14 FREDERICK BLANCHARD. 



iitely impressed, the punctures not very closely placed, intervals a little convex 

 and punctulate. Body beneath shining, clothed with moderate, yellowish cine- 

 reous pubescence; prothorax with the submarginal lines distinct, impressed, 

 rather strongly descending, curved and reaching the middle, intercoxal process 

 long, marginal lines extending to tip, in front feebly joining the antecoxal lines, 

 which are not well marked, sides more closely punctulate than the prosternum, 

 no coarser punctures evident: sides of mesosternal fossa prominent, nearly ver- 

 tical ; metasternum, hind coxae and abdomen moderately punctulate, and with 

 scattered coarser punctures, last segment of abdomen at sides and tip more 

 coarsely and densely punctured ; hind coxal plates transverse behind, angles 

 rounded. Legs slender, the middle and hind tarsi as long as the tibise, the joints 

 gradually shorter, the last joint hardly equal to the second, which is much 

 shorter than the first, anterior tarsi shorter, the first joint hardly longer than 

 the last. Length .34 inch ; 8.8 mm. 



South Carolina, LeConte collection. One specimen in j)erfect 

 preservation, which appears to be a % . Precisely similar to some 

 forms of convexus, but -will be at once known by the dull lustre of 

 the prothorax caused by the very dense and fine punctuation. There 

 are also two South Carolina specimens in the Cambridge Museum 

 from the Dr. Samuel Lewis collection. In one of them the elytra 

 are paler. 



1.3. C aiigustatus n. sp. — Slender and elongate, shining black, clothed 

 above with a fine inconspicuous fuscous pubescence and short bristles curved 

 forward on the head and posterior part of the prothorax, and backward on the 

 anterior part and on the elytra, basal two joints of anteunai and legs yellow. 

 Antennge slender, slightly serrate, longer than the head and thorax, bases of 

 joints frequently more or less reddish. Head with frontal margin elevated, 

 broadly rounded, feebly convex, evenly and moderately punctulate; the thorax 

 is distinctly longer than wide in both sexes, feebly impressed behind the middle, 

 finely not closely punctulate on the disc, a little more strongly and closely at the 

 sides in front, no coarser punctures evident, sides broadly rounded, narrower in 

 front and slightly narrowed behind and sinuate, the angles feebly divergent, 

 strongly cavinate, the basal plicse are rather short, basal lobe tridentate. Elytra 

 a little wider than the thorax, widest behind the humeri, sides gradually rounded 

 and narrowed to the tip, strongly punctate striate, strife deeper at sides and apex, 

 intervals convex and punctulate. Body beneath clothed with fine cinereous pu- 

 bescence, closely punctulate, with coarser punctures along the middle of the 

 abdomen, last ventral more coarsely and densely punctate: prothorax with the 

 submarginal lines impressed, curved and reaching beyond the middle, prosternal 

 process long, marginal lines extending to the tip and in front of aud not dis- 

 tinctly joining the more or less obsolete antecoxal lines ; sides of mesosternal 

 fossa prominent, receding but little fnmi the perpendicular. Legs slender, the 

 middle and hind tarsi about equal to the tibise, the first joint longer, the second 

 equal to the last, finely spinous and pubescent beneath, the front tarsi are shorter 

 aud stouter and more spinous beneath, the first joint equal to the last. Length 

 .30 inch ; 7.7 mm.
