Coleopterological Notices, IV. 599 



New York; Indiana; Kentucky; Dakota; Colorado; Texas. 



The description is drawn from the male ; in the female the beak 

 is quite distinctly longer and rather more slender, evenly, some- 

 what strongly arcuate throughout, cylindrical, smooth, shining and 

 minutely, sparsely punctate except at base, the antennae inserted 

 distinctly beyond the middle, and with the club unmodified. 



This species is the most protean in its variations of any baride 

 which I have seen ; more especially in the vestiture of the upper 

 surface, which may consist of very slender sparse squamules, or 

 robust oval dense and very conspicuous scales, with every inter- 

 grade between these limits. The series before me consists of nearly 

 sixty specimens. 



28 CentriiiUS pingliescens n - sp. — Oblong-oval, stout, moderately 

 convex, dull black, tbe antennae and tbe tibia? at least toward apex, rufescent ; 

 vestiture on the upper surface consisting of yellowish scales, elongate-oval 

 and dense on the elytral intervals, minute, slender and inconspicuous on the 

 pronotum, but larger and denser at base near the sides and toward the middle 

 and also in the subapical constriction, large, yellowish-white and very dense 

 beneath Head somewhat finely, deeply, rather densely and conspicuously 

 punctured, the impression broad and very feeble, with an elongate median 

 fovea; beak in the male rather stout, deeply, coarsely and rugosely punctate, 

 nearly evenly, distinctly arcuate and somewhat abruptly very strongly so 

 near the base, a little longer than the head and prothorax ; antenna? inserted 

 well beyond the middle, the basal joint of the funicle rather short, stout, the 

 second fully three-fourths as long as the first and equal to the next two 

 together, sixth and seventh internally prominent, club very robust and 

 abrupt, as long as the five preceding joints combined, extremely densely 

 clothed with short recumbent setiform squamules, the basal joint constituting 

 one-third of the mass, with a glabrous internal area, not extending much 

 beyond the middle, at the centre of which there is a very minute but acute 

 and prominent spicule. Prothorax two-thirds wider than long, the sides 

 broadly, evenly rounded in apical half, becoming parallel and straight thence 

 to the base, the subapical constriction feeble but distinct ; apex distinctly less 

 than one-half as wide as the base ; disk very finely, extremely densely punc- 

 tured and dull, with barely a trace of a very narrow partial impunctate line. 

 Scutellum very densely and conspicuously squamose. Elytra slightly wider and 

 two-thirds longer than the prothorax, but slightly longer than wide, the sides 

 strongly convergent ; apex rather abruptly, obtusely but not very broadly 

 rounded; stria? rather coarse, deep, with the seta? minute; intervals flat, 

 more than twice as wide as the grooves, coarsely, deeply, very densely and 

 rugosely punctured throughout. Abdomen with the scales slightly smaller and 

 sparser in the middle toward base in the male. Prosternum with a transverse 

 subapical excavation, the coxa? separated by nearly one-half of their own 

 width Length 4.1 mm. ; width 2.0 mm.
