side near the tip; ovipositor somewhat shorter than, or about as long- 

 as, the posterior femora, curved slightly downward. 



Ti/pe. — Locasta fulujhumi Thomas. 



This g-enus is closely allied to the long'-winged forms of the old 

 world genus Dyrinadnm^ but the more slender posterior femora, nar- 

 rower tegmina, more slender form, and the presence of distinct lateral 

 carinas on the posterior portion of the pronotum will serve to sepa- 

 rate it from that genus. 



The species of CapDohotes are probably all nocturnal, living among 

 low, stunted vegetation. The notes given under C. occidental /'s will 

 pi-ol)ably be found to be true of all the species of the genus. 



Three species and two varieties of Capnohoies are recognized and 

 may be separated l)y the following table: 



KEY TO THE Sl'ECIES OF CAPNOBOTES. 



A. Elytra marked along the disk with oblique light-colored spots and apically 



Ijroad, 5 mm. from the tip being distinctly more than one-half as broad as at 



the broadest point (fig. 20). 



B. Larger. Wings deeply fuliginous. Cerci of the male six or seven times as 



long as the basal breadth and armed on the inner side with an apical and a 



subapical tooth, subequal in size (fig. 22) faliginosus, p. 311 



B^. Smaller. Wings hyaline, or slightly fuliginous in the costal area. Cerci of 

 the male about four times as long as the basal breadth and armed on the 

 inner side with a short, blunt apical tooth, sometimes reduced to a mere 

 shoulder, and a longer subapical tooth (fig. 23). 



C. Color brown or fawn colored .occidental i.^, p. 315 



C. Color green or greenish. 



D. Elytra uniformally green occidental is var. uniform is, p. 317 



D'. Elytra green, with a row of light-colored discal spots. 



occidentalis var. viridis, p. 316 



A''. Elytra nearly uniformly brown and apically very narrow, 5 mm. from the tip 



being considerably less than one-half as broad as at the broadest point

Description. — Head moderate, scarcelv broader than the anterior 

 portion of the pronotum into which it is inserted quite deeply; fas- 

 tigium narrow, about as broad as the basal joint of the antenna, mod- 

 erateh" prominent and very shallowly sulcate above; eyes moder- 

 ately large and (juite prominent, a little longer than ])road; antenna? 

 long and slender, the basal segment large, subquadrate. Pronotum
