PROCEEDINGS OF THE ACADEMY OF [May-Oct., 



narrowly truncate mesad, broadly oblique truncate laterad, lateral 

 margins truncate, distinctly converging ventrad, ventral margin 

 decidedly arcuate-emarginate ; eyes slightly more prominent than 

 in the female; antennae lacking. 



Pronotum very slender, its greatest width across the expansion 

 contained more than five times in the length of the same, general 

 form much as in the male, but the form of the inflation is more 

 decided and the shaft is more strongly triquetrous, with the median 

 carina decidedly indicated and the collar margins more subparallel; 

 lateral margins very weakly crenulate, this more evident, though 

 there far from decided, on the supra-coxal inflation. Tegmina 

 missing. Wings two and one-fourth times as long as the pronotum, 

 apices rotundato-rectangulate, these less coriaceous and less sharply 

 differentiated than in the female. Abdomen with the apex missing. 



Cephahc coxae with a single series of well-spaced spines; cephalic 

 femora about five-eighths as long as the pronotum, armed as in 

 the female; cephalic tibiae with one spine less on each margin than 

 in the female. Caudal limbs missing. 



Coloration of type and allotype have been completely destroyed 

 by immersion in a liquid preservative, from which they were mounted. 

 At present both specimens are ochraceous or brownish, with the eyes 

 walnut brown. The wings of the male are hyaline with the tips 

 brownish in the coriaceous section; the wings of the female are 

 hyaline tessellate with yellow, which colors the vicinity of the cross- 

 veins, the coriaceous section of the apices of the general tone. The 

 tegmina of the female show sufficient contrast to warrant the as- 

 sumption that the marginal field and probably a portion of the 

 proximal section of the discoidal field were originally purplish or 

 brownish, while the remainder of the discoidal and the anal fields 

 were greenish or yellowish, the hyaline areas moderately contrasted.
