A narrower and more slender insect than the precedinsf, and 

 differently coloured, with longer and more slender antennae, the 

 pubescence on the elytra showing a decided tendency to run in 

 rows ; the prothorax is narrower, being not more than half again 

 as wide as long. I have not seen a male of this species.

The front part of the disc of the prothorax is much less closely 

 punctulate than the other parts of the same, — a very distinctive 

 character. This species is very distinct from all previously described 

 on account of its . less crowded puncturation and (especially) 

 the structure of its antennae, which are stouter than in any 

 of the preceding and have each of the five joints preceding the last 

 slightly compressed and very gently dilated from the base to the 

 apex so that the apical portion of the antennae appears to be 

 slightly serrate. This antennal character might possibly justify 

 generic separation, — but as still more decided antennal modifi- 

 cations appear in the species next to be described I think its 

 value of less importance than it appears at the first glance. The 

 insect possesses all the essential characters of Tomyi'is, — proster- 

 num evenly concave in front, claws appendiculate with the basal
