Family LIV. Melasomata Larr. Body often apterous. An- 
tenne scarcely longer than head and thorax conjointly, inserted 
under the exsert margin of head, mostly short, moniliform, with 
second joint short, third in most elongate. Internal lobe of maxilla 
almost always armed with a horny tooth or claw. Mandibles bifid 
or emarginate at the apex. 
Most of these beetles have a black colour ; others are brown or 
grey, without contrasting spots; they are shy of the light and 
live almost all on the ground, where they conceal themselves 
in corners or under stones. The shield-covers of the wingless 
species are grown together, and at the sides bent downwards.
