Cycloptilus borealis n. sp. — Head and pronotum of both sexes, 

 together with the two basal abdominal segments of the female, light

 posterior femora not very much inflated. Anal cerci of the female a little 

 more than half as long as the body, quite stout and somewhat hairy ; 

 those of the male shorter and slenderer ; those of the female directed 

 backward, those of the male considerably divergent. 



Length of body, ^ and ?, 7.5-8 mm.; of pronotum, ^, 2.15 mm.;

This active little cricket was first taken by me on the loth of August, 

 1888, at Valentine, near the Niobrara river. It was found among dead 

 grass upon sandy soil on a south hill-slope. It was again met with on the 

 margins of the large salt basin west of Lincoln on the 15th of the follow- 

 ing month. These latter specimens were under boards lying upon sandy 

 soil. Judging from the fact that all the specimens thus far taken have 

 been found upon sandy soil, it will be safe to call it a frequenter of sand 

 districts, where it may be looked for under boards, loose stones, sticks and 

 loose debris of all kinds during daytime. 



Tow other representatives of the genus have been described from 

 North American localities, /. e., Cycloptilus squamosus Scudder, a Texan 

 species, and Cycl. Americanus Saussure, a Cuban species. 



LOCUSTIDiE. 



Ceuthophilus pallescensvv. %-^.—^\i\%\i'vi\^t%^ cricket is very similar 

 in appearance to C. pallidus Thos., but differs from that species in its 

 markings and in the number and arrangement of the femoral and tibial 

 spines. In size it is similar to C. maculatus, than which it is slightly less 

 arched.
