ORTHOPTERA— ACRIDIDAB— G. CARPENTERII. 871 



on each elytron, extending- from the base to the apex, widening toward the 

 apex. Wings black, or very dark fuscous ; this color being almost uniform 

 throughout. Posterior femora ferruginous, except the disk, which is occupied 

 by a dark-fuscous or black stripe. Venter yellowish ; sternum rufous. 



8 . — Length to tip of abdomen, 1.10 inches ; elytra, 0.75 inch ; posterior 

 femora, 0.62 inch ; posterior tibise, 0.62 inch.

The present species is evidently closely allied to S. leucocerca, as is 

 indicated by the color of the wings, and form of the subgenital plate of 

 the male ; but leucocerca has the posterior lobe of the pronotum roughly 

 punctate, which clearly distinguishes it from our species. The want of 

 this last character would possibly exclude it from Stal's genus as now 

 restricted, yet the other characters are so clearly and distinctly marked 

 that I have no hesitancy in placing it here, although this may necessitate 

 the dropping of this character from the generic distinctions.

Stal has described this under the name Truxalis angusticomis (Recensio, 

 105) as a new species. His specimen was from Carolina.

I find a few specimens of this singular species in the last collection. 

 Although there is nothing accompanying the collection to indicate the exact 

 locality where, or altitude at which, it was found, yet, as it is a true montane 

 species, I presume it was obtained in the mountains of Northern New 

 Mexico or more probably of Southern Colorado. I have also received a 

 large number of specimens from Mr. Putnam, of Iowa, chiefly males. In 

 this collection I find not only the male, but also some specimens which I 

 feel quite well satisfied are the females of this species ; but as they vary 

 somewhat I will give a short description of one of the best specimens
