These beetles are small insects, with the head hidden under the thorax; they have filiform, pectinate or slightly clubbed antennae; and several species are world wide in their range, for as they live in all kinds of dried food stuffs they are easily introduced into new countries. _Gibbium scotius_ is a curious little beetle hardly over ¹⁄₁₂ of an inch in length, with a bright shining brown body, and the legs and antennae covered with yellow scales; it feeds upon feathers, and is often found in birds’ nests. _Anobium paniceum_ is known as the “Biscuit Weevil,” but feeds upon all kinds of things; I have found it in boots, seeds, drugs, botanical specimens, and it is said to have been found burrowing through sheet lead. The Cigarette Beetle, _Lasioderma serricorne_, is another little brown beetle common in Sydney in waste tobacco. Olliff has described a number of Australian species (Proc. Linn. Soc. N.S.W. 1886); and Westwood others (Ent. Soc. 1869), among which are several members of the Genus _Ectrephes_, which live in ants’ nests.

[Illustration: =Fig. 76.=--_Lyctus brunneus_ (Douglas). The Beetle so destructive to Rattan furniture. (“Agricultural Gazette,” N.S.W.)] Though small in size and number of species, these are very important beetles on account of the damage they do to rattan furniture and sapwood in unseasoned timber. _Lyctus brunneus_, a small elongated, reddish brown beetle about ⅙ of an inch in length, lives and breeds in wood, and is only too common about Sydney. A second species has been described from South Australia by Blackburn. Family 37. Auger Beetles. BOSTRYCHIDAE. [Illustration: =Fig. 77.=--_Bostrychopsis jesuita_ (Fabr.).
