AMERICAN COLEOPTERA. 117 



D. carolinensis n. sp. — Brownish testaceous. Head triangular, each side 

 impressed, lateral angles somewhat elevated, surface subopaque, granulate. Thorax 

 transversely hexagonal, apex wider than base, lateral angles prominent but obtuse, 

 disc convex with an obtuse, sinuous, costiform elevation extending from apex to 

 base on each side of middle, surface granulate. Elytra broadly oval, a little more 

 narrowed at apex, convex, each with the suture slightly elevated and three well 

 defined sharp costse, the margin also costiform, intervals concave, irregularly 

 biseriately punctulate. Body beneath and legs somewhat paler than above. 

 Length .07 inch; 1.75 mm. (PL IV, fig. 11). 



Resembles the European I), sulcatus Brongn., but less robust, the 

 thorax less transverse, and the humeri of the elytra more rounded. 



Occurs near Morganton, North Carolina, ( Morrison). 



D. angulicollis n. sp. — Brownish testaceous. Head triangular, above granu- 

 late in lines, a smooth space over the insertion of the antennae. Thorax very 

 transversely hexagonal, the lateral angles acute and prominent, apex slightly 

 prolonged at middle and on each side within the front angles emarginate, the 

 latter prominent anteriorly, disc convex, on each side a slender carina diverging 

 posteriorly bifurcating in front forming a Y, near the lateral margin anteriorly 

 a short carina, surface variably granulate. Elytra broadly oval, humeri rounded, 

 convex, suture slightly elevated, disc of each side tricostate the intervals densely 

 and irregularly triseriately granulate-punctate, the marginal interval smoother at 

 base. Body beneath somewhat paler than above, comparatively smooth. Length 

 .07 inch; 1.75 mm. (PI. IV, fig. 12). 



Resembles more closely D. sulcatus and has the lateral angles of the 

 thorax even more acute. It differs also from sulcatus and carolinensis 

 in the form of the apex of the thorax. D. sulcatus differs from both 

 our species in having the intervals of the elytra ornamented with 

 a double series of very regularly placed coarse punctures, and by the 

 humeri of the elytra quite distinctly angulate and not rounded. 

 Occurs in California and given me by Mr. Ulke. 



PEPLOGLYPTUS Lee. 



This genus was established by Dr. LeConte for a curious little Histeride 

 allied to Glgmma, (see Trans. Am. Ent. Soc. 1880, p. 189), differing 

 especially in the position of the antennal fossae. On plate VI, fig. 1, will 

 be found a much enlarged representation of the upper surface ; figure 2 

 gives a view of the head and thorax seen from the front. On the right 

 side of the latter the antenna is extended so that the fossa under the 

 anterior angle is seen. The scape when at rest is received in a groove 

 at the side of the head extending to the labrum, the funiculus and club 

 are folded backward as shown in the left side of figure 2. 



PSEPHENUS Lee. 



In order that some points in the structure of this rather anomalous 

 genus may be better understood I have prepared an outline sketch on 

 plate VI, fig. 14, of the upper surface of a male. The sexual differences
