Form: Short, robust forms, not distinctly wedge-shaped as preceding

 as broad as long, humeral margins seemingly forming a part of the 

 posterior margin. Elytra short and broad, almost truncate apically, ex- 

 ceeded by abdomen, outer costal veins not strongly reflexed. 



Color: Brownish; vei'tex nearly reddish-brown with margins, tip, 

 median and basal transverse lines and a median longitudinal line, light.

 across base and a broader one across tip of clavus, the rest with the light 

 nervures heavily margined with brown. Face light bi-own with heavy 

 dark arcs. 



External genitulia : Female, last ventral segment moderately long,
