Elongate, slender. Brassy black or dark olivaceous, feebly shining; 

 each elytron with three pubescent spaces, the middle one elongate; often 

 also a small spot on side near the end of the middle one. Front flat, with 

 a depression at its upper part. Thorax very little wider than long, slightly 

 narrowed at base, sides feebly curved, hind angles with a well defined 

 straight carina ; disk with a median depression near apex, lateral depres- 

 sions feeble; surface transversely strigose-punctate- Elytra as in fallaz. 

 the basal impressions deeper. Length 6-8 mm. (Fig. 311. ~b.)

 elytra and notched front margin of presternum readily distinguish 

 this species from fallax.
