon plaut lice, and eveu ilt this respect their services could in most iustances 1.>e dirpensed with, since, as a general rille, the plaut lice are held in check by the larvre of ladybinls assistell by several kinds of internal parasites belonging' to the bymenopterons families BracolJid ru, Oynipida~, and Chalcididre. So fa,r as n,t present known the Tachlnid:n prey UJ)Oll living insects only, and by far the gl'ea,ter litunber of these are the leaf eating' cater pillars of butterfiier aud motbs, a group tllat contains a large number of our most iujnrious insects; and the nl11ube1's of theseclestroyed in a single season by these parasites is almost beyond computation. Unlike the pftrasitic Hymenoptera, each species of wlilch as :,}, rille colltines its H,ttacks to a sillgle group which in some cases ir restricted to one genui'l, it liot illfrequently happells that the same species of Tachiua fly a,ttacks several difl'ereut families of insects, while quite a 11l11D bel' are _known to attack two and ev!3u three different orders of iljseets--i.jepid.optel'a, Hymenoptera, aud Coleoptera. 'l'his lias been observed not only in onl' own couut,j'y but also in Europe., At present, only five different orders of insects-the three a1.>ove mentioned and the Orthoptera and HemipterfL-are ktlown to be attacked by the Tachinid!D in this country, but in Europe several cases are }'eported of their also attacking Diptera of tlle famjly Tipulidffl. Tue Lepidoptera, Hymenoptera, and Diptel'l1 are preyed upon in their pre, paratory stag~s only, whereas it is usually only the adults of t.lje Orthoptera, Hemiptera, and Ooleoptera tbat are attacked. The tachinid eggs are attached by fi, viscid substauce to the surface of the host, and tbe full grown larvm nsually ellter the earth to 11ass through their transiol'lllat ions. TIw lal'vm are of the usual maggot for III, large and truncated at otle end alld tapering to a point ill the oppol:'ite direction. Pupa,tioll talres place in tbe harc.lened skin of tile larva, which assumes a nearly cylindrical form with rounded ends, and is known as a puparium. In issuing, the adult fly breaks away the entire end of the puparium. It was formerly supposed that any caterpillar upon which olle of the e flies had fastened an egg was doomed to certain destruction, hut actual observation bas shown that this is not always the case, since in many im:tances the ca.terpilla,1', by molting or casting off its skin, rids itself of the egg before the latter has hatclled out and the yonng larva made its way iuto the body of the catp,rpi11ar. III 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 victinl alld deposit the egg within. In regard to the possession aud exercising of that faclllty commonly termed instinct, the Tachina flies appear to ue far behind the parasitic Hymenoptera. The latter seem to be able to ascertain, by a touch of their antennru wbether or not an insect IHIS already been parasitized, and ollly rarely insert au egg ill the body of an insect that already

8 9 contains an egg or 1arva of a pf1rasite, nor Itn,s one of them been known to consign a greater numbei of egg' to a ll i ll sect thau t1le number of larvre which tllat ill sect call maintain. On the contrary, a Tachiw1 fly lias repeatedly been known to attach to a calm'pillar t111'ee or fotu' times as many eggs as t he number of larvie the caterpillar can maintain. Owing to tllis fa,ct, a great mally taclliuid larvm luust n 'cessarily perish for want of food, wbilo several wbich have barely ll ad a sufficient quantity to keep t hem alive will be co llsiderably dwarfed in size, as compared to t heir more fort,unn,te brothers, and thus it will sometimes ]Ia,ppell that!'lome of til e adu]t flies will be ollly one-hall', and in rare instances even only one-third, as long as others which were tbe progeny of' the same parent. Oertain Rystematic wl'it,ers, who have had no expel'ienr.e in rearing these fiies, by great stress on a difference in size a,s indieative of a distiuct species; bu t our breedillg records have (tbulldantly. delnoll stra,ted the fact that one specimen may be fully tllree times as long as an other and yet both belong to one and the same species. ~'.A ClI lnid FLIES AND l'iieir 110S1'S.
