By SA3ILEL IIUBBAED SCUDDEK. INTRODUCTION. The present essay describes in detail iind discusses the classifi- cation of a group of grasshoppers which forms the prevailing type of orthopteran life throughout North America — the common short-horned. grassho])i)ers one sees every summer day. Its best known representa- tive to the world at large is the destructive migratory locust of the West, the so called '* Kocky ^Mountain Locust."' The outbreak of this insect has been at times extremely disastrous; so much so that a Gov- ernment commission was for several years iu existence, which pub- lished nearly twenty years ago two voluminous reports in which it and one or two of its immediate allies were studie«l with a minuteness and thoroughness, and illustrated with a fullness very rarely given to any surh insignificant looking creature. This destructive insect has nniijerous closely related allies in all parts of the United States, many of which often abound to such an extent as to do serious damage to crops, and a few of them have been known to migrate in similar fashion (though over a far more restricted area), so that they have sometimes been mistaken by the uninstructed for that destructive pest. The grt)up is almost confined to North America, and a great many species hiive been described by various writers in a more or less rominent, never twice as long as the intraocular portion of the genae, the interspace between them very rarely broad, generally narrow ; the fastigium is more or less declivent, never greatly i)roduced in the axis of the body, apically entire and with no transverse ruga, passing insensibly and with obtuse arcu- ation into the frontal costa; the latter is hardly rounded as seen from the side, percurrent or subpercurrent, generally sulcate, the sulcation ordinarily confined to the lower portion: without foveolae, the tempora small, obliquely declivent, confused with the front; the superior ocelli more distant than the antennal scrobes; the lateral carinae of the face nearly equidistant from the lateral margins of the frontal costa, but slightly divergent inferiorly. The dorsum ot the pronotum is nearly plane and without a crest, generally with no distinct lateral carinae, but at most with rounded shoulders or feeble rugae to represent them, but often passing insensibly into the lateral lobes; the principal sulcus is continuous; the prozona is generally smooth or obsoletely i)unctate, never tuberculate, its sulci generally feebly impressed, often mesialiy interrui)ted or subinterrui)ted, the i)osterior sulcus often distinctly divergent laterally from the principal suh'us; the metazona is generally shorter than the prozona and lies iu the same or nearly the same plane with it, almost always densely punctate; the lateral lobes are truncate or subtruncate posteriorly, with no humeral sinus or only a feeble one. the posterior lower angle distinctly obtuse. The prosternum is armed with a spine which is usually rather prominent and conical, sometimes truncate, never sinuate, generally vertical on the posterior face, nearly or quite as high as the anterior coxae, the posterior portion of the pro sternum not or but slightly tumescent; the roesosternal lobes are quad- rate or transverse, separated more or less widely, the apical inner angle rectangulate or obtusangulate, generally rounded Coften obtusely), tie inner margins generally rounded, often posteriorly divergent; the meta sternal lobes are contiguous or not very distant excepting sometimes in the female and then rarely as distant or even nearly as distant as IN.. 1134. BEVISION OF THE MKLASOVLl^SCVDDElt, tlir iiieso8teriial lo]>es. The tetriiiina are frequently abbreviate or even M anting; when fully «lev<'l()|MMl, they t;ii>er ^jently alinoHt tlirou;rli(mt and are rather remotely retieulate at least in their apieal half, the cells oC tin- jK)8tra(lial area wholly or partially biscriate in arrnn^enieiit on either side of an intorealary vein; the win^^s are almost always elear and uniform, never detinitidy i)ictured, the veins never sealariform, the ill eolae (|uadrate or lon«(er than bnnid. All the tarsi are furnished with ail aroliiiin, the front legs are less distantly separated than the hind p;iir, the fore tarsi are of moderate lentfth,the tirst joint short or rather sliort: tiie hind femora are distinctly iiierassute basally, ;i:enerally sur- piiss the abdomen, the upper face fjenerally smooth, the dorsal carina eiitin', unarmed, not profoundly excised befoie the jjeniculation; the bind tibiae have smooth lateral marfflns, the spines of the outer and inner <«Mie8 are equal or subequal in length, those of the outer series typically nine' or more in number, rarely exceeding fourteen, ])laced at subequal distances apart and lacking an apical spine next the calcaria; the hind tibiae have the lirst Joint not compressed, equal to or slightly longer than the third, the second much shorter, generally a half shorter, than the tirst as seen from above. The second dorsal segment of the abdomen is neither granulate nor dentate at the anterior angles, the extremity of the abdomen in the male generally more or less clavate and recurved, the supraanal i)late not tuberculate, with a basal median sulcus, a furcula usually present, the cerci very variable, rarely longer than the supraanal plate, straight or gently curved, never abruptly recurved basally, generally compressed at least in part, often laminate^ but with no indireeted median spine. The foundation for our present knowledge of the structural features of the Melanopli was laid by StiU ^ and enlarged in his Systema Acrideodeoruin (1S78) and his Observations Orthopterologiques, II£ (1878). In its present form the groui) was first detined and named by Brunner von Wattenwyl,^ who applied to it the terra Tezotettiges. I have here limited it strictly in the same manner, but it will appear that it contains a very much larger number ot generic types than were credited to it by Brunner and a vast multitude of species. I shall moreover show below, when treating the genus Podisma,* that the gen- eric term Pezotettix, from which Brunner derived the name of the group, has been misapplied of recent years, and should be referred to the group called Platyphymata in Brunner's Bevision. I have accord- ingly here named the present group Melanopli after its predominant genus }felanoplus, the species of which far outnumber all the others com- , bined. Giglio Tos in recent papers has described several new genera and I ' By exception, in one sex or on one side of the body, there may be only eight. f '^Recensio Orthopteromm, I (1873). ^ =5 Revision du Systeme des Orthopterea (1893). ^ ^See also Psyche, VII, pp. 195-196. 4 i*BtK:Et:ins(is or the sational misjcim. vouxx Hpcrics tVoiii South AriKM'ica; hut in the prt'Ncnt paper t'liil coiisideriition will h<' ix'VtMi only toth«* Noitli Amcriran species; jitahle will, however, be Hossesses four ;j:enera ( not included in the juesent paper) — Dichrophtn^ Srotusna^ Scopan, and A tnichelacris, with ab(»ut twenty known species mostly referred to PichmpluH, besides ruruilichrtr '.uH^ with four species in l*aragruay.

There are but few species which range across the continent, yet not a few have a very wide distribution. The examples of the former are wholly contiiied *o Melanoplus: M. Gthuiis, fa-sciatus, fcnnir-ntbrum, eatremHs^viinor.nud/emoratas, }f. ertrcmus only in the high north. As illustrations of the latter may be mentioned Hespcrotctti.v pratensis^ Fhoetaliotes nehrascensis, Paroxyn iioridann, OedaleonotuH enic/ma, and the following species of Mehtnoplus : fiabcUi/er, spreiun, Hciidderi^dmr- son',, cinereus, Packard a, luridus, difrrentialis, biviftatnx, and pnnctnla- tu8. Most of these range more widely from north to south than from east to west. About three fourths of all the species are known from west of the Mississippi River only. Dimorphism in lenfjth of tegmina. — We find in the Melanopli every variation possible in the length of the tegmina, but the species are in general tolerably well tixed in this respect. The same is the case with most of the gener; . the species of which are in each case generally apterous, provided with lateral pads, abbreviated tegmina, or fully 6 ' PROCEEDINGS OF THE NATIONAL MUSEUM. volxx. developenff/i//«off',s') and some of the smaller show considerable diversity in this respect; the greatest difference between different members of the same jnfenus obtains in the two largest genera: Melanoplus. where the speiies may range from those with merely lateral pads to those with tcgmina far surpassing the hind femora; and Podisma. where they range from apterous species to those with tegmina lialf as long as the abdomen, lint tiiis range is not confined to the larger g«*nera, for sev- eral monotypic geuera {Dernlrotettir, PhoctnUotcH. and Ocdaleonotun) dis- play a wide difference between different forms of the single si)ecies they ])ossess, in the length of the tegmina, a differeiu-e which is also paral leled or almost i)aralleled .iinong certain species of the genera Hespero- tetfi.v, roili-smaj Melanojjiusj and I'aroxya^ and particularly of the genus Mclainqilns.

Mr. Ulatchley informs me that at the time of his visit the snow line was at 15,000 feet, and adds that he took a single specimen of the specie^ at 13,500 feet, "a very few individuals may have been taken as low as 9,000 feet, but the species was common only between 10,000 feet and 12,000 feet; above 12,000 feet scarce." According to statements in the daily press,^ Orizaba, which is o volcanic origin, showed signs of a ^" lewal of activity early in Marcli. 1895, when hot ashes were ejected, the snow disai)])eared from the sum mit and the vegetation of the ui»per part of the mountain was buriHii Possibly this means the extinction of Paradichroplus mexicanus.

The general color is a greenish yellow more or less tinged with brown, brighter in the male than in the female, and marked with blackish fuscous; the darker markings consist, i)rincii)ally, of a dorsal stripe, which either extends over the pronotum as a broad equal band, often fainter in the middle, with a triangular extension on the head, and sometimes a narrowiiij,' iufuscation on the meso- and metanota (male), or forms an obovate patch along the middle of the anterior lobe of the prothorax, with the same triangidar extension (m the head, and reap]>ears sometimes on the meso and metathorax, and always on the abdominal joints, as a series of obliquely-descending, triangular, lateral patches, separated from one another by a yellowish median line (female) ; also of a broad lateral band, which extends from behind the eye backward, either to the hinder edj,'e of the prothorax, its upper margin straight, its lower arcuate (male), or across the prozona only, occasionally in an obscure manner across tlie metazoua also, both margins arcuate (female); beyond this the latera band extends over the remainder of the thorax and over the abdomen, often broken into spots on the latter, and always enlivened on the for- mer by anoblifjue yellowish line, which crosses it on the metathoracic episterna. The face partakes of the color of the under surface, as do tlie bases of the antennae; beyond, the antennae become slightly rufous just behind its narrowest point the vertex has a transverse blackish line.

Hesperotettix Scidder, Hull. U. S. Geol. Surv. Terr., II (1875), p. 262. Body almost parallel-sided, very little enlarged at the metathorax, more or less but not greatly compressed, more so in the male than in the female. Head not very prominent; vertex usually very narrow between the eyes, with a slight depression or sulcation between; fastigium broadening in front of it, declivent, with a median depression or longitudinal sulcation, sometimes distinct, sometimes obscure, the sides rounded; front straight, somewhat oblique, the frontal costa equal, only slightly contracted at the extreme summit, generally as broad as if not broader than the interval between the eyes, sulcate throughout; antennae sHghtly (female) or considerably (male) longer than the head and pronotum together; eyes slightly prominent, a little more so in the male than in the female, rather long oval, much longer than the infraocular portion of the genae. Pronotum long and slender, the dorsum fully half as long again as broad, the prozona the longer, sometimes half as long again as the metazona, with less distinction in surface and sculpture between them than common, alike broadly tecti- toiin, the median carina slight but alike or nearly alike in both, the descending lateral lobes separated by no angle or ruga; posterior mar- uiii very obtusely angulate, the angle rounded, the border delicately imirgined. Prosterual spine rather long, bluntly conical; meso- and 56 riKtCEEUlNGS OF THE SATIOSAL MlSEl M. vouxx. metastetliia together mucli longer tliaii broad; interspace between niesosternal lobes generally twice as long as ]»road in the ujale, almost equally narrow or snbqiiadrate in the female, the metasternal lobes subattingent in both sexes. Tegmina and wings always present, gen- erally fully develoi)ed or a little abbreviate, but sometimes lobate. Fore and middle femora of male tumid; hind femora long and slender, somewhat compressed, generally surpassing the abdomen, the superior carina slight, unarmed; hind tibiae feebly ampliate apically, with spines of similar length on the two sides; first joint of hind tarsi scarcely longer than the third, the second small, with a large inferior apical lobe; arolium rather large, nearly twice as long as broad. Sub- genital i)late of nude furnished with a prominent, subapical, mine or less conical tubercle, the lateral nuirgins of the plate suddenly ampliate at base; furcula always distinctly present as a pair of projecting lobes; last abdominal segment of female not abbreviate, the ovipositor nor- mally exserted. The type is H. festivus Scudder, a species mistaken for //. viridin Thomas at the time the genus was described. This genus is closely related to Hifpnchlora and (Unnpylncaniha^ but is separated from them by the basal ami)liation of the margins of the subgenital i)late of the male. One of the species indeed (the most aberrant one) was originally placed by Brunner in Hi/poelilora. The genus is still more closely allied to Aeoloplusj from which it is separable by the form of the pronotum and the slenderness of the body. It is found across the United States, but only a single species is known east of the Great Plains, and that one has only been found on or near the Atlantic border. It is generally characteristic of the West. Many of the species are very closely allied and have hitherto been confounded by all observers. A large amount of material now enables nje to distinguish them and to find characters which will rarely fail of tolerably certain separation. ANALYTICAL KEY TO THE SPECIES OF IIE8PEROTETTIX. A'.

Localities which are in doubt or in error are placed in brackets. This species closely resembles H. festivus^ but while generally of a little larger size is distinguished from it by the black-marked sulci of the pronotum, the generally but not invariably greater irregularity of the markings of the lateral lobes of the pronotum, the red annulation of the hind femora (though this will probably be found in some individ uals of H. festirus) and the ground color of the head and pronotum, as well as in slight diti'erences in the abdominal appendages of the male. The eyes are slightly more elongate iu H. festivus than in the present species, at least in the female. It is wholly uncertain to what species belongs the reference by Thomas' to an insect with tegmina only one-third the length of the abdomen, taken in northern New 3Iexico or Colorado.

Wellesley, Norfolk C-ounty, ^lassachusetts. July 1(>-August 1 (A. P. Morse); New Jersey (U.S.N.M. [No. 711]): Georgia, Morrison. This species has been previously recorded only from New Jersey (Thomas, Thler), where Uhler says it is "not uncommon in the cran- berry fields of Atlantic County;"' and from Wellesley, Massachusetts, by Morse, who tells me that his specimens were taken in a very restricted locality, "a steep gravelly hillside, formiiig the terminal por- tion of a part (^f the gravel-plain formation of Wellesley." where they were captiu 'by sweeping vigorously the short-tufted growth of bunch grass, ^±uaropo(jo}i ncoparius, which with other wild grasses and running blackberry vines sparsely clothed the gravelly soil." All his specimens were taken between mid July and mid August. Since writ ing me this, 3Ir. 31orse has found another locality near the previous, whereon July 10 he tork both sexes mature and nymphs; the surround- ings were similar. This species is very closely allied to //. pratensis, but differs from it in its shorter tegmina and wings, the more regularly conical cerci of the male, the slightly different form of the supraanal plate and the markings; it is also of a smaller size. 7.

The specimen above referred to from Orizaba, a female, differs slightly in its somewhat abbreviated tegmina, and the mottled mark ings of pallid yellow and green upon the lateral lobes of the i)rono tum; it possibly indicates another s})ecies. 8.

It is said by Bruner to occur also in southeastern Nebraska, southern Iowa, and Illinois. 1 have retained the name qucrcus rather than louf/ipennis for this species for several reasons: It was first called by this name both by lliley aud Bruner; it was first described in its earlier stages under this name by Packard (coi)ying Bruner's description, which was unaccom- panied by a name); and the name is a far more fitting one than longi- tHtniis, considering that the insect appears both in brachypterous and inacropterous forms, and that it is normally brachypterous, as the basal divergence of the tegmina shows. It may also be called a mistake (in wliich entomologists generally have erred, myself among them) to give any species of Orthoptera a name derived from the length or brevity of tiic tegmina. On the other hand, indubitably the species was first fully described from mature examples under the name longipennifi, a name given by Kiley on the assumption that it was distinct from his earlier iiaiu'd miercus. As both names were given by the same naturalist, no IHTsonal question enters, and I trust that in this settlement of the ques- tion at its first raising all will agree. 04 VUOCEEDIKGS OF THE XATIOXAL MUSEl'M. volxx. Oiii- knowledj^e of the naturcil history of this 8peci«*8 dei)eml8 almost entirely upon what Uruner wrote in his lirst aecount of it in 1S,S7, before it was named. He found it in destruetive numbers in Wasliinj;- ton County, Texas, feedinj; upon the post oak aiul "completely defoli atinjjf the trees of the forest even to the very topmost twigs." He gives the following account of its history and habits: The ej;>; pods are depositiMl in the <;i°oiin(l about the bases of trees or iiulilVrrentl.x scalttTi'd about the siirfatM' aiii<»ii«; the decaying heaves, etc., like those of all otiiiT groiind-hiying species. The young «'onunenfe hatching about the middle of March, and continue to appear until into Apiil. After molting tlic lirst time and becoming a little hardened they immediately climb up the trunks of the trees and bushes of all kinwth after leaving the egg. The larva and i)Upa run up the trunks and along the Iiml>sof trees with considerable sfieed, and in this res]»ect differ consiroader than tlie lobes them- selves; metasternal lobes le length; furcula usually developed, but only at most to a small (h'gree; ovipositor of female variable, typically exserted, but sometimes exceptionally extended and at others i)artially withdrawn in the then obtusely terminating abdomen. The limits between this genus and Melanoplus are diflticult to formu- late; while there is no ditliculty in sei)arating the bulk of the species ill either group, there are a number which tind their place almost e(iually well in either. I have here attemi)ted to state anew the char- acters tirst expressed by Stiil, though with such necessary moditica- tions and expansions as a far larger series of forms entails. I can bardly hope that the conclusions 1 have reached will be sustained at every point, but I am confident that they must hold in the main. In doubtful cases I have endeavored to determine the atlinities from the Concurrent study of both sexes and not from either alone, which would have brought about other and sometimes discordant results; and I have assigned the greatest weight to the intervals between the sternal lohes. As I have here employed a ditferent generic term from that in cur- rent use in literature, I submit the following cogent reasons for the necessity of the change: The generic name Fodisma was proposed in a Gallic form {Podisme) A sin^]e exception is known to me in the subapterous Japanese Pndisma dairisama. ^vll(•^e it is slightly longitudinal. i)f) PROCEEIUXGS OF rilE SATIOS'AL MISKI'M. vol.xx. l)y liUtrL'ille' in 1.Hl'."> torslu»rt-wiiij;r«l Acridisiiis witli a prostenial spine, without sjKM'incation of spccit's.

The iniblication of Fieber's species dates from 1853 (Lotos) ami not from 1854 (Synopsis), and antedates bv several months the description of Fischer, whose name has been hitherto accepted ; for I'iebers si)e- cies was published in the June number of Lotos, and the preface to Fischer's work is dated November. This species occurs, according to Brunuer von Wattenwyl, on hazel stalks and bramble bushes.

As Brunner points out, this is not the Podisma sehmidtii of Fieber ( !>*>;)); but he nevertheless retains Fieber's name for it, because it was tir.st described by himself under that name, under the supposition that 116 rROCEKDiyc. .S of the XA TIONA L MVSE VM. vol.

This species differs from the preceding two in the uniformity of the pronotum, which does not expand posteriorly, and has a uniformly shar]) median carina throughout; it is also lighter bodied and less heavily marked. 2. FLABELLIFER SERIES. Ill this series, one of the few which combines macropterous and bra- chypterous forms, the male prozona is feebly or distinctly longitudin- obsole e, exce[)t in a single instance where it is small. The cerci are broad, often excessively broad and tlabellate, enlarging from the base toward the middle, at least in the macropterous forms, rarely as much as twice as long as broad, broadly rounded apically. The subgenital ;»i{ite is short and broad, sometimes with a slight apical tubercle, the lateral margins straight, the apical margin not elevated, or only in a single instance.

The two species placed together here have comparatively little in common to warrant their combination as a series, and each should perhaps be made the basis of a distinct series if other forms are found allied to one and tho other: but falling together by the characters given in our table, I have thought it best for the present to connect them. They have these common characteristics: The mesosternum in front of the lobes is plane in the male. The more or less maculate tegmina extend only to the tip of the hind femora, and the hind tibiae have from ten to twelve spines in the outer series. The supraanal plate is simple, without elevated sides; the furcula is devel- oped as a pair of minute triangular denticles; the cerci are broad and short, only abcmt twice as long as broad, a little upcurved, and apically broadly rounded, while the subgenital plate is moderately broad, pro- longed, and scarcely elevated apically. The species are of small or medium size; one occurs in Texas and northern Mexico, the other from Montana to Alaska. i6. MELANOPLUS GLAUCIPES. (Plate XI, fig. ♦!.) CaloptenKS ylaucipis ScrDDERl, Proc.

Tbe publisbed accounts add very little to tbe above range of distri- bution, except tbat it is rejiorted from (^>uebec (Provancberj, nortbern Californiit (Packard), Nevada (Scudder), and soutb as far as middle Florida — probably by error (Packard). It is i)robable, tberefore, tbat it is found in every part of tbe continu- ous district of tbe United States, excepting in tbe soutbernmost Atlantic States and most of California, being tbus limited very mucb as M.ftinin- ruhrnm ; it extends also into central Mexico, and nortb of our boundary is fountl from Atlantic to Pacific as far at least as latitude o(P (except- ing Newfoundland), and on tbe Pacific sidereacbes nortb to tbe Yukon River and probably tbe Lower McKenzie. Next to .1/. spretus tbis is our most destructive locust, and east of tbe ^lississippi jirobably tbe only one ever doing mucb damage. Its injuries, bowever, are not for a moment to be compared witb tliose inriicted by M. sprettiSy for, tbougb possessing good powers of tliglit and on rare occasions known to migrate in swarms, its injuries can only be classed as local, and tbey are never so serious as tbose inflicted by M. S2)yettis : nevertbeless tbey are by no means sligbt, and immense destruction of grain is to be laid at Us door. Bruner, wbo lias studied tbis insect over ^ vide extent of countrv, snvs that "wliile it occurs over . . . an exi ';«(• 'd territory, it appears to be . . . partial to liill.v NO. 1124. BEFISIOX OF THE MELAXOPLI—SC UDDER. 183 or iiiountaiiious regrions . . .; it seems also to prefer a wooded or mixed country to the open juairies or plains." This is one of the most variable of the Melanopli, and it is some- times ditticult to distinjiuish from its immediate allies. The abo.e description is drawn up primarily from Eastern examples which came from the rejiion from which the species was origfinally described. Specimens from the dry plains of the West (especially noted in those from (Jtah)are decidedly paler and more cinereous in aspect than those from relatively fertile country, and they have often a Havous stripe borderiufi' the eye and continued ahnig" the position of the lateral carinae: a similar but not so striking;: a cinereous hue attaches to those tliat occur in sandy localities in the Eastern States, as along the sea margin. The exact contrary is shown in Canada just east of the Rocky Mountains, where the s[>ecimens are exceedingly dark in color, almost blackish fuscous, with heavy fasciation of the hind femora: ' but here again a difference of anotlier sort occurs as one i^asses eastward, speci- mens from Laggan and Bantf almost invariably having relatively long and slender male cerci, while at Calgary all that have been seen (with a very few from the former localities) have male cerci hanrv more than half as long again as broad. Specimens from Mexico, vever, agree very closely with those from Xew England. Sjjecimens with green hind tibiae have been seen by me from the White Mountains, New Hampshire, but not from the summits (except Krarsa-rge 3,l.*51 feetj, from the vicinity of Boston, at Provincetown, and on the island of Nantucket, Massachusetts, from Laggan, Alberta, the Yellowstone region, Montana, Wyoming, Nebraska, Missouri, C(»lo- rado, from the Salt Lake valley and American Fork Canyon (9,500 feet), Utah, Texas, and Chihuahua, Mexico. Specimens with dark blue hind tibiae have been seen from Iowa. Colorado, American Fork Canyon, rtah, and Texas. In nearly or quite all these cases specimens with red liind tibiae predominated in the same district. According to Rilev the first mature insects observed one vear about St. Louis, Missouri, appeared July 12, and deposited eggs by July 20. The eggs had a ([uadrilinear arranjiement in the pod, hatched in from three to four weeks, and the young took eighty days to reach maturity. He says he has proved that the insect is there double-brooded, though I find no data published by him in support of the statement, and the above facts drawn from his writings militate against it. Bruner, how- ever, agrees with it, saying that in the District of Columbia a second brood ai)])ears in the late autumn, composed of smaller and darker individuals. I have seen nothing of the kind in New England. The points in which the unfiedged locusts dift'er from the same stages in M. sprctus and M. femur ruhium are explained and figured in the tust rei)ort of the United States Entomological (Joramission. in which many other interesting points regarding this species will be found. Speiiniens from Sutlbury, Untario, are siuiilarly dark. 184 PliOCEEDISGS OF THE XATIOXAL MUSE I'M. vol xx. 27. MELANOPLUS SPRETUS. (Plate XII, ti«.8.) Caloplenm apntiis UhlerI, MS.

I refrain from giving in detail the localities from which 1 hav e seen specimens, both on account of their number .md because, from the irregular distribution of the insect in different years, such details would have little value without dates, which are not always accessible: farther on, however, I give all that are of special interest. The name of this species is to be credited to ^l\\ V. W. Thler, who )>laced it in his collection thirty or more years ago and communicated it to various persons, who used it. sometimes in an incorrect form. The original siJecimens were received from Mr. Kobert Kennicott, and were obtained by him from a migratory horde which settled in the then Red INver settlements, now Winnipeg and vicinity, Manitoba. On Mr. rider's generous transfer of his collection to me, these specimens, with their history, came into my possession, and I now have them with his (•riginal labels. One has been placed in the National Museum. It was thus known from the start as a migratory insect, and com- paring it with any species of the genus one would at once be struck with the greater length of the tegmina and wings. These were meas- ured bv liilev; in fortv-eight males the tegmina extended bevond the abdomen 5 to 10 mm., with an average of 7.0 mm. : in ninetj'-nine females they ranged from •'» to 10 mm. beyond the abdomen, the average (».7 mm. It is now well known as the "Kocky Mountain Locust " or destructive locust of the States in the western half of the ^Mississippi Valley. It has beeu njore written about than any other American Orthopteron, and was specially discussed by the Tuited States Entomological Conunission, organized to devise methods of checking its ravages after a study of its natural history. It forms thp almost exclusive subject of their tirst report, and occupies a considerable space m their second. AlthougU a considerable body ot the evidence adduced by them is contradictory and in part of doubtful application to this ])articular species, their con- clnsiojiis are in very large measure well founded. As ai)pears from a study of their work and other available material, the following conclu- sions mav be fairlv drawn : (1) Th(i home of the species is in favorable localities in the elevated region of the Ilocky Mountains or immediately boroering it from the 188 PEOCEEDl^GS 01 TUE SAJWSAL MUSEUM. vol.xx- South Saskiitcliewaii to AVyoiiiiiij;, iiiclusivt*, juid in tlie Kockj' Moun- tain region projuT in Colonulo and Ttah. (2) In certain years, especially in dry seasons, between mid-July and' mill September, migratory hordes of incr<'dible ninnbers and of both sexes pass from their natural breedin*; «?r(mnds to the east, southeast, and south, conveyed by the winds (toward which they head) over a greater or less and sometimes a vast extent of country frou) Lake Win- nijieg to or almost to the (inlf of Mexico, rarely ]>assii<;i' fartlier east than lon<»itu«le U3^, and devastating- the countries they reach to an alarming extent, sometimes in places abstdutely destnninji: all standing crops and defoliating fruit trees. (3) As they rise for flight from home onlj' in dry clear weather (when the prevailing winds are from the north or northwest), they do not seri ously invade the regions (mostly infertile) to the west of their home. (4) The invaders extend or may extend their tiights to a distance oti at least 500 miles from their jjoint of origin, but there is no ) They deposit their eggs throughout the invaded territory, but their descendants therein of the succeeding year not only do not effect a tithe of the damage of the i)receding year (although on the ground earlier), but when winged move about in swarms from place to idace, their i)revailing eaking. exceedingly few of the returning swarms ever reach the true home of the species. As a rule, they show signs of enfeeblement and deposit few eggs in the invaded region, so that their descendants on tht invaded soil grow less and less numerous, and, in eftect if not in fact, die out in the course of a very few. i)robably at most two or three, years. I can add almost nothing to the facts given by the Entomological Commission. It may be worth while to state that in 1S77 I took or noted tiiis insect at the following points; July 11. between Idaho aiid Georgetown, Colorado, common, both mature and immature: July 12-13.

I have also seen specimens fiom tiie fcdlowing localities, which have some special interest: Fort Hayes, ivansas, collected by J. A. Allen ia June. 1871 (not heretofore reported in Kansas in this year); Preston, Texas, Cajjtain Pope, ]May 1."), 1854 (uecessarily the i)rogf^nyof an invad- ing Hight in a previous year, and none are recorded either in Texas or Arkansas between 18r)0 and isr)3, inclusive); Ringgold P.arracks.

Schott, and San Lorenzo, Chihuahua, Mexico, F. Palmer, showing that it reaches Mexico, and that too even as far west as Sonora. I have also a single specimen from California from Mr. II. Kdwards, but it may have been taken in that part of the State east of the Sierra Nevada. A tabular view of *' locust vears''for the different States will be found in the lirst report of the Commission, page 113. This insect is normally single brooded; the eggs winter and the earliest (those in warm exposures) hatch in Texas from the middle to the last of March, and '• continue to hatch most numerously about four (lays later with each rary region" begin tVom tlie .Ith to the 10th of May in latitude 35^, and about four days hiter witli earh de^nee fartlier north.

In this group the antennae of the male are exceptionally long and the pro/ona is distinctly longitudinal. The interspace between the meso- sternal lobes in the same sex varies from subfjuadrate to half as long again as broad, while in the female it varies from distinctly transverse to much longer than broad. The pronotum is posteriorly truncate or subtruncate, usually broadly emarginate. The tegmina are not only abbreviate but rarely as long as the pronotum, lateral and distant. The hind femora are long, and the hind tibiae light colored, with eight to twelve, generally about ten, spines in the'outer series. The supraanal plate of the male is triangular and rather simple; the last dorsal segment is obliquely and deeply sulcate on either side of the base of the furcula, which consists of a pair of very slender parallel tiugers or spines of variable length, but never very long; the cerci rapidly narrow at the base to a long and exceedingly slender incurved blade, hardly as long as the supraanal plate, and narrower by far than 206 VlliJCEKDlSaS nr THE SAHOSJl JdCSKrM. vocxx. the frontal co.*ta; the Riil);:«'nital ]»late is Hniall and subcouicul or sub pyraiiiidaK thr inar^iiis lyiii;^: in one phme anng as the intraocular portion of the genae; antennae testaceous, apically iufuscated, less than two thirds (female) as h)ng as the hind femora.

The female, collected by Xantus (presumably at Cape St. Lucas), is the one referred to by me in my original description of M. cridus ;is belonging to that species, but it dift'ers from it (and agrees with M. hfonphreysii) in the emarginatiou of the posterior border of the ])ro- notuni, and difiers from both in the greater robustness of the body, especially in the metathoracic region. It is quite possible that the male and female here brought together do not properly belong to one species; there is great disparity in size and, as the description shows, some unusual disagreements between sexes of the same species; but they certainly belong in close proximity, even if distinct ; if they should prove di.stinct, the name should be retained for the male, from which the description (especially in colors) has principally been drawn.

In this group, composed of si)ecies mostly of small size, the prozona of the male varies from quadrate to distinctly lougitmliual, and the interspace between the mesosternal lobes of the same sex vaiics from a little longer than broad to more than twice as long as broa«l. Tl e antennae of the male are rarely as long as the hind femora. The teg niina are always abbreviate, about as long as the i)ronotuu), usually rather broad and either ungulate or nu)re or less acuminate at tip. The liind tibiae are red, rarely greenish, and have nine to sixteen, more com iDonly about eleven, spines in the outer series. The extremity of the male abdomen is usually very feebly <'lavatr, and tiie supraanal plate usually triangular and rather tlat ex(ei»t fortlie subnu'dian ridges; but it is sometimes long subclypeate with margins more or less raised; the furcula always consists of a feeble or ratlu-r feeble pair of denticulations; the cerci are generally rather small, some- times nearly equal, at others tapering more or less in the basal half, but rarely anywhere very slender, generally incurved or inbent, and occasionally somewhat arcuate as seen laterally, always well rounded apically and geuerally exteriorly sulcate on the apical half; the sub genital plate is broad, generally also short, subccmicalor ^ubpyramidal, the lateral and apical margins in the sauie i)lane and entire. The species are ti ve in number and have together a wide range, though all but one are rather local, so far as kuown. Tiie one which is widely distributed occurs from ]!!febraska and Kansas to Texas in the West. and from southern New England and central New York to Virginia in the East. The other species are knowu respectively from Lower Call fornia, Colorado, Idaho, and northern New England, but the last is also reported from Illinois. This series represents in brachypterous forms the glaucipes seiies in macropterous, and in an ideal arrangement the series should not be so widely separated as here. 41. MELANOPLUS SCUDDERI.

Extremity of male abdomen a little chivate, a little recurved, the snpraanal plate triangular, acutangulate at tip, with strongly elevated and sharp sub- median ridges on either side of the deep, narrow, and subequal median sulcus, which fades and widens apically; furcuhi consisting of the slightly tumid attingent jiortions of the mesially divided last dorsal segment, each produced posteriorly as a triangular tooth projecting over the supraaual plate, the tooth sonu'tinies shorter than, usually as long as, the basal swelling, in southern examples half as long again as it (the length slightly exaggerated in fig. 0); cen-i simi)le, feebly fal- ciform blades about twice as loiig as their basal breadth, at the rounded apex about half as broad as at base, usually slightly incurved, and generally exteriorly sulcate on the apical half\ sometimes to a considerable degree; subgenital plate small, runer), and, with doubt, by Thomas from Colorado "subalpine'' and southern Colorado. The si)ecies varies to a considerable degree, as appears in part from tlie above description. Texan specimens have the te«;:mina uniformly less acuminate apically and a longer furcula. Occasionally the tegmnia are considerably longer than the i)ronotum, as appears especially in a pair sent me by Professor 11. Garman from Kentucky. Specimens from southern New England appear uni/orraly somewhat smaller tlian others, while there is no difference in size between specimens from Maryland and Texas. Walsh, supposing the species here described as M. irtfhhii to be the true ^f. sciidderi, immed the present species in his letters rtzotittir nibricrus, and I still ])ossess several specimens sent me by him in 18(>.j under that name. Examination of the types of Tliler and Thonuis show that sciulderi and unicohr are identical, as McNeill thought. Kiiey states that this species attains nmturityin the vicinity of Saint 1 ouis, Missouri, about September 1, and begins to oviposit on Septcm bev 24. The eggs have a quadrilinear arrangement in the pod. Uliler found it abundant near Baltimore, Maryland, on *'the sides of higli hills," Beutenmiiller about New York City in "dry places," and Com- stock about Ithaca, New York, '*among scattered trees on the crests and slopes of our highest hills." In the West, however, Allen found it in Iowa "•common in grassy groves" and "on prairies," while McNeill says that in Illinois it "'is very frequently found along roadsides or in pastures," and in Indiana Blatchley finds it "in open woods and pastures." 42.

The hind margin of the pronotum is either truncate or very broadly obtusangulate. The tegmina are abbreviate and nearly as long as if not somewhat longer than the pronotum, some- times rounded and sometimes subacuminate ajucally. The hind tiojae are generally green, and the species vary much in the number of spines ill the outer series, ranging from nine to fifteen. The supraanal plate is triangular and generally rather tiat, the lateral margins hardly elevated; the furcula may be either reduced to slight jirominences or produced as delicate spines crossing the basal fourth of tlie supraanal plate; the cerci again vary considerably, being either stout, strongly constricted in the middle and widely expanded apically, or tapering to a half or two thirds the basal breadth and then forming a relatively slender, slightly decurved, compressed tinger; the subgeni- tal plate is narrower, generally considerably narrower, than long, with aiigulate, slightly elevated and tuberculate extremity. The species are rather slender, of about medium size, and are three in number.

It has also been reported by McNeill from McLean County, Illinois, and Monroe County, Indiana. This species is remarkable for the length of the antennae. It matures very early, McNeill having taken it as early as June 5 in Illinois, wherr he thinks it is the first Orthopteron to mature from eggs of the same season. Blatchley records it in Indiana even as early as May 11. McNeill says "it is by no means common, . . . being restricted to a few localities [about Moline]. It shows a decided preference for the sides o'' open, grassy ravines."' One specimen before me is marked by Blatchley as found in woods. The species has never before been described, but has been mentioned by Walsh's names in several publications; the specific name '' viridu lus'' used on one or two occasions was a misreading of Walsh's name ''viridicrus," and probably originally due to bad chirography on my part.

It tlieretore occurs in a broad belt along our northern border from the Atlantic nearly or quite to the J*acific. As seen in the above description, the species occurs in two forms, a moderately short-winged form, to which the name .1/.,/". curtua (J?late XVI II. figs. 2-3) maybe given (it was once described as curtHti)', and a very long and broad winged form, which may be called M.f. rolaticiLs (Plates I, tig. c; XVIII, tig. 4). The latter is known only from Michi- gan, and was brought to my attention by Professor P)runer. During a recent visit to London, 3Ir.

Flofrath r.runner writes rae that he pcissesses specimen-^; from Lalu'ador, Hudson Bay, and Valdivia. Chile. I can not fori>ear exjiresslng a doubt about the accuracy of this last locality. As MvlnuttjtJuH and Vinlixmti are the genera of Melanopli most abun dant in forms ami most widely spread, the former being especially true of MvlmtopUiH^ and as the present fcuin is the species of Mrlanoithis most nearly allied to Podisma, and, like most of the species of the latter genus, is peculiar to high latitiules or altitudes, it seems proper to regard M. hortalis as an archaic form. perha])s more nearly than any other resembling the original form frou) which the Melanopli as a whole have descended. Mr. Samuel Ilenshaw recently compared for me a female specimen of this species from Labrador with Walker's type of Calopienus arrtictis in the British Museum. He found tli^m to agree except in length ot wings, which in Walker's specimen, a uni(|ue, "extend sligiitly beyond the abdomen ;" the prosternal spine was the same. I have accordingly introduced it in the synonymy with a question mark; if it belongs her*' the range of the species should be extended to whatever point it Uiay have been in •• Arctic America" that Doctor llie collec^ted his specimei. The specimens which 1 have seen were taken by Mr. Sornbergcr August 15-U» at ths Es(|uimau\ village of Bama. He tells me that they were all taken on the banks of a mountain brook fed by the nudt- ing snows of the sutnmit near by. They were most abundant where tlie vegetation was most luxuriant at the bo:dersof the brook; noiu' were found below an elevation of 200 feet no)- above l.oOO feet, at whidi altitude herbaceous ]»lants became few and scattering. Mr. Sornbcr- ger can not say upon what it fed. but it was not found on any of the shrubby i>lanls common there — Betula. Vaccinium, Ledum. Salix.

This is a dominant and homogeneous group of medium or ratl'er small - sized species, in which the male prozona varies from slightly transverse to slightly longitudinal, and the interspace between the mesosternal lobes in the same sex is as in the spretus series. The tegmina are always fully developed or a little abbreviated (so as to fall a little short of the tip of the hind femora), immaculate or slightly maculate along the middle line. The hind tibiae are normally red and have ten ti> fourteen spines in the outer series. The supraanal plate is clyj^eate, longer than broad and mesially con- st licted. The furcula consists of a pair of parallel or nearly parallel, long or moderately long, generally separated, slender, tapering, sub- cylindrical fingers or spines.

The subgeuital plate is peculiar for beinj; very broad at base and narrowing so as to be at apex only about half as broad as at base (which does not show in the tlgures), the wliole lower margin nearly straight while the u})per is sinuous, the apical margin not elevated, entire (in one species very broadly and shallowly emarginate, or rather laterally tuberculate) and, as viewed above, broadly rounded. The species, five m number, are spread all over the continent from Atlantic to Pacific, from central Labratlor ^o central Florida, and from central Alaska, the ]\rackenzie River and Hudson Bay to Texas and central Mexico; they also extend to high altitudes above the forest line. No other series of ]\Ielanoplus has quite so wide an area of distribution, the bivittatus series, however, approaching it closely. 8i. MELANOPLUS PLUMBEUS. (Plate XVIII, fi};. 8.)

Si)ecimens from Florida which I formerly referred to this species probably belong to the next. It t)ierefore appears to inhabit the entire United States and tht set- tled parts of Canada, excepting only Alaska and also the southeastern United States (where it is replaced by the next species), and occurs south of our border as far as central Mexico. The species described by me as M. interior vf an, based upon specimens from Utah and other parts of the interior of the western country, which seem to differ from those found elsewhere in having cerci which taper more gradually and show less contrast in the width of the basal and apical halves, and at tip are blunter and less manifestly truncate, in which also tlie forks of the furcula are relatively longer and more strictly parallel, the tegmina rather shorter and generally lacking any maculatiou v tmte\er; the prosternal spine also is more frequently com- pressed before the tumid tip; but on comparing a large series of speci- mens from these western regions I tind it impossible to draw any line of demarcation, some specimens having some but not other of these characteristics, so that I can only regard the species as in a state of tiux in this region, preparing, as it were, to divide into distinct races not yet clearly enough defined to distinguish them. ' The first three references are doubtful ; they probaMy belong to M. extremum. 2S4 PROCEEIHyaS OF THE SATIOSAL MUSEUM. tolxx.

In llayden's report on the survey of Nebraska (1872), I collected several accounts, printeil and unpublished, of the injury to crops attrib- uted to this s])ecies in the eastern Cnited States. As up to that time ]\1. athtnis had not been distinguished from M./viuur ruhrum, it is pos- sible, and I am now inclined to think it probable, that all the serious injury d(me to crops in the East is done by M. atlonis; for although almost everywhere less common than M . femur-rnhrum ^ M. athinls has been shown to have the cai)acity for immense multijdication, and has been directly i)roved to be the culprit in some instances; as it is also much more closelj' and indeed very closely related to the destructive locust of the West, .1/. aprctux, it is far more likely to have been the actual pest in all the records of the past. At least until direc*: provable charges are made against it, .1/. Jemurrubrum should be looked upon as less injurious than M. atlanis; it is especially doubtful whether it ever migrates in aerial swarms; as a general rule the tegmina and wings are longer in ^1/. athniits than in M.fi'mur-rubnnn^ though both species vary considerably and intergrade in that particular. From measurements made on Mis-souri specimens, IJiley found that the teg- mina in the present species extended beyond the abdomen as follows: In 28 males, 0-2 mm., average, 0.8 mm.; in 54 females, 0-3 mm., aver- age, 1.1 mm. Bruner excellently expresses the fact when he says that the imme- diate distribution of this insect "appears to be controUetl altogether by climatic conditions, the chief of which is the i)reseuce of a certain amount of humidity. . . . It is a frequenter of low grounds, culti- vated fields, shady margins of Avoods, etc., where vegetation is rank and tender.'' It is rarely found upon dry hillsides when meadows close at hand may swarm with them, while the opposite is true of other species, J/, coll inns for instance; yet such specimens as do so occur will be found to differ from those inhabiting more favored localities, in being lighter colored and more uniformly grayish in tone, with slighter con- trasts; those from drier stations appear also to have on the average rather shorter wings.

At Andover, Massachusetts, on October "» many years ago I observed a pair of this species, male and female, near together alternately sig- naling to each other with a slight <|uick niovenuMit of the hind legs ui)on the tegmina, as if stridulating. I made no note of whether any sound was actually produced and do not now recall any.

It has also been reported from (Quebec (Provancher, Scudder; Dodge County, Nebraska (Dodge), and the Mackenzie River, British America, at latitude 05° (KirLy); the last, however, is uncertain, dependingon the determination of Kiiby's species. It probably occurs throughout the larger part ol Canada and the northernmost United States. As indicated in the deseiiption, this insect appears in two forms: a short winged (J/. e.jiiniuH), in which the tegmina at rest do not reach the tips of the hind i*emora: and a long-winged (for which 1 propose the name M. e. ncandens), in whu;h Ihey surpass them, generally con- siderably. The latter has also a slightly slenderer body, though the difference is not marked. It appeals to affect high latitudes and alti- tudes, being found in all the localities in the high north where Kennicott collected, on the Big Horn Mountains in W^yoming. and on the summits of Greylock in Massachusetts, and the White Mountains in New Hamp- shire, in all of which (unless in Wyoming, wlir:ice I have only seen two specimens) it is the prevailing or exclusive form. The short-winged form, however, occurs in all these places excepting the Aljnne region of the White Mountains, where it has not been taken ; and the long winged occurs also at lower levels in New England, as at North Conway, New Hampshire, Jay and Montgomery, Vermont, and Winchendon, Massa- chusetts, but it is only found in these places exceptionally, to judge bom the specimens seen. The two specimens from the Big Horn Mountains, the male scandens^ the female Junius, are of exceptional size, and Arctic American specimens are also distinctly larger thaiL those from New England or Nebraska.

It will probably be iini)ossible ever to detenniiie detinitely Kirby's Loritata leucofftoma, as the description is altogether inadequate and the British Museuiu does not contain the type; at least I could not find it by special search for it in 1865, and it is not mentioned in Walker's catalofjfues; Walker, foHowing mj' earlier but probably wrong determi- nation, i)laced it as a synonym of M. biviitatuSj but none of his sj)eci- mens included Kirby's. ^ Mr. Samuel Ilenshaw, during a recent visit to the British Museum, examined the types of Walker's (JaloptenuH ej-t rem its and found tiiem to agree with si)ecimens of the present species coming from Kennicott's collection on the upper Mackenzie, which he took with him; they differed "only in having slightly shorter wings," in which respect Walker's specimens agree with others of Kennicott's collection belonging to this species. . 85.

The supraaual plate is generally rather simple, triaiijiular with convex sides and a generally produced apex, but is sometimes strongly and abruptly compressed apically. The tiircula is develojied to an extreme as a pair of parallel, flattened, pointed plates, usually more than half as h)ng as the supraanal ])late. Tlie cerci are rather slender or only moderately broad, apically spatulate or subspatulate, incurved or inbent, of variable length relative to tiie supraanal plate. The sub- genitrl plate is moderately broad apically, but distinctly narrower than long, the apical margin entire and not elevated, or only slightly elevated. v The species, sis in number, are of medium or slightly above the medium size and with the exception of the typical spe<;ies are found only in the extreme Southwestern States — Southern California, Arizona, and Texas, a'ld in Lower California and Sonora, but the typical species extends the range on the north to Washington, Idaho, and Wyoming, and eastward to Louisiana and western Nebraska. It is a western type. 86. MELANOPLUS BISPINOSUS, new species. (I'lateXIX, fij;. 6.) Cinereo-fuscous, more or less ferruginous.

This has also been noticed by liruner, who remarks that the resemblance extends to the earlier stajres of the insect. Coquillett remarks upon the ease of its tiijjht, describing it as in a straight line, for a distance of from 5 to 20 feet from the ground. He found it devouring the ripe kernels of rye in Calitbrnia, and Riley reports it as injuring cotton in Louisiana. Coquillett regards it as a migrating species, but his specitic statements refer only to short flights from the fields to the tree tops or the reverse, fifty to one hundred yards being the usual distance. In the San Joaquin Valley he found specimens pairing at the last of July. go. MELANOPLUS COMPLANATIPES, new species. --^--^ - = (Plate XIX, fig. 10.) Nearly uniform light testaceous.

It has also been reported from (lanlen City, Kansas (Bruner), Ke^Ljina, Assiniboia (Caultield), and northern Calitbrnia, abundant (Koebele). This species bears a close general leseiiiblance to M. birittatux, from which it is nevertheless very distinct. Bruner says, with regard to it, that *'it never leaves the open country for tind)eied or low localities where the vegetation is rank," as that and other species do. It is a prairie species. Coekerell has given the variety with red hind tibiae a distinctive name. 1 have seen it from British Columbia, Washington, Oregon, northern California, Idaho, Montana, Nebraska, Kansns,Utah, Nevada, Colorado, and New Mexico. It appears to be the luevailing if not exclu- sive form in some northern parts of its range. Specimens before me from Wyoming, Iowa, and Texas have blue legs only; both forms occur in Montana, Nebraska, Ctah, and Colorado. In coloring and markings it is one of the most variable species of Melanoplus known to me, but 1 have been unable to find grounds for specific distinctions between the various forms, which seem to run into each other completely. 97.

Bruner reports it from oak groves and Smith on cranberry bogs, but Beutenmiiller has found that it lives on pine trees. Blatchlej' found it in the depths of a tamarack swamp, and says it is not an active insect, "usually, after one or two short leaps, sciuatting close to the earth, and seemingly depending upon the close similarity of its hues to the gray- ish lichens about it to avoid detection."

Head above, behind the narrowest i)art of the vertex, marked with an elo'igated, expanding, blackish fuscous stripe, through the middle of which runs a yellow line, and by a supraorbital arcuate band of a simi- lar color, usually broken, often obsolete, and terminating just below a narrow short yellow stripe behind the upper iiart of the eye; space between the eyes rather narrower than the frontal costa, the fastigiuni broadening considerably in front of the eyes and broadly sulcata throughout; frontal costa broad and nearly efjual, broadest just above the ocellus, rather sparsely punctate, and at the ocellus very shallowly sulcate, often nearly imperceptible.

Thomas's specimen was derived from Crotch's collection in the Museum of Comparative Zoology; Crotch collected OedaleouotKft enigma coUaris in central, not southern, California, whereas Tho.ias gave his C. JiavolineatuK from southern California. Thomas's description does not at all tit any species from southern California which has come under my notice, and until such a form occurs his name should go for nothing — at least until the Acridian fauna of that region is fairly well known. 1 Bull.

The two males weredilierent species, one being Melanoplus feuioratun, theother (Illinois) distinct, but allied to it by the cerci, though with short tegmina (probably Milnnoplug viola). It was further doubtful whether the female belonged witli either of the males. Certainly, then, we shall be obliged to consign Walker's species to merited oblivion.
