REVISION OF THE MELANOPLI—SCUDDEH. 49 



itclv retreiitiiij;; interspace between the eyes rather broad (male) or 

 )road (female), the fastigiiiin feebly if at all silicate, the frontal costa 

 listinctly broadest between the antennae, where it is nearly as wide as 

 male) or still much narrower than (female) the interspace between the 

 •ves, percnrrent, suleate at least below the ocellus; eyes not very 

 prominent nor very larjje, lon;j:er in proportion to breadth in the female 

 [han in tiie male, and yet in the female hardly, in the male distinctly, 

 longer than the anterior infraocular portion of the genae; antennae 

 latlicr coarse, more than half as long as the body in the male, distinctly 

 longer than head and pronotum together in the female. Pronotnm sub- 

 LMjual (male) or distinctly and very gradually broadening i)ost. riorly 

 female^ with a rather slight median carina, sometimes interrupted 

 between the sulci, the disk very broadly subtectate. passing by a rounded 

 mgle, without forming lateral carinae, into the vertical (female) or sub- 

 vertical (nude) lateral lobes, the front marg'ii subtiuncate, in no way 

 haring, the hind margin obtusely angulate, the impunctate or very fee- 

 bly rugulose prozona nearly or quite half as long again as the i)unctate 

 i>r distinctly rugulose metazona, its transverse sulci moderately dis- 

 tinct, that in the middle straight, and followed a tb.ird of the way to 

 tlie metazona by a similar but arcuate sulcus. Prosternal spine blunt 

 conico-cylindrical, more or less retrorse; interspace between mesoster- 

 iial lobes nearly twice as long (male) or half as long again (female) as 

 broad, the inner margins of the lobes nearly straight: metasternal 

 lobes aitingent (male) or suoattingent (female). Te^mina abbreviated, 

 generally but not always a little longer than the i)ronotum, rounded or 

 subacumiuate at tip, their inner margins ()verlapi)ing or separated. 

 Foie and middle femora distinctly gibbous in the male: hind femora 

 variable, as also the coloring of the nferior genicular lobe: hind tibiae 

 witli nine to ten, generally nine, spin ?s in the outer series. Abdomen 

 of male very feebly clavate, very feebly upturned, the lateral margins 

 of the subgenital plate not ampliate at the base, the a)>e\' bluntly 

 aiiiiulate at tip, with a distinct but not very large tubercle, extending 

 beyond the inner si<lc of the apical margin ; furcula consisting of a pair 

 of slight, rounded, feebly projecting lobes. 



This genus is closely aUied to Hypoehhira^ but is composed of gener- 

 ally stouter forms, in which the antennae are longer, the pronotum is 

 Qsually rugulose rather than punctate, and the males of which have 

 iioie tumid anterior femora, besides the ditferences pointed out in our 

 ;;»l)le of genera. 



r. ((rKtipcn)tis may be taken as the type. 



The genus occurs only in the West, where it ranges east of the Kocky 

 MMiiiitains from Nebraska to Texas, and occurs again in Duraugo, 

 T'xico. _ _ ..
