AMERICAN COLEOPTERA. 235 



Hub. — Texas, various localities. One specimen is labeled New 

 York, possibly in error. 



5. C Minimis * n. sp. — Dark brown, a little more than half as wide as long, 

 evenly oblong, elliptical, scarcely gibbous in profile, pubescence moderate. Inter- 

 mixed coarser punctures of the head moderately numerous, rather fine and 

 evenly distributed, those of the pronotal sides distinctly coarser and denser; 

 those of the elytra for the most part less coarse than at the sides of the prono- 

 tum. visible over the entire surface, but sparser and a little finer toward the 

 base, with scarcely any tendency toward a serial arrangement at any part. 

 Metasternum sparsely evenly punctate, the punctures about equal in size to 

 those of the head. Hind coxal plates punctate. Eighth antenna] joint triangu- 

 lar, one-half longer than wide. Front tibise bisulcate, middle tibiae not sulcate. 

 Length 2.4-3.7 mm. 



Hab. — The typical form above described was taken at Oracle, 

 Ft. Grant, and Santa Rita Mountains, Arizona, by Mr. Schwarz. 

 A series from the Cape Region of Lower California (collections of 

 Fuchs and Beyer) is not appreciably different. Specimens from 

 Texas (San Diego, Brownsville, Hockley, Shovel Mt„ "S. W. Texas") 

 are more coarsely closely punctured, the punctures of the head but 

 little finer than those of the pronotal sides. They thus approach 

 sedans, but the color, longer and more conspicuous pubescence, and 

 lack of distinct serial arrangement of punctures of the elytra are 

 all as in the present species. 



6. C. estriatum Horn.— Dark brown, robust, fully three-fifths as wide as 

 long, broadly evenly oblong-elliptical, not at all gibbous in profile; pubescence 

 very fine and short. Coarser punctures almost entirely lacking on head and 

 pronotum, very fine but traceable on the elytra, where they tend to arrange 

 themselves laterally in longitudinal bands as in grande. Lateral stria? lacking. 

 Metasternum sparsely finely punctate at middle, smooth at sides. Antennas and 

 tibise as in grande. Length 4.5 mm. 



Hab. — Lower California (San Fernando). 



* Dorcntoma micans Boisd. — A Mexican example bearing this label, from Mr. 

 Gorham, is near mutans, but differs in the coarser punctures of the head being 

 nearly absent, and by the metasternum being nearly im punctate at sides. 



C. palmarum Chev. — A specimen of this species from San Domingo sent me by 

 M. Pic has the front tibise bisulcate, middle tibise without grooves, metasternum 

 punctured at sides, elytra without lateral stria. It is thus to be placed near 

 sedans and mutans. It is, however, much larger and more robust than either, 

 with the coarser punctures of the head and pronotum very inconspicuous, while 

 those of the elytra are distinctly arranged in irregular double lines.
