 and very dense punctation, its first four free dorsal joints with a 

 short carina in middle-line; tarsi short, their fourth joint very feeb-

In appearance somewhat like buphthalmus , but the abdominal foremost

 the following darkly brownish. 



Head as broad as elytra, somewhat broader than pronotum, especially
