3. C 'bisectUS n. sp. — FiiHt joint of antennae twice as long as wide, 

 very slightly narrowed toward base, second scarcely more than three-lifths as 

 long as tlie third, and scarcely three-fourths as long as the fourth, fourth 

 distinctly shorter than the fifth, joints five to seven almost exactly ecjual, 

 fully one-third longer than wide ; lower surface and edges of middle femora 

 with setae nearly as in ilubius, except that the -upper discal line is very much 

 further from the axis, and very near the upper edge ; first joint of the poste- 

 rior tarsus much longer than the second, as long as the third and fourth 

 together, fifth slightly longer than the second and third together. Length 

 9.0 mm. 



Fairinount Park, Philadelpliia. 



Distinguished by the short and narrow elytra, the base of the pro- 

 notuni almost dividing tlie body into two equal portions. 



4. C. texailUS n. sp. — First joint of antennae twice as long as wide, 

 sub-cylindrical, very feebly narrowed toward base, second longer than in 

 liiseclus, nearly one-half longer than wide, two-thirds as long as the third, 

 three-fourths as long as the fourth, fourth as long as the fifth, which is nearly 

 one-half longer than wide. Antennae much darker than in the preceding 

 species. Middle femora nearly as in the preceding species ; tibiae and tarsi 

 black throughout; posterior tibiae much longer than the femora; first joint 

 of the tarsus much longer than the second, as long as the third and fourth 

 together, fifth about as long as the first two together. Length 10.8 mm. 



Texas. 



This species is abundantly distinguished from the otiiers by the 

 characters given. The head is relatively longer and narrower. The 

 iront is more strongly declivous than in any except Utoreus.

I>. pinguis n. sp. — Form robust, moderately convex ; sides parallel. 

 Color piceous- black, legs and under surface concolorous and slightly paler; 

 when immature piceous-brown throughout, legs paler ; integuments very 

 minutely reticulate, moderately shining. Head robust, wider than long; 

 surface moderately convex ; supra-orbital seta opposite the posterior limit of 

 the eye ; epistomal suture transverse and distinct, anterior edge broadly and 

 feebly emarginate ; labrum large, sides near the base very feebly divergent 

 anteriorly, then strongly convergent to the apical angles, which are rounded, 

 anterior edge strongly sinuate, disk i:)aler in color; emargination of mentum 

 more tlian twice as wide as deep, very broadly rounded at the bottom, sides 

 feebly arcuate, not toothed ; seco;jd joint of labial palpi much longer than 

 the third ; sub-mentum bearing upon the disk at each extremity a close pair 

 of setae ; antennae rather slender, fuscous, paler at base, second joint scarcely 

 one-half as long as the third, third distinctly loiiger than the fourth, joints 

 four to eight decreasing distinctly in length. Prothorax widest very slightly
