AMERICAN COLEOPTERA. 159 



One specimen from Mississippi, kindly sent me by Mr. A. Salle, 

 under the MS. name given by Baron Chaudoir. It is a smaller and 

 more graceful species than the one with which I have compared it, and 

 easily recognized by the elytral markings. The tooth of the labrum 

 is hardly apparent.

 Dr. Horn has kindly prepared a wood cut from the drawing which 

 he made from the specimen of this species in the Oxford Museum. 



Bit was found with other North American species in barrels 

 of turpentine, supposed to be from North Carolina. The 

 markings as will be seen resemble those of cinctipennis, with 

 the addition of a basal spot and an elongate spot on the 

 suture, extending nearly to the middle. The prothorax is 

 finely rugose ; the dark parts of the elytra are distinctly 

 punctured, and the tips are finely serrate. These characters indicate 

 that it belongs in the group with blunda, macra, cuprascens, etc. 



C neva<lica. — Coppery bronze, head moderately large, eyes less prominent 

 than in C. speraia, front sparsely hairy, finely striate near the eyes. 

 Prothorax nearly cylindrical, finely rugose, transverse impressions 

 deep, sides hairy. Elytra deeply but not coarsely punctured, marked 

 as in the adjoining figure, proportioned as in C. sperata, sutural spine 

 distinct. Legs long and slender, claws large, hind trochanters red. 

 Labrum transverse, nearly straight in front, not distinctly toothed 

 at the middle; palpi pale, last joint only dark. Length 11 mm.; .43 

 inch. 



■J,. — Prothorax with the sides slightly rounded ; elytra obliquely and broadly 

 subsinuate near the tip. 



5. — Prothorax with the sides straight, and the base somewhat flattened; 

 elytra obliquely and strongly sinuate near the tip; anterior angle of the sinua- 

 tiou obtuse and rounded. 



Nevada, Mr. E. P. Austin. This species is allied to C. sperata^ but 

 difi"ers by the tooth of the labrum being obsolete; by the markings of 

 the elytra not connected at the side margin, and by the posterior part 

 of the humeral lunule less oblique, not hooked, and by the medial 

 band less prolonged behind. Finally the prothorax of the 9 is less 

 distinctly flattened near the base. 



<\ politula. — Above black, somewhat shining, slightly tinged with blue 

 and bronze on the head and prothorax; beneath and legs blue, abdomen fer- 

 ruginous. Head striate near the eyes, front convex very finely striate. Pro- 

 thorax finely rugose, not longer than wide, transverse impressions deep, sides 

 broadly rounded. Elytra convex, oblong, finely and densely punctulate, tips 

 rounded, obsoletely serrate, sutural spine very small, terminal lunule repre- 

 sented by a narrow short white line, which is sometimes obsolete. Labrum 

 white irregularly rounded in front, tooth obsolete; labia! palpi pale, with the 

 last joint dark. Length 12 mm.; .476 inch.
