AMERICAN COLEOPTERA. 321 



greater convexity, relatively shorter thorax, color of legs, less shining 

 Mirface and the pruinose appearance produced by the short grey 

 hairs. 



Two specimens are before me, one from Nebraska, in the cabinet of 

 Mr. Ulke, another from California, received from Mr. Behrens, with a 

 catali\gue number 808. 



C. Breweri, n. sp. — Black, surface darkly bronzed, feebly shining. Head 

 closely and very coarsely punctured. Antennae with third joint distinctly 

 longer than the fourth. Thorax nearly square, very slightly longer than broad 

 median line slightly impressed at base, not very convex, surface densely and 

 coarsely punctured, punctures denser at the sides in front ; sides feebly rounded » 

 near the hind angles distinctly sinuate, angles slightly divergent, prolonged 

 backwards, sub-acute at tip and strongly carinate. Elytra as broad as thorax 

 subparallel in front, surface moderately convex, striate, strice finely punctured 

 intervals feebly convex, irregularly biseriately punctulate and transversely 

 wrinkled. Body beneath black, shining, sides of prothorax densely and coarsely 

 punctured, prosternum very sparsely punctured, pectus and abdomen sparsely 

 punctulate more densely at the sides. Legs piceous. Length .42 inch; 10.5 

 mm. 



This species belongs to Group VI, Candeze, and is allied to our 

 .'<plcn(Inis and conjungens, differing from the former in its more slender 

 form, less polished surftice, and from the latter by its distinctly bronzed 

 surface, more densely punctured thorax and feebly impressed median 

 line. The legs of conjungens, are also rufous. The bronze tinge of 

 the surface is very dark and equal on the thorax and elytra. 



A few specimens were captured in the high southeastern Sierra's 

 east of Visalia, California, by Prof. ]Jrewcr, to whom the species is 

 dedicated. 



C. praeses, n. sp. — Brownish, feebly shining without metallic lustre, sub-de- 

 pressed, beneath brownish testaceous, legs and epipleuraj much paler. Head 

 coarsely punctured, sparsely clothed with yellow hairs. Thorax longer than 

 broad, sides feebly rounded and slightly sinuate behind, angles acute prolonged 

 liackward, and strongly carinate ; disc with median line feebly iunpressed in 

 its entire length; surface coarsely and rather densely punctured, shining. 

 Elytra as broad as thorax sides feebly rounded, surface feebly convex, striate 

 striae not punctured, intervals slightly convex biseriately sparsely punctulate. 

 Body beneath densely punctulate except along the median line. Antennae and 

 parts of mouth (except tips of mandibles) pale yellowish testaceous. Length 

 .40 inch ; 10 mm. 



Closely allied to Bre.iceri and conjungens^ from both of which it 

 differs in its color, and also from the latter by its longer thorax. 

 In neither of the above cited species are the epipleurae paler than 

 than the upper surface of the elytra. The striae appear not to be 

 punctured, the punctures of the interspaces are so near the Btrias
