Santarem and Ega, Amazons. In form and colour this species 
resembles several other tropical American species, but it differs in the 
elytra being quite free from impressed striz, and in other points. The 
setiferous punctures are peculiar in not being placed in the situation of 
the 8rd interstice, or in the 8rd stria; one only is on the disc, towards 
the sides, the others are sub-marginal or sub-apical. The impressed 
sub-marginal stria near the apex is obsolete, existing only as a short 
impression distinct from the apex.
