center and a pair near the base, light brown. Pronotum with six faint 

 longitudinal stripes, the median ones extending across the scutellum. 

 Elytra subhyaline, nervures white, frequently margined with brown, es- 

 pecially the anterior margin of the reflexed veinlets, and with black 

 spots near middle of clavus, on the first cross vein of sectors and in third 

 apical cell. Face fuscous above, shading gradually to light below. 



External genitalia: Female, last ventral segment twice as long as 

 preceding, strongly narrowed posteriorly, lateral angles obtuse, apex in

 medially, and sinuate and darkened on either side of the notch; pygofers 

 sparsely spined, narrowed basally, broad and equalling ovipositor. Male, 

 last ventral segment nearly as long as preceding; valve triangular, sub- 

 acute at apex, margins concave medially; plates short, about twice the 

 length of the valve, apices acute, margins spiny; pygofers greatly exceed- 

 ing plates, but tergite inflated and pressed laterally and terminally 

 against the pygofers.

External genitalia: Female, last ventral segment half longer than pre- 

 ceding, strongly narrowed posteriorly, posterior margin concave on 

 either side of a notched median tooth ; pygofers sparsely bristled, broad, 

 equalling ovipositor. Male, last ventral segment three-fourths as long as
