black, the elytra except for dark spots, the tibiae and more than the 

 basal half of the antennae distinctly red. Squamosity of head and prono- 

 tum golden, the latter with large and dense lateral patches of whiter 

 color. Elytra partly abraded, apparently with golden clothing, but with 

 a broadish white stripe extending back from each shoulder to the apex, 

 and with the white erect setae very slender, long and conspicuous on the 

 posterior part. The setae of tlie hind tibiae are also slender and 

 elongate, but not so long as the longest of those on the elytra. Rostrum 

 shining, with the punctate lines very fine, the head simple without trans- 

 verse constriction behind the eyes. Antennae rather long, slender, funicle 

 joints all more or less elongate, not at all moniliform. Pronotum 

 strongly rounded at the sides, much narrowed in front and deeply im- 

 pressed there, the posterior impressions wanting or at least very feeble. 

 No erect fine setae on the pronotum such as are seen in P. Icpfofhrix. 

 Elytra almost simply convex, \ery slightly emarginate at the base, but 

 with distinct humeral angles, which are practically rectangles, the sides 

 are slightly rounded so as to be a little wider about the middle than 

 at the base, but even at tlie widest part they hardly exceed the pro- 

 notum (at its middle) in width. Length, female, I'ix 3 mm.

Proterhinus ater n. sp. * 



A black or almost lilack species, with long dark, almost unicolorous 

 antennae, the scape large and unusually long in the male, almost like that 

 of the female. Clothing golden, the elytra largely bare and black, the 

 .squamosity forming maculations. Belongs to the species with simple 

 humeral angles and is allied to the variable P. siiiiilis. 



Eyes not at all large, rostrum of female polished and with the 

 grooves distinct. Scape thick and long, rather stouter in tlie male, but 

 pbout equal in length to that of the female; second joint longer than 

 wide and stouter tli:in the following ones, wliich are all elongate, the 

 antennae after the two l)asal joints, have an unusually slender appear- 

 ance. Tlie lengtlT of one of them in the male is just about equal to that 

 of the elytra. Tlie anterior impression of the pronotum is always present, 

 but the posterior pair are very faint or not noticeable at all in dorsal 

 aspect. The squamosity forms a dense patch on each side of the 

 pronotum. Lobate joint of the front tarsi distinctly small. Elytra of 

 quite simple form, often noticeably flattened or subdepressed on the dor- 

 sum, tlie pale erect setae very conspicuous on the posterior part and in 

 quite un.'ibradefl examples witli a regular row of almost similar ones
