longer than the sutural and J longer than the prothorax. Supplement- 

 ary anal segment of the male inflexed, but visible from above; pygidium 

 of female longitudinally impressed at sides. Thighs stout, tibia? mod- 

 erate, straight, the front ones widest. Length, 3.3-4. mm. ; width, 

 1.6-1.9 mm.

 Taken in decaying cactus by Mr. L. E. Ricksecker, to 

 whom the species is dedicated in recognition of many favors. 



C. iiitens n. sp. 



Oblong subovate, moderately convex, piceous brown, antennae, legs 

 and under surface paler. Above rather sparsely pubescent, strongly 

 shining, without or with but the faintest trace of alutaceous sculpture. 

 Head moderately punctate, more finely so in front. Prothorax fully 

 | wider than long, subparallel basally, sides arcuately narrowed in 

 front, the apex § as wide as the base, hind angles well defined and 

 subrectangular as viewed from above, not appreciably retracted ; 

 punctuation moderately coarse and close, the punctures separated at 

 middle by from one to two times their own diameters ; closer and a 

 little coarser laterally. Elytra scarcely wider than the prothorax, 

 slightly wider than the sutural length, sides parallel for f their length, 

 then a little narrowed to apex ; punctuation similar to that of the 

 prothorax. Beneath rather densely punctate, the presternum more 

 coarsely, the abdomen more finely so than above. Tibiae nearly 

 straight and gradually widened apically, scarcely different in the 

 sexes. Additional anal segment in the males inferior in position. 

 Length, 3 mm. ; width, 1.4 mm. 



Five examples are before me, all taken at or near Mobile, 

 Ala., by Mr. H. P. Loding. 



By Horn's table this species would fall near antiquus, 

 from which it differs in its uniform color, more convex form, 

 longer pubescence, unmodified hind tibiae of the male, and 

 in several other details. Nitens does not agree very closely 

 with any of the species described by Murray or in the " Bi- 

 ologia," though seemingly nearest to ferrugineus Murr., of 

 Mexico. This latter, however, is said to have the head and 

 thorax very lightly and sparingly punctate, posterior angles 

 obtuse and scutellum scarcely punctate, none of which char- 

 acters apply to nitens.

Dr. Sharp believes this to be distinct f rom pallipennis Say, 

 and observes that it has the sides of the elytra less distinctly
