61 REVISION OF AUSTRALIAN SPECIES OF THE SUB-FAMILIES GYPHALEINJE AND CNODALONIN.E. (Fani. TENEBRIONIDiE). By H. J. Carter, BA., F.E.S. (Plates vi.-vii.) The Cyphaleinse are almost entirely Australian, the only recorded exceptions being (a) the species of the genera Crypsis and Artactes from the Indo-Malayan Islands and Japan; (b) two species from New Guinea, described by Macleay as Prophanes, but which I consider to be Cyphaleus; and (c), a single species, Cyphaleus valdivianus Phil., from Chili. It is extremely pro-bable that more will come to light as the fauna of New Guinea is more thoroughly investigated, while the single link with South America is an interesting fact of distribution. Its members include the handsomest of all the Tenebrionidae, but endowed with strong powers of flight; and their habits and life-histories being almost unknown, comparatively few specimens are to be seen in ordinary collections. The subfamily presents strong evidence of belonging to an ancient but disappearing race, with its man}' genera and few species, and these sometimes not very closely related to one another. The Cyphaleince are distinguished from the Tenebrionince by the following characters. Head flat, more or less enclosed in the thorax, eyes large and transverse, mandibles bifid at the ex-tremity, antennae generally long, with joints G-10 successively enlarged. Prothorax generally Insinuate at apex and base, with the anterior angles well produced; the prosternum is in general strongly compressed or carinate, its process received behind into a wide cavity of the mesosternum. The intercoxal process wide, oval, or angular, tibiae with short spines, not usually enlarged at apex, tarsi long.
