Longicorn Coleopter a of Tropical America. 123 



form elytra, not reaching the apex of the first abdominal seg- 

 ment and punctured throughout, the punctures being only a 

 little wider apart on the disk, with the interstices shining. 

 The muzzle is elongated, but rather broad. The legs long 

 and slender, with the thighs rather abruptly clavate and the 

 hind tibiaj not tufted. The antennie are elongate-clavate ; 

 Thomson describes the joints (from the sixth) as " paulo ser- 

 ratis," which is nearer the fact than Lacordaire's statement, 

 " non dent^es en scie." In the male the eyes do not reach the 

 median line of the front.

The antennge and legs are sometimes more or less black.

Having had an opportunity of examining a considerable 

 series of species of these insects, so curiously modified to attain 

 a close resemblance to different species of hairy bees, I think 

 Epimelitta may be very well incorporated with Charts, the only 

 differences being the broader thorax and more hirsute body. 



I. Elytra very short, cuneiform. Thorax broad, tumid on each side 

 near the hind angle.

 The elytra in this species are strongly emarginate along 

 their sutural margin, and the lateral edge is very little incurved.
