Form : Small and robust. Length, 3 mm. Vertex a little longer than 

 wide, rather acutely pointed, at least more acute than in two following 

 species. Pronotum long, not over twice as broad as long, strongly con- 

 vex anteriorly, lateral margins very short, humeral margins long, broadly 

 rounding with slightly concave posterior margin. Elytra slightly longer 

 than the abdomen, somewhat flaring, the clavus well reticulated, the 

 central anteapical cell divided. 



Color: Brown; vertex with two triangular fuscous, apical spots, a 

 black spot above each ocellus, a medially widened, transverse, broad band 

 on the disc, with a pair of light fuscous basal spots and a dark median 

 longitudinal line. Pronotum with five white longitudinal lines, two large 

 fuscous apical spots and irregular fuscous spots posteriorly, parallel to 

 anterior margin. Scutellum with dark basal angles. Elytra with nervures 

 broadly white and uniformly bordered with fuscous, sometimes the cells 

 entirely fuscous. Face black with white arcs. 



External genitalia: Female, last ventral segment one-third longer 

 than preceding, posterior margin broadly and roundly slightly concave;
