inferior margin ; frontal costa rather narrow, subequal but slightly com- 

 pressed above, obsolete below, more or less but generally feebly sulcate ; 

 antennae testaceous, infuscated except near base, of unusual length though 

 not quite so long as the long hind femora. Pronotum testaceous, the 

 disk somewhat infuscated, considerably constricted mesially, the lateral 

 lobes with a large and distinct, quadrate, subcentral but superior, fuscous 

 patch, the metazona plane, the hind margin subtruncate but feebly angu- 

 late, the median carina distinct, equal, percurrent, the lateral carinas blunt 

 and obscure except where marked with pale testaceous, strongly diver- 

 gent in front and behind. Tegmiua short and well rounded, when closed 

 not nearly covering the abdomen, testaceous, sometimes feebly infuscated 

 or minutely and obscurely flecked with fuscous ; wings hyaline with 

 glaucous veins. Hind femora of unusual length, much surpassing the 

 abdomen, testaceous, obliquely biannulate with blackish fuscous, the 

 geniculation broadly black; hind tibia? glaucous, basally pallescent.

I have based this species upon the male specimens just quoted, but I 

 have also three females from Lakin and Pueblo, with short wings and 

 long hind femora, which I think belong here, but which resemble 

 A. eUiotti more than do the males. The species is smaller than any of 

 its congeners, with shorter wings, longer hind femora, and subtruncate 

 posterior margin of the pronotum.
