Allied to //. abbrcvidta Brunor from Cucrnavaca, JMorclos,-^ but 

 dift'ering in the much longer tegmina and wings, the latter extending 

 beyond the former, the well-defined humeral sinus of the lateral lobes 

 of the pronotum and the more arcuate ventral margin of the same 

 parts, the more recurved tips of the male cerci and the truncate sub- 

 genital plate of the same sex (this has distinct lateral angles and a 

 very well-developed median protuberance in abbreviata). The form of 

 the pronotum is very similar to that of abbreviata, and in this respect 

 these species stand apart in the genus from the others which possess 

 sharp lateral angles. 



Size medium; form moderately compressed and elongate. Head 

 with the occiput moderately globose, not elevated above the pronotum 

 and regularly declivent to the narrow, compressed fastigium, which is 

 truncate distad, subequal in the distal half and with distinct lateral

carina, contiguous to the trigonal facial fastigium; eyes rather small, 

 elliptical and prominent for their size; antennae with the proximal joint 

 subtrigonal in section, in length slightly more than twice that of the 

 tegmina. Pronotum with the dorsum deplanate, lateral angles sharp
