frontal coata equal, rather deeply snlcate below the ocellns ; anteTinae 

 li"^]it brown, the basal joint unusually small. Pronotum small, equal, 

 compressed, the dorsum flat, the whole so much smaller than the head 

 as to jjive the insect a strangulated ap]>earance, brownish green, mot- 

 tle<i with darker and lighter markings, the lateral carinae with a yel- 

 lowish stripe and the lateral lobes with a similar obliijuc stripe 

 descending to the lower anterior angle; the metazona is profusely 

 jmnctate, the transverse sulci deei)ly impresvsed, the median carinae 

 obsolescent, the lateral carinae wholly obtuse, the posterior margin 

 very obtusely angulate. l*rosternal spine not very stout, cylindrical, 

 very bluntly tipped, inclined rather strongly backward. Tegmina 

 about as long as the pronotum, slender, short, lanceolate; wings rudi- 

 iiientary. Hind femora slender, yellow, tinged on tlie upper half with 

 bi-owiiish, and obscurely, nan-owly and transversely bifasciate above 

 with the same; hind tibiae glaucous ( ?),the spines reddish, tipped with 

 Idack; arolium extremely large. Abdomen yellowish, tinged above 

 with greenish brown, the last segment of the male scarcely upturned. 

 Sni)raanal plate of male broad triangular, with a deep ])ercurrent 

 median sulcus, the margins of which are strongly elevated in the basal 

 half, gently elevated in the apical half, the apex slightly less than rec- 

 Tiingulate, blunt; furcula consisting of a pair of minute, rounded, 

 slightly i)rojecting, adjacent lobes; cerci (compressed laminate, scarcely 

 reaching the tip of the supraanal plate, gently incurved, tapering on 

 the basal half, scarcely enlarging beyond, where it is more than half as 

 broad as at the base, the tip broadly rounded, but slightly produced 

 below.

 tniiitly arched, not raised above the pronotum; fastigium rather nar- 

 low but greatly l>roadening anteriorly, very little declivent, shallowly 

 silicate; frontal costa about as broad as the interspace between the

 eyes large and very prominent, rather broad oval, about half as long 

 ;ij;ain as broad, separated above by a moderate interval; antennae 

 slender, slightly depressed. Pronotum moderately long, equal, com-
