548 Coleopterological Notices, IV. 



Prothorax parallel at the sides in basal two-thirds, the beak shorter, strongly 

 arcuate ; second funicular joint quadrate ; elytra not more than twice as 

 long as the prothorax ; color intense black throughout, the antennae and 



tarsi rufous 1 ater 



Prothorax convergent at the sides from the basal angles ; beak longer and 

 less stout ; antennae more slender, the second funicular joiut distinctly 

 longer than wide. 

 Intense black throughout the body and antennae, the tarsi rufous ; protho- 

 rax short, the apex not much more than one-half as wide as the base; 

 elytra nearly two and one-half times as long as the prothorax. 



2 longipennis 



Pale rufo-testaceous throughout ; prothorax less transverse, the apex much 



more than one-half as wide as the base ; elytra about twice as long as the 



prothorax ; size somewhat smaller 3 sesostris 



1 Ampeloglypter ater Lee. — Proc. Am. Phil. Soc, XV, p. 800; 

 ampelopsis (Madarus), Walsh and Riley, i. litt. 



Oblong, moderately convex, highly polished and black through- 

 out, the antennae and tarsi rufous. Head minutely, sparsely punc- 

 tate, convex, separated from the beak by a distinct transverse 

 impression; beak rugulose, very robust, strongly, evenly arcuate, 

 slightly longer than the prothorax in the male; antennae stout, first 

 funicular joint robust, fully as long as the next three, second exactly 

 quadrate, three to seven much shorter and all strongly transverse, 

 increasing gradually in width, club robust, densely pubescent, the 

 basal joint constituting much less than one-half the mass. Protho- 

 rax two-fifths wider than long, the sides straight and subparallel in 

 basal two-thirds, then very abruptly and strongly rounded, almost 

 rectangular, thence subtransversely convergent for a considerable 

 distance to the apical tubulation, which is strong, constituting one- 

 fourth of the total length ; disk with a rather wide and subentire 

 impunctate line, the punctures very distinct, deep, sparse, with large 

 impunctate areas laterally, rugulose at the sides. The elytra are 

 about one-fourth longer than wide, twice as long as the prothorax 

 and a little wider than the latter at the somewhat prominent humeri ; 

 striae very fine but deep and abrupt ; intervals flat, very wide and 

 almost impunctate, the punctures of the single series being remote, 

 very feeble and scarcely visible. Abdomen extremely densely punc- 

 tate toward the sides. Length 2.8 mm. ; width 1.3 mm. 



Easily distinguishable by the rather broad form, with short par- 

 allel-sided prothorax and somewhat thicker beak. Eastern States.
