Size slightly smaller, proportions much as in the female. The 

 tegmina are translucent, and when in repose the dorsal fields are 

 quadrate in outline, with the caudal margin broadly arcuato-truncate. 

 Subgenital plate as in fasciatus. Proximo-internal spine of caudal 

 tibia as described under Morphological Notes in the generic discussion 

 of the present paper.

As in other characters, there is very much less variation in the 

 size and proportions of the present species than in fasciatus. In the 

 entire series before us there are no specimens noticeably larger or 

 smaller than those whose measurements are given above. 



Color Notes. — The specimens here described are typical in colora- 

 tion of the great majority of specimens of the species before us. 

 General color bistre with a tawny suffusion, the dorsum of the 

 pronotum dotted, and the caudal limbs mottled with darker brown. 

 Head with a narrow pale yellowish line about the eyes except on the 

 infra-ocular portion of the gense, a medio-longitudinal line of the 

 same color faintly indicated on the occiput. Maxillary palpi, of 

 male with proximal portion of penultimate segment pale, of female 

 with penultimate segment and proximal portion of terminal segment
