 vertex and notum pale, bordered with fuscous. Length 4^^ - 5 mm. 



Vertex distinctly transverse, a little longer than in irrorata but shorter 

 than in fusca; carinae distinct; front convex as in fusca. Pronotum short 

 and deeply emarginate as in the allied species. Elytral neuration similar 

 to that of fusca, the outer sector forked distinctly in advance of the inner. 



Color pale testaceous, the elytra fuscous with pale nervures, the are- 

 oles marked by a row of short white transverse veinlets along the lon- 

 gitudinal nurvures excepting the costal, becoming fewer on the membrane ; 

 the costal areole paler with three or four transverse fuscous clouds ; 

 carinse of the vertex, pro- and mesonotum pale, bordered with fuscous 

 lines ; sides of the pronotum with about three fuscous areoles behind the 

 eyes. Front pallid, tinged with yellow on its base, marked with a piceous 

 band at apex and a row of about six fuscous points next each lateral 

 carina. Clypeus tinged with yellow and faintly embrowned at apex. Pec- 

 tus and legs testaceous, faintly clouded with fuscous. Abdomen fuscous,
