Antennae short, hardly extending beyond the base of the pro- 

 thorax, the three basal segments lying in a very deep channel 

 between the posterior margin of the eye and the outer margin of 

 the clypeus, the six apical segments thickened ; first segment 

 long and club-shaped, second somewhat shorter but thicker than 

 the third, which is slender, fourth shorter than third, fifth and 

 sixth more or less nearly equal. Protliorace much broader than 

 long, sides obliquely and gently curved, posterior margin sinuate, 

 with a median lobe ; surface convex, finely and moderately closely 

 punctate. Scutellum small, triangular. Elytra strongly convex, 

 at the base very slightly broader than the prothorax, sides rounded,
