TTead somewhat proinineiit, lijjlit fusco-olivaceons. with a broad^ 

 piceous, postoenlar bund, and above more or less iiituscaled or dulled 

 in e«>lor, <^»ften with a i>airof lon<;itudinal fuscous stripes; vertex rather 

 tumid, raised considerably above the level of the pronotuni, the inter- 

 space between the eyes half as broad apiin (inale) or fully twice as 

 broad (fenuile) as the tirst antennal Joint; fasti^iuni steeply declivent, 

 rather deeply (inalo or shallowly (female) sulcatc throngh<mt; frontal 

 eosta moderately prominent, di- tinctly failing to reaeh the clyj>eus, 

 slightly narrowed above, especially in the male, about as broad as the 

 interspace between the eyes, feebly and broadly sulcate at and below 

 the ocellus, feebly |)unctate. above biseriately: eyes not very large 

 nor very prominent, not more so in the male than in the female (unus- 

 ual in Melanoplusj, sliglitly shorter than the intraocular portion of the 

 genae; antennae testaceous, nearly two-thirds as long as the hind femora 

 in both sexes, scarceh' relatively shorter in the female than in the male. 

 Pronotuni very short, equal on the prozona, expanding somewhat on 

 the meta/.oim, light brownish fuscous, often ferruginous, the lateral 

 h>bes with a much broken and maculate postocular piceous or dark 

 fuscous band contined to the prozona, the disk broadly convex, passing 

 into the vertical lateral lobes l)y a rouude<l angle forming a blunt 

 shoulder on the metazona and ])osterior section of the i)rozona only; 

 median carina distinct and antero-posteriorly convex on the metazona, 

 feeble and often subobsolete on the prozona; front margin truncate, 

 hind margin feebly obtusangulate, the angle sometimes rounded: j)ro- 

 zona distinctly transverse, more so in the female than in the male, 

 shorter (]Kirticularly in the female) than the tinely and very feebly 

 punctate metazona. I'rosternal spine rather long, a])pressed. feebly 

 conical, very blunt, erect, shorter in the female than in the male; inter- 

 space between mesosternal lobes from half as long again to twicte as 

 long as broad (male i or (juadrate i female). Tegmina exceptionally long, 

 far snr])assing the hind femora, not very narrow, subequal, brownish 

 testaceous, heavily tlecked with blackish fuscous, usually through tlie 

 discoidal area but sometimes contined to the middle line; wings ample, 

 hyaline, the veins mostly fusc()us, but testaceous next the costal margin. 

 Fore and middle femora only a little tumid in the male: hind femora 

 testaceo-ferruginous clouded with fuscous above, particularly in broad 

 basal, premedian and pnstmediau patches, the geniculation mostly 

 blackish fuscous, the lower genicular lobe pallid testaceous with a basal 

 blackish bar, the inferior surfiice, especially externally, flushed witii 

 roseate; hind tibiae bright red throughout, the spines black almost to 

 the very base, ten to eleven, rarely twelve, in number in the outer series. 

 Extremity of male abdomen a little clavate, somewhat recurved, the 

 supraanal plate triangular or sabhastate, faintly compressed just 

 beyond the middle, the margins feebly elevated on basal half, the apex 

 subacutangulate.the median carina percurrent and rather deep, between 

 rather high and sharp ridges; furcula consisting of a pair of slight.
