arities of indubitable generic import. The principal of these are 

 the shorter beak, which is gradually stout and conical near the base 

 and not abruptly inflated, the channel beneath being broad, shallow, 

 and serving as a partial shelter for the antennal scape, the absence 

 of any trace of the transverse basal constriction, and the shorter 

 second joint of the antennal funicle. The mandibles are entirely 

 similar, but the trophi, and especially the maxillary palpi, seem to 

 be larger and better developed, and the tarsi are shorter, particu- 

 larly the second joint, which is but slightly longer and scarcely at 

 all narrower than the third, the fourth being nearly as long as the 

 first three together. 



1 Plocamus hispidulus Lee— Proc. Am. Phil. Soc, XV, p. 320. 



Oblong-oval, moderately convex, black, the beak rufous ; antennae 

 brown ; integuments densely clothed with large contiguous squami- 

 form plates, variegated with white, brown, and piceous, a transverse 

 spot of the latter color just behind the middle of the elytra especi- 

 ally noticeable ; under surface white; erect dorsal bristles very short 

 and sparse. Beak but slightly longer than the head and prothorax, 

 slender, arcuate, glabrous, linearly punctated and finely bicarinate 

 beneath from the antennae to the apex, but rapidly and conically 

 robust thence to the base, the basal portion densely clothed with 

 large rough concave and squamiform plates ; antennae inserted at 

 basal fourth on the under surface, the scape short, attaining the 

 head, the basal joint of the funicle slightly longer than the next two, 

 second one-half longer than the third, seventh obconical, nearly as 

 long as the fifth and sixth, club small, slender, not abrupt, oval, 

 compressed, sparsely pubescent on the inner, densely on the outer 

 side, devoid of sutures but with a small terminal button. Pro- 

 thorax small, transverse, constricted and tubulate at apex, rather 

 distinctly and densely punctate. Scutellum distinct, white, oval. 

 Elytra abruptly much wider than the prothorax, more than twice 

 as long as the latter, the sides subparallel toward base, gradually, 

 broadly and obtusely rounded behind, with a minute and feeble 

 sutural notch ; striae evident only as very fine partings of the crust. 

 Prosternum large, not in the least impressed, separating the coxae 

 by not quite twice their own width and evenly, transversely con- 

 stricted behind the apex. Length 1.9-2.2 mm. ; width 0.8-1.0 mm. 



Maryland. This species has been taken also by Mr. Ulke in the 

 District of Columbia.
