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

 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.
