One specimen, North Red River ; Robert Kennicott. Resem- 

 bles closely the Californian C. obscurus Lee., but the elytra are 

 less densely punctulate, and the thorax is a little more convex.

 pubescens, capite fortiter punctate, fronte concava, tliorace latitudine

 carinatis, elytris subtiliter striatis, interstitiis punctatis, pedibus runs, 

 antennarum articulo 3io sequente paulo longiore. Long. '70. 



New York and Canada; Mr. Kestlin. The thorax is a little 

 widened from the base to beyond the middle in the female, the 

 only sex known to me.

 capite fortiter, thorace modice medio parcis punctate, hoc latitudine 

 liaud breviore antrorsum angustato, angulis posticis elongatis valde 

 divergentibus, elytris thorace paulo latioribus striis fortiter punctatis

One male, Sacramento Valley, California ; Mr. Rathvon. 

 Smaller than En. lautus, more shining, and much less punctured. 



ANACHILUS LEC. 



317. A. mandibtllaris. Elongatus, fusco-testaceus pubescens, ca- 

 pite nigricante fortiter punctate, thorace latitudine breviore convexo 

 confertim punctato, vage biimpresso, lateribus rotundatis, augulis anticis

Florida; Dr. J. B. Bean. Only males obtained. The antennas 

 are strongly serrate, the third joint is as wide but scarcely half as 

 long as the fourth ; the last joint of the maxillary palpi is slightly 

 triangular, and as long as the preceding. The front part of the 

 thorax is sometimes fuscous. 



Anachilus differs from Cebrio by the entire absence of any 

 suture between the labrum and front ; the anterior margin of 

 the head is quite rectilinear. The feet are as in our North Ame- 

 rican species of Cebrio.
