Descrlpt'ion. — In general structure nearest to T. 

 iiiexlc(mn» Saussure, but differing from that insect 

 in its somewhat slenderer form, less strongly 

 granulous head and thorax, in the more elongate 

 and angulate pronotum, the longer and narrower 

 antennas the plain unhanded hind tibiae and 

 hind femora, and in being of a uniform ferrugi- 

 nous color throughout instead of having the 

 tegmina and body mottled ai;d marbled with 

 fuscous. The present species also differs from 

 the insect with which it has been compared in 

 having the wings tile red instead of rose color 

 and the margin along with the shorter and less 

 conspicuous tienia smoky brown instead of fulig- 

 inous. Its hind tibiie vary from pale greenish 

 yellow, female, to glaucus, male, while in mexi- 

 canus these members are pale and dark banded 

 as in Spharagemou haUi. 



Length of body, male 20 nun., female 32 mm.; 

 pronotum, male 6.5 nmi., female 8.5 mm.; an- 

 tennae, male 8 mm., female 10.5 mm.; tegmina, 

 male 20.5 mm., female 28 mm.; hind femora, 

 male 13 mm., female 17 mm.
