306 SUPPLEMENT ON THE FAMILY BllACIIELYTRA 



tera of this family. Many oxyteli are more particularly 

 found in the dung of animals, and human excrements. 

 Some others habitually frequent humid or aquatic situ- 

 ations. Others remain under moss, stones, &c. The males 

 of some are remarkable for two prominences in the shape 

 of horns, which they have in front of the head. Even 

 some among them have a strong and advanced point upon 

 the corslet. 



We have figured a species of Zirophorus, which M. La- 

 cordaire has called coriaceus. It is smooth, and of a greyish 

 black, with the antennae and legs black, and is nine lines and 

 a half in length ; also from Brazil. 



Next to the Zirophorus we will add a new genus, which 

 we call Trichocoryne. The characters are as follows : the 

 mandibles slightly dentated ; the antennae with the first joint 

 club-shape, and stuffed — the second and third slender, rather 

 clubbed, the other joints oblong-square ; the labrum small, bi- 

 lobed ; the labium large, crescent-shaped ; the maxillary palpi 

 with the last joint large and sub-oval ; the labial palpi small : 

 it is readily distinguished from the Zirophori, by the length 

 of the antennae, and its peculiar form, which is easily seen 

 by referring to the plate of dissections. This species is from 

 the West Indies. It appears to be the same as M. Dalman 

 described in his Anal. Ent., under the name of Zirophorus 

 penicillatus. The specific characters are, piceous, with the 

 antennae and legs reddish ; the elytra strongly striated ; the 

 length is three lines and a half. The type is in Mr. Children's 

 cabinet. 



The Omalia are also very small coleoptera, which in 

 their manner of living differ but little from the Staphylini, 

 from which they have been distinguished generically by 

 M. Gravenhorst. Some are found under moss and flowers ; 

 others delight in cow-dung and other excrements. Some 

 few live in agarics.
