neckcloth. Antennas thicker towards their extremi- 

 ties. 



Division I. 



Tarsi with five very distinct articulations. 



Subdivision 1. 



Antennae straight, not inserted in the cavity of the 

 eyes. Feet perfectly contractile. Mandibles but little, 

 or not at all, prominent.

 Lam. Latr. 



Byrrhus. Linn. Marsham. 



Dermestes. De Geer. 



Antennae shorter than the thorax, with the club solid. 

 Palpi filiform, short. Body orbiculate ovate. Scutellum 

 very minute. 



Sfi. 1. Scrofihularie . Black ; sides of the thorax, and 

 three transverse bands on the elytra, grey ; suture and 

 external margin of the elytra, and hinder margin of the

Genus CXXVII. Throscus. Latr. 



Elater. Linn. Olivier, GeofTVoy. 



Dermestes. Fabr. Paykull, Illiger. 



Antennae as long as the thorax, with the three last 

 joints large, forming an oval club. Palpi short, with the 

 last joint securiform. Body elliptic, narrow, depressed. 



Obs. This genus probably belongs to the tribe Ela- 

 terides, from which it differs but in the structure of 

 its antennae.
