402 CLASS INSECTA. 



Bytqrus, Lat. Schoen. Dermestes, GeofF. Fab. Oliv. Ips^ 



Oliv. 



A sixth tribe, that of Eiigidites, analogous to the last, as 

 to the emargination of the extremity of the mandibles, is 

 distinguished from them by their not jutting out, or but very 

 little, and merely at the sides, on the labrum. The body is 

 ovaliform or elliptical, with the anterior extremity of the 

 head a little advanced, in an obtuse or truncated point. 

 The tarsi have five distinct articulations, entire, and for the 

 most part a little hairy underneath. The penult is simply a 

 little shorter than the . preceding. The antennae are termi- 

 nated in a perfoliate knob, of three articulations. The 

 elytra entirely cover the abdomen. The palpi are a little 

 thicker at their extremity. Some species, very small , live in 

 the interior of houses, and they are often found behind the 

 panes of cross-bar windows. 



These clavicornes will be united into a single genus, that 

 of 



Dacne. 



Dacne (Proper), Lat. Engis, Fab. Dej. Erotylus^ Oliv. 



Their antennae are terminated abruptly, in a tolerably large 

 knob, orbicular or ovoid, compressed, composed of close arti- 

 culations, of which the middle one at least is much more 

 broad than long. The third articulation is longer than the 

 preceding and following. 



The middle of the posterior edge of the corslet is dilated 

 behind, or lobate, and the superior extremity of the chin is 

 advanced and terminated in a truncated or bidenticulated 

 point.
