290 CLASS INSECTA. 



remarked in any other insect. Their apparatus of generation 

 differs much from that of the carnivorous coleoptera. 



This genus is considerable. We divide it into five sec- 

 tions. 



The first, that of Fissilabra, has the head entirely naked, 

 and separated from the corslet, which is sometimes squared, 

 or in a semi-oval, sometimes rounded, or in a truncated heart, 

 by a neck, or visible strangulation. The labrum is deeply 

 divided into two lobes. Such are : — 



OxpoRus, Fab,, 



Of which the maxillary palpi are filiform, and the labial 

 terminated by a very large, and crescent-formed articula- 

 tion. 



The antennae are thick, perfoliated, and compressed. The 

 anterior tarsi are not dilated. The last articulation, and 

 next to that the second, are the longest. They live in fungi, 

 and agarics.

 19, about three lines in length, fawn-coloured, with the 

 head, the chest, the extremity, and the internal edge of the 

 wing-cases, as well as the anus, black.* 



AsTRAP^us, Grav., 



In which the four palpi are terminated by a larger and almost 

 triangular articulation. The anterior tarsi are very much 

 dilated. The first and the last articulations are the longest.-|-

 ricius belong to the sub-genera of our fourth section. See Olivier, Encyc.
