 injury to s{)routing corn in Texas 

 by this beetle has lately been re- 

 ported by a correspondent of the 

 I'. S. Bureau of Entomology, in- 

 volving a loss of about nine 

 tenths of the crop on fifty acres 

 })lantcd. It has been noticeably in- 

 jurious to planted seed-corn in several Illinois counties during the spring 

 of the present year (1905). It may well be called the seed-corn beetle. 



A remarkable chfitrge of injury to corn has been made against Otyio- 

 phron labiatum (Fig. 172). The ground-beetles of this genus live in wet 

 sanely places, es])ecially along shores, and are usually predaceous. The 

 subfamily Carahincc, to \vhich they belong, is otherwise exclusively 

 predaceous so far as known. The Omophron beetles are hemispherical, 

 and quite unlike typical ground-beetles. The larva of this sjiecies, 

 which is not known to 

 occur in Illinois, is said 

 to be very destructive to 

 young corn in the South- 

 ern States. One author 

 says that it feeds on the 

 grains, and another, on 

 the young shoots. 



The adult ground- 

 beetles usually winter 

 over; sometimes, perhaps, 

 the larvae. Eggs of some 

 species are known to be 

 laid in early summer in 

 the ground. The larva) 

 live in burrows and ma- 

 ture in the latter part of 

 the season. They are rath- 

 er long-legged and active, 

 whitish to brownish , some- 

 times more or less black. fouiVhinciT.'
