Kga, on slender branches ; rare. 
Group Tapeinine *. 
Genus Tapreina, Serville. 
Serville, Enecyel. Méthod. x. p. 545. 
Body oblong, extremely depressed, clothed with erect hairs. 
Head broad and short, the lower part not being prolonged be- 
low the eyes, and the front edge of the crown in the female 
either forming a transverse ridge a little above the labrum or 
sloping to the epistome, and in the male elongated laterally into 
projections of various forms according to the species. Antenne 
longer than the body, stout, setaceous. Thorax transverse oval. 
Elytra rounded at the tip. Legs moderately short; thighs 
clavate ; tarsi short and broad ; claws divergent. 
The species forming this curious genus are found underneath 
close-fitting bark of trees, after they have been felled or uprooted 
in the forest. They share this peculiar habitat with the flattened 
Cucujidze, Nitidulids, Histeride, and others, all of which form 
together a somewhat extensive insect-fauna suited to these con- 
fined habitations.

* This group was placed provisionally under the Saperdite, in the 
synopsis previously given of the Lamiaires. A more accurate examination 
has convinced me that it has closer affinities with the members of the 
Desmiphorite. ‘The Tapeinz, in fact, appear to be abnormally flattened 
forms of Exocentrine.
