positor jaws of the female placed well under the projecting 

 supra-anal plate. Cephalic and median limbs very small; 

 caudal femora reaching to the fifth abdominal segment, very 

 slender, tapering; caudal tibiae equal to the femora in length, 

 armed on the external margin with fourteen to sixteen small 

 spines. 



General colors of female burnt carmine and apple green, 

 the venter of the body and head ochraceous, the carmine 

 strongest on the dorsum, the green only on the limbs; caudal

 mersion in liquid preservative.

A single pair have been examined. Doctor McClung, of the 

 University of Kansas, who has studied the spermatogenesis 

 of this species and whose assistants collected specimens under 

 Professor Snow, informs me that "specimens such as those you 

 have were constantly caught in copulo, and a microscopical ex- 

 amination of the testes shows the spermatozoa well developed." 

 The specimens in hand have the tegmina and wing pads in the 

 reversed nymphal condition.

 1907. F. H. Snow. One male, four females. 



One of the females in this series is in a greenish phase of 

 coloration, while two of the remaining females have a pattern 

 of chiefly solid contrasting colors. The green phase has the 

 greater part of the head, dorsal half of the lateral lobes of the 

 pronotum, the pale stripe on the tegmina and the dorsal face 

 of the caudal femora apple green, while the strongly contrasted 

 phase has broad seal brown postocular bars extending over the 

 head and pronotum and regularly expanding in width, the 

 dorsal aspect much lighter, either ochraceous or rust red, and 

 the usual dark portions of the tegmina also seal brown. The 

 supplementary carinas of the pronotum are distinctly but not 

 strongly indicated in two of the females, represented by the
