Coleopterological Notices, IV. 403 



dense and peculiar, consisting of long oblique uneven eroded channels, which 

 are evidently formed by the coalescence of reniform punctures of the tychioides 

 type, but also with an even median line, entirely impunctate and finely 

 granulato-reticulate. Elytra at base one-third wider than the prothorax, fully 

 two and one-half times as long, one-half longer than wide, ogival in apical 

 half, the sides thence straight and parallel to the base ; humeri right, promi- 

 nent but narrowly rounded ; striae deep, punctate toward the sides. Length 

 2.0 mm. ; width 0.85 mm. 



Rhode Island. 



This species, while allied to tychioides and sculplicollis, is dis- 

 tinct from both in the narrow granulose clearly limited impunctate 

 median line of the pronotum ; the latter is larger than in sculpti- 

 collis, but smaller than in tychioides. It is represented by a single 

 male example. 



29 S. SClllpticollis n. sp. — Narrowly oval, convex, feebly shining, 

 black, the antennae piceous, the legs red, darker near the coxae, the tarsi 

 piceous ; elytra bright rufous, the suture broadly, suffusedly blackish ; vesti- 

 ture sparse and uneven, fine and sparse at the sides of the prothorax, con- 

 fusedly mottled with condensed areas of larger yellowish-white scales and 

 small sparse slender squamules on the elytra ; under surface clothed sparsely 

 with small elongate squamules, very dense on the met-episterna. Head dull, 

 subglabrous ; constriction very deep ; beak in the male thick, dull, punctate, 

 sparsely squamulose, evenly cylindrical, not tapering, evenly, feebly arcuate, 

 distinctly longer than the head and prothorax, with the antennae inserted 

 just behind apical third, in the female slightly longer and smoother, evenly 

 cylindrical, evenly, moderately arcuate, nearly three-fifths as long as the 

 elytra, with the antennae inserted at apical two-fifths ; antennae moderate, the 

 second funicular joint much shorter than the next two. Prothorax small, 

 slightly wider than long, convex, strongly, evenly rounded at the sides, feebly 

 narrowed but scarcely at all constricted near the apex, very deeply, densely 

 sculptured, the sculpture consisting of moderately small reniform punctures, 

 close-set and often coalescent, with the narrow interspaces more or less punc- 

 tulate, without trace of median line. Elytra at base one-half wider than the 

 prothorax, fully two and one-half times as long, elongate-ogival, the sides 

 becoming parallel and nearly straight in basal half; striae distinct, obsoletely 

 punctate. Length 2.1-2.25 mm. ; width 0.9-1.0 mm. 



Virginia ; Indiana ; Texas. 



A common species, allied to tychioides, but abundantly distinct 

 in its much smaller, more coarsely and densely sculptured protho- 

 rax and very different beak, also in the shorter second funicular 

 joint, and sparser and narrow scales of the metasternum. 



30 S. iiistat>ilis n. sp. — Oblong-oval, stout, convex, intense black, 

 polished when denuded, the pronotum feebly alutaceous, with the punctures
