9 . Differs in having wider elytra, basal segment of 

 abdomen distinctly convex (instead of flat in middle), and 

 appendages somewhat shorter.

Belongs to a group of closely-allied species, distinguish- 

 able mostly by characters of the rostrum and elytra. The 

 intermediate carinae of the rostrum, which are partially con- 

 cealed by the clothing, slightly converge towards the base ; 

 in fulvus they diverge towards the base; there are also slight 

 differences in the base of elytra, in the clothing, etc. From 

 nanus it differs in the base of prothorax and elytra, in the 

 much sparser elytral setae, etc. Pictns has the inter-anten- 

 nary space decidedly narrower, scape shorter and more curved, 

 and elytral setae different. Nitidilahris is a somewhat wider 

 species, with median carina of rostrum apparently absent and 

 with dense elytral setae ; on the present species the setae are 

 never more than in three rows on an interstice, and in places 

 are in but one or two, they are also more depressed and 

 inconspicuous. Some of the scales on the under-surface and 

 legs have a golden or rosy gloss, especially in the males. 

 Seen directly from the side the rostrum appears to be 

 depressed at its junction with the head, although without a 

 conspicuously impresed line as on some species of the genus. 



POLYPHRADES HALMATURINUS, 11. sp. 



<$ . Black, appendages more or less red. Closely 

 covered with obscurely mottled brown and ashen scales, 

 becoming more or less metallic on under-surface; rather 

 sparsely setose. 



Eyes fairly large and ovate. Rostrum moderately long, 

 tricarinate, the sublateral ones slightly converging hiudwards 

 but not extending to base, median one narrow and distinct, 

 joined to a conspicuous apical triangle. Antennae compara- 

 tively thin; first joint of funicle as long as second and third 

 combined, second as long as third and fourth combined, 

 fourth to seventh transverse. Prothorax moderately trans- 

 verse, sides strongly and evenly rounded ; densely granulate 

 and punctate. Elytra briefly subovate, sides strongly rounded 

 and widest across basal third ; with regular rows of large, 

 subquadrate punctures, appearing small and in narrow striae 

 through clothing. Legs moderately long; claws short, equal, 

 and separated near the tip only. Length, 3J-3J mm. 



9 . Differs in having the prothorax slightly longer, 

 -elytra distinctly wider, two basal segments of abdomen rather 

 strongly convex (instead of the first flat in middle and the 

 second gently convex), and the appendages shorter.
