Farm : Robust, widening distally. Length, 4 to 4.5 mm. Vertex nearly 

 twice as long on middle as next the eye, twice as long as broad, obtusely 

 angled apically, margins straight. Pronotum half longer than vertex, 

 lateral margins short, posterior margin slightly emarginate, disc trans- 

 versely wrinkled. Elytra moderately long, equalling or slightly exceed- 

 ing abdomen, broad, nearly truncate posteriorly. 



Color: Black; vertex with broad line, a spot against either eye, several 

 apical and preapical spots, yellow. Pronotum with a few yellow spots. 

 Scutellum ^vith yellow spots along margin and at apex, two curved basal 

 lines on either side of the middle. Elytra with ner\-ures broadly yellow. 

 All the above yellow markings may be lacking, resulting in a shining 

 black form. On the other hand, the yellow markings may be much 

 stronger and the eljrtra may be smoky or fuscous with the nervures 

 broadly margined with fuscous. Face black with yellow arcs and some- 

 times with yellow spots. Front and middle legs yellow from tip of 

 femora on. 



External genitalia: Female, last ventral segment a little longer than 

 the preceding, lateral angles produced, subacute, between them the pos- 

 terior margin is widely emarginate, the middle portion slightly roundingly 

 produced; pygofers broad and short, exceeded by the ovipositor, sparsely 

 spined on distal half. Male, valve about half as long as last ventral seg- 

 ment, rounding posteriorly; plates about two and one-half times as long 

 as valve, tapering to subacute apices which exceed the pygofers. 



Distribution: Reported from Riley count>\ 

 Hosts: Taken from grasses.
