 or greenish-yellow, apex with black spot, margins of reflexed portions, a 

 line from these to ocelli, and a pair of loops on the disc, black. Scutel- 

 lum with distinct black marks. Elytra grayish-green or reddish, unicolor-

External genitalia: Female, last ventral segment very long, raised 

 medially, lateral margins narrowed posteriorly, posterior margin triangu- 

 larly produced; pygofers long, bearing a few heavy hairs and equalled or 

 slightly exceeded by the ovipositor. Male, last ventral segment about 

 twice as broad as long, antei'ior and posterior margins parallel; plates 

 very long and slender, margins with fine hairs and also with a row of 

 stout hairs or bristles, slightly exceeding the spiny pygofers.
