The female is larger and bulkier than the male, but is otherwise very 

 similar. The supra-anal plate of the female is transverse, rounded and 

 with a moderately deep V-shaped median emargination, the cerci are 

 about equal to the supra-anal plate in length, subequal in the proximal 

 half, tapering in the distal half, supra-anal plate large, moderately 

 inflated, cereal sinuations slight, the apical margin arcuate.

Three males, one female. 



The female is slightly larger than the type specimen, but otherwise 

 the series is perfectly typical of the species. 



The supra-anal plate of the male is rather produced, trigonal and 

 fissate mesacl with the incision a mere slit to very near the apex; cerci 

 about half again the length of the subgenital plate, tapering in the distal 

 two-thirds; subgenital plate not reaching the caudal margin of the 

 supra-anal plate, trigonal, supplied with lateral styles nearly a third 

 the length of the cerci. 



Measurements of Male. 



Length of body, 22.5 mm. 



Length of pronotum, 5.5 '' 



Greatest width of pronotum, 6.5 '' 



Length of tegmen, 21.2 " 



Greatest width of tegmen, 6 "

One male, one female. 



The base color of these specimens is maize yellow, and between the 

 eyes the head bears dorsad a pair of tapering spots of mummy brown, ■ 

 ventrad a blotch of seal brown, which has laterad short bars of the 

 same color extending ventrad between the antennae. The pronotum 

 is very finely sprinkled with, and the delicate pattern traced, in vandyke 

 brown, while the tegmina have the discoidal and anal areas very thickly 

 flecked with large and small spots of burnt umber, the basal and costal 

 regions being comparatively clear with only small spots.
