8ubc\ lindric, with the scape chivate, reaching alino.st to 

 the middle of the prothorax, with the third joint longer 

 than the scape, the fonrth rather shorter than the scape, 

 the fifth and sncceoding joints gradnally decreasing in 

 length. Prothorax with a distinct conical tubercle at the 

 middle of each side, feebly tuberclcd on the disk. Elytra 

 rather short, regularly convex, gradually narrowed and sub- 

 truncate behind: the shouUlers slightly projecting. Femora 

 clavate-fusiform. Intermediate tibite entire. Claws of tarsi 

 divergent. Anterior cotyloid cavities strongly angulate 

 externally. Prosternal process simply arched. Intermediate 

 cotyloid cavities open on the outside. 



The female ditiers from the male by its slightly shorter 

 antenna:, its somewhat shorter elytra, and by having the last 

 abdominal ventral segment longer and sinuately emarginate 

 at the apex. (In the male this segment is rounded and not 

 emarginate.) 



In the ditficulty of finding a more satisfactory position for 

 this genus, 1 am content to place it near Phijmasterna. From 

 Phymasterna and all the genera of the same group it differs 

 by the complete absence of any notch or groove from the 

 intermediate tibi^, by the more elongate and coarsely granu- 

 lated eyes, and by the club-like form of the scape of the 

 antennas. The general form of the single species of the 

 genus is suggestive also of certain genera of the Crovssotides ; 

 but, owing to the structure of the claws, it can scarcely be 

 admitted into that group.

Nigro-vclutinus, tarsis et annulis antcnnarum albo-flavesceatibus

"With a deep uniform velvety black pubescence. Head 

 sparsely and not very distinctly punctured ; with a very fine 

 median impressed line running from the base to the occiput. 

 Antennje with the eighth and eleventh joints wholly, and the 

 basal halves of the third, fourth, and sixth yellowish testa- 

 ceous and clothed witii a whitish pubescence ; the rest of 

 the antennte velvety black. Prothorax with three feeblo 

 tubercles above — two anterior, one median posterior. Elytra 

 each a little prominent at the middle of the base, as well as 

 at the shoulder, sparsely punctured on the basal half, sub- 

 truncate at the apex. Tarsi (the claws excepted) teataceous
