Coleopterological Notices, IV. 511 



abruptly romided behinrl ; humeral tuberosities very small and feeble, not at 

 all evident laterally; disk with very fine, moderately deep strife, the inter- 

 vals flat, four or five times as wide as the strife, the second and third sensibly 

 wider, each with a series of minute, feeble, distant and indistinct punctures. 

 Abdomen very minutely, obsoletely and sparsely punctured toward the middle. 

 Prosternum flat, not sensibly impressed, separating the somewhat small coxfe 

 by about two-thirds of their own width. Length 1.75 mm. ; width 0.6 mm.

The antennal differences between this species and diyancla are 

 very radical in the structure of the club, but I can perceive no other 

 divergencies of a g'eneric nature, and parallel inconstancy of this kind 

 is well known in Onychobaris. Signatipes approaches more closely 

 to the published characters of T-aignum, than other species which 

 I have seen, but differs in its piceous color, apparently sparser pro- 

 notal punctures and in several other characters, among the more 

 importnnt of which is the form of the basal line of the prothorax, 

 said to be rather profoundly bisinuate in T-aignum.

 (Pseudobaris). 



Oblong-cylindrical, convex, polished, rufo-testaceous in color, the 

 beak, under surface, knees and elytral suture piceous-black ; punc- 

 tures of the upper surface bearing very minute and inconspicuous 

 setae, with a few large scattered whitish scales toward the middle 

 and sides of the pronotum, and a denser spot of the same at the 

 base of the third elytral interval, the remainder of the elytra with a 

 few large widely dispersed scales arranged subtransversely, and of 

 which a loose spot on the second and third intervals is more distinct ; 

 meso- and metasternal side-pieces and lateral portions of the last 

 three ventral segments abruptly very densely squamose. The beak 

 is robust, strongly arcuate and fully as long as the prothorax, the 

 antennie slender, the funicle long, with joints two to four a little 

 lonuer than wide and decreasing very slightly in length, the club 

 small, with the basal joint composing distinctly more than one- 

 half of the mass. Prothorax one-third wider than long, the sides 

 parallel and nearly straight to apical fourth, then convergent and 

 constricted, the base broadly and very feebly bisinuate, the disk 

 with a wide but uneven impunctate line, the punctures rather 

 coarse, deep and somewhat dense. The elytra are as in signatipes, 

 but with the intervals equal and about four times as wide as the 

 grooves. The prosternum is broadly, scarcely perceptibly impressed
