In the type the coarser punctures are conspicuous though not 

 very large. In the Florida examples these punctures become very 

 coarse and numerous, while in some of the Cincinnati ones they 

 may almost be called indistinct. There is present, however, every 

 degree between the extremes and I cannot discover any structural 

 peculiarities which will serve for specific separation. Passing over 

 this extraordinary variability of punctuation, the cylindrical form, 

 carinate metasternum and tibial grooves form a combination of 

 characters not duplicated elsewhere, and render the identification of 

 this species at once easy and certain. 



19. C. densiim n. sp. — Dark brown, head and thorax dull rufous; moder- 

 ately robust, slightly more than one-half as wide as long, oblong-oval, rather 

 narrowly rounded at extremities, scarcely visibly gibbous in profile ; pubescence 

 very short and fine, but moderately plentiful. Punctulation fine and dense, sur- 

 face minutely alutaceous and dull ; coarser punctures invisible, except in the 

 apical third or fourth of the elytra. Metasternum alutaceous, punctured 

 sparsely throughout. Eighth antenual joint broadly triangular, scarcely as 

 wide as long. Front tibise bisulcate, middle tibise finely but distinctly sulcate 

 close to the posterior margin. Length 2.5 mm. 



Hab. — Described from a single specimen taken at Washington, 

 D. C. (Hubbard & Schwarz collection). Possibly a variety of 

 boreale, but the latter certainly has non sulcate middle tibise and 

 LeConte says that there are no scattered punctures on the elytra. 



20. C. (lichrouni n. sp. — Piceous brown, head, thorax and ventral surface 

 rufous; form oblong-elliptical, twice as long as wide, not at all gibbous in pro- 

 file; upper surface finely, evenly, rather closely punctulate throughout, coarser 

 punctures virtually absent. Metasternum with dual punctuation, the coarser 

 punctures reaching the sides. Eighth antenna! joint broadly subquadrate-trian- 

 gular, nearly as wide as long. Front tibise bisulcate, middle tibise finely sulcate 

 close to the posterior margin. Length 1.8-2.5 mm. 



Hab. — Michigan (Detroit) ; Virginia (Pennington Gap) ; West 

 Virginia (Berkeley) ; Louisiana (New Iberia, Soltau). 



21. C. nigripeune n. sp.— Head, thorax and lower surface rufous, elytra 

 black ; form elongate-oval, slightly more than half as wide as long, not gibbous 

 in profile. Pubescence fine and sparse. Surface very finely alutaceous, the 

 lustre somewhat dull ; coarser punctures fine and not very obvious on the head, 

 pronotum very finely punctulate on the disk, a little more coarsely so at the
