510 Coleopterological Notices, IV. 



Basal joint of the club short, composing one-third of the mass or even less ; 

 elytra not continuous with the prothorax at the sides, the humeri more 

 or less exposed and oblique ; body and legs intense black throughout. 



Pronotum with a regular but sparsely squamose design, the scales sparsely 

 scattered over the elytra toward the sides, and also more or less distinctly 

 clustered in several small spots on the third and fifth intervals.

Pronotum without regular squamose design, the elytral vestiture consisting 

 entirely of minute inconspicuous setse which become slightly more robust, 

 but scarcely squamiform, toward the sides, and with a squamose spot at 

 the base of the third interval 5 disjliiicta

Pennsylvania — Boheman. There are but few statements con- 

 cerning this species, which can be made with any degree of cer- 

 tainty. It however undoubtedly belongs to the present genus, and 

 is probably also a member of the albilatus division, having the elytra 

 cylindrical and continuous in outline with the prothorax at the sides. 



The omission of exact measurements of length and width is a 

 serious defect in the great work of Schonherr. 



2 Plesiobaris Signatipes n. sp.— Subcylindrical, convex, polished, 

 piceous-black, the legs slightly paler, more rufous with the knees black, ves- 

 titure extremely minute and inconspicuous with the exception of a few large, 

 widely scattered, white scales toward the middle and sides of the pronotum, 

 a denser lineolate spot of the same at the base of the third elytral interval, 

 and, behind the middle, a short even row of widely spaced scales on the second, 

 third and fourth intervals, also a few widely distant scales on the fifth inter- 

 val ; on the under surface the meso- and metasternal side-pieces are densely 

 clothed throughout with large white scales and also the last three abdominal 

 segments laterally. Head and beak sparsely, feebly punctured, the latter 

 moderately robust, feebly flattened toward apex, strongly, evenly arcuate and 

 fully as long as the prothorax, the antennae moderate, the joints of the funicle 

 slightly convex at the sides, the second and third subequal and about as long 

 as wide, the club small, briefly ovoidal, the basal joint composing fully one- 

 half of the mass. Prothorax one-fifth wider than long, the apex feebly arcuate 

 and two-thirds as wide as the base, the latter transverse, the median lobe 

 broad and exceedingly feeble ; sides parallel and straight to apical fourth, 

 then rounded, thence straight and not at all constricted to the apex; disk 

 with a rather wide but ill-defined impunctate line, the punctures rather large, 

 one-half as wide as the scutellum but very feeble and sparse, separated by 

 more than their own widths, becoming minute and still more feeble toward 

 the apex, and also near the base except in the middle. Scutellum very small, 

 subogival. Elytra barely twice as long as the prothorax and exactly equal 

 to the latter in width, the sides straight and continuous, broadly but not
