 across the very insignificant median carina, the last one situated 

 considerably behind the middle; anterior edge collared, broadly 

 rounded on occiput, the hind edge of disk obtusangulate, the lateral 

 lobes higher than long. Tegmina rather strongly, profusely and 

 regularly veined except on basai half of dorsal field where they are 

 irregulär, gradually and quite evenly tapering from the base to the 

 acuminate apex, considerably surpassing both the tip of the abdo- 

 men and the hind thighs: wings small, narrow, much shorter than 

 the tegmina and with the costal field narrow, pointed and very 

 noticeably longer than the anal field which has the margin undu- 

 late; the veins rather few, irregulär and interrupted or missing on 

 the basai half. Hind femora robust basally, graceful before the 

 genicular area, the lobes of the latter rounded below, the apex 

 angulate, subacuminate; hind tit)iae fairly robust, somewhat hirsute 

 and provided with seven blacktip])ed spines externally and eight

 directed gently to the front. Mesosternal lobes sejjai-ated by a sub- 

 quadrate space nearly as broad as the lobes themselves, the inner 

 edges of the latter rounded; metasteinal lobes approaching much 

 more closely, the interval narrowing fully one-half to the rear. Valves 

 of the ovipositor normal. 



General color pale brunueo-testaceous with an olivaceous tinge

 pleura and hind lobe of the ijronotiim. Tegmina with tlieir disk and 

 the costal field on the apical two-thirds black, the dorsal or poste- 

 rior field pale testaceous, wings infuscated, most strongly so along
