TENEBRIO, in Entomology, a genus of the Coleoptera 
order of insects, the generic character of which is, that the 
antennae are moniliform, with the last joint rounded ; the 
thorax plano-convex, margined; the head exserted, and 
wing-sheaths stiffish. 
In the insects of this genus the body is oblong-oval, and 
and in most species somewhat pointed at the extremity. 
Several species are also destitute of wings. This is a numer¬ 
ous genus, and is divided by Fabricius Xmd others into seve¬ 
ral distinct genera, under the appellations of Pimelia, Bleps, 
Aturnus, &c. In Gmelin’s edition of Linnaeus it compre¬ 
hends 63 species.
