to the form of the humeri, the elytra being abruptly much wider 

 than the base of the prothorax, and in the type there is no trace of 

 a squamose maculation behind the middle of the elytra, nor any 

 indication of such a spot, as all the punctures are occupied by small 

 slender setae. 



PYCWOBARIS n. gen. 



In many respects this genus is allied to Ban's, but its species have 

 a distinctly different habitus due to the scaly vestiture. In its 

 structural characters, it is similar to Baris in the form of the anten- 

 nal club with its basal joint polished and composing fully one-half 

 of the mass, also in its short robust beak and free tarsal claws. The 

 flat prosternum separates the coxa? rather more widely than in any 

 species of Baris, and in this peculiarity it approaches Onychobaris ; 

 the fine and abrupt frontal groove differentiates it, however, from 

 both of these genera and allies it with Stictobaris, from which again 

 it differs in its robust convex body and non -tubulate prothorax. The 

 prothorax is more distinctly constricted near the apex than in Baris, 

 but is never tubulate. 



The beak is always shorter than the prothorax, the epistomal lobe 

 short, truncate and limited at each side by a small oblique fissure 

 as in Baris. Mandibles well developed, arcuate, overlapping in 

 repose and deeply notched at apex. The buccal opening is rather 

 smaller than in Baris, and its plane is more oblique to the under 

 surface of the beak behind it. The scutellum is quite different from 

 that of the last-named genus being distinctly bisinuate at apex. 

 Tarsal claws rather long, widely divergent. 



Our two species may be defined as follows: — 



Vestiture rather sparse, the whitish scales very narrow, producing merely a 



decided pruinose appearance 1 prilinosa 



Vestiture dense, the scales broad, almost entirely concealing the surface.

(Baris). 



Robust, oblong-oval and strongly convex, black throughout, the 

 integuments polished but clothed uniformly, although not very 

 densely, with long narrow subrecumbent scales. The beak is robust 

 and feebly arcuate, scarcely more than three-fourths as long as the 

 prothorax, the antennae rather short and robust, with the second
