at the same place on three different years, only on sunny clays, when 

 they flew to the face of the bank and often crawled into small open- 

 ings. They evidently pupate in burrows in such banks and in the 

 earth clinging to the roots of uprooted trees.

1844, p. 157. 



Elongate, rather slender. Black, sparsely and finely pubescent ; elytra, 

 except the very narrow sntural and side margins, dull yellow ; legs reddish- 

 brown. Antenna? half the length of body, second joint very small, obconic, 

 third as wide as and slightly longer than fourth. Thorax one-half longer 

 than wide; sides nearly straight, feebly curved on apical third; disk mod- 

 erately convex, rather densely and finely punctured; hind angles obtuse, 

 slightly excurved and divergent, not carinate. Elytra with sides nearly 

 parallel to apical third, thence converging to the acute tips ; striae feebly 

 impressed, punctate ; intervals subconvex, densely punctulate. Length 10.5- 

 11 mm. 



Starke and Posey counties; scarce. May 19-June 11. Beaten 

 from blossoms of cherry trees.

II, 1845, 216. 



Oblong, rather slender. Black, shining ; labrum and thorax red, the 

 latter with a broad median black stripe. Antennae strongly serrate, with 

 second joint small, obconic ; third as long and nearly as wide as fourth. 

 Thorax slightly longer than wide, sides feebly rounded ; disk sparsely and 

 rather coarsely punctate ; hind angles moderately divergent, with a distinct 

 oblique carina. Elytral striae with deep, coarse punctures ; intervals sub- 

 convex, sparsely and roughly punctulate. Length 7.5-9.5 mm. 



Orange and Crawford counties; May 26-June 12. Twenty or 

 more specimens were taken from stems of wheat in an upland field 

 near Wyandotte Cave, and a few beneath logs and stones along the 

 margin of the same field. 



C. copei Horn, length 12 mm., was described from Virginia and 

 has been taken near Cincinnati.

 Elongate, slender, subcylindrical. Dull sooty-brown or piceous, faintly 



bronzed, sparsely pubescent ; legs, epipleura and often the very narrow mar- 

 gins of thorax and elytra and suture of latter dusky reddish. Third joint 

 of antennae three times as long as second. Thorax one-half longer than 

 broad, male, one-fourth, female ; sides nearly straight, disk densely and 

 finely punctured, with a median basal impression ; hind angles rather strong- 

 ly diverging, indistinctly carinate. Elytral striae finely punctate ; intervals 

 flat, rather coarsely and densely punctulate. Length 11.5-16 mm. 



Porter, Marion, Lawrence and Vigo counties; frequent. March 

 22-May 6. Occurs on vegetation, usually close to the ground. The
