Tril.o V. CYBOCEl'IIALINI. 



This tribe is represented in our fauna l)y the single genus: 



XIX. CvBOCEPHALrs Erichs. 1844. (Gr., "inflected + head.") 



It comprises two miiuite species, the smallest of the family, hav- 

 ing the tarsi 4-jointed ; antenna.' scarcely h)nger than the width of 

 head; prosternum acutely earinate in front, not prolonged behind 

 the front coxae; thorax margined at base, covering the base of ely- 

 tra; body retractile and when so bent, ovate and very convex. One 

 of the two occurs in Indiana.

 lucent, surface smooth. Elytra with very fine, sparse punctures in basal 

 area. Length 1-1.5 mm. 



Dubois County; scarce. April 29. Probably throughout the 

 State, but overlooked on account of small size, as the range is given 

 as "Michigan to Georgia." Occurs in colonies on fungus covered 

 logs. Resembles in foi'in the species of A(jailu<lium of the family 

 SilphidJB.
