NORTH AMERICAN COLEOPTERA. 



261 



This species differs particularly from all those with punctate head 

 by the punctures of the clypeo-frontal region being very coarse and 

 deep, but well spaced. The only species with which it might be 

 confounded is dentlculafa, which is, however, a broader species. 



Occurs in Colorado, Texas, Dakota, Georgia and California (Ulke). 



9. C. i>iiigui« Leo. — Oval, slightly oblong, uearly twice as long as wide, 

 surface feebly shining, distinctly alutaceous and bronzed. Antennje rufotesta- 

 ceous at base, the outer joints piceous. Head subopaque, sparsely finely punc- 

 tate, clypeo-frontal space more coarsely punctured. Thorax nearly twice as 

 wide at base as long, sides rearularly arcuately narrowed to the front, basal mar- 

 ginal line very feeble, surfa<-e distinctly alutaceous, punctures fine not close. 

 Elytra not wider at base than the thorax, the margin very nearly continuous 

 with that of the thorax, ural)one not distinct, disc finely striato-punctate, the 

 punctures small, moderately close not deeply impressed, the intervals much 

 broader than the strise, flat on the disc, slightly convex at the sides, without dis- 

 tinct interstitial punctures, surface very distinctly alutaceous, inflexed margin 

 with a row of clo.sely placed punctures along the inner border. Body beneath 

 piceous. shining, feebly bronzed. Prosternum closely punctate, side pieces 

 smooth. Al)domen sparsely, indistinctly punctate, the last segment more coarsely 

 and closely at the sides. Anterior and middle femora brown, posterior piceous, 

 bronzed, tibia? and tarsi rufotestaceous. Length .08- .09 inch. ; 2-2..5 mm. 



This species is very like a small dentkulaia, but differs in having 

 the entire punctuation of the surface finer and less deep, more espe- 

 cially in the elytral stride. The feebly punctate head makes this 

 species a natural intermediate l)etween those with the head decidedly 

 punctate or smooth. 



Occurs in Florida, North Carolina and Texas. 



10. C. seinula n. sp.-Oval, rather robust, surface shining, slightly brassy. 

 Antennje rufotestaceous at base, piceous externally. Head alutaceous, sparsely, 

 finely punctate, clypeo-frontal region very distinctly, not densely punctate. 

 Thorax one-half wider than long, widest a little in front of base, sides arcuately 

 narrowing to the front, basal marginal line very indistinct at the sides, surface 

 indistinctly alutaceous, the punctures rather fine, closely placed, but not dense. 

 Elytra a little wider at base than the thorax, humeri broadly rounded, urabone 

 not evident, strife slightly impressed, the punctures moderately course, close and 

 deep, the intervals very little wider, very slightly convex on the disc, more so 

 at the sides, the interstrial punctures indistinct and very fine. Body beneath 

 piceous black, slightly broi.zed. Prosternum coarsely punctured, the side pieces 

 smooth. Abdomen coarsely, but sparsely punctate. Femora piceous, tibia and 

 tarsi rufotestaceous. Length .09 inch. ; 2.25 mm. 



This species presents nothing remarkable. The head is finely and 

 indistinctly punctate as in pingvls, but the elytral stride are compara- 

 tively coarsely punctured The regularity of the oval outline is
