The above short characters will serve to distinguish the exilis 

 of Newman from the species which follows. The figure is from 

 the original specimen from which Mr. Newman drew up his de- 

 scription, and a good representation of it, with descriptions, will 

 serve to point out the peculiarities of its structure more forcibly 

 than words, and show how it differs from the foregoing genus, and 

 the one immediately following, all being nearly allied. 



Sp. 2. Macrones rufus. (PI. I. fig. 8.) 



Rufous brown, with a broad ring of black on the first joint of 

 the antennae, and another of the same colour on the hind femora. 



Head projecting considerably beyond the eyes into a short broad 

 snout, with the sides parallel, much contracted immediately behind 

 the eyes ; eyes small, subovate, black. Antennae geniculate, fili- 

 form, 11-jointed; 1st joint long, clavate, equalling in length the 

 three following; 2nd joint small rounded; 3rd to 11th subclavate, 

 gradually decreasing in length. Thorax broader than the head, 

 with a strongly marked raised ring in front ; behind which is an 

 expanded portion, having a spine on each side, and tuberculated 

 above. Scutellum small, subtrigonate. Elytra a little broader than 

 the thorax, gradually tapering to sharp points, terminating before 

 the apex of the abdomen and gaping at the suture, marked above 

 with four elevated longitudinal ridges, and the surface somewhat 

 rugose. Abdomen long, clavate, five-jointed. Legs long, with 

 the femora clavate.
