This species has frequently been taken in hiberation as is shown 

 by the above records. Mr. W. J. Gerhard found the species fairly 

 abundant about electric lights in the suburbs of Chicago during July 

 and August, 1914. Probably the majority of all specimens collected 

 have been taken at lights or in hibernation. Nothing is known regard- 

 ing the life history altho the general scarcity of specimens and the 

 wide distribution of the species suggests that it is predaceous in habits. 

 Blatchley (1895) records two specimens that "were found beneath 

 the bark of a black oak log {Oiierciis coccinea iiuctoria (iray) which 

 lay on the side of a high sandy hill near the Wabash River. Feb. 

 19, 1893." 



Renter (1876) described histrio and erected the genus Callicapsus 

 for its reception, recording the locality as "Texas" and "Carolina." The 

 type specimens are probably still to be found in the Stockholm Na- 

 tional Museum. In a later examination of the species. Renter (1909) 

 placed it in Camptobrochis, pointing out that structurally histrio dif- 

 fers very little from pnuctulatns Fallen and other closely related species.
