( 351 Xr. On the TenebrionidfB collected in Australia and Tasmania by Mr. James J. Walker, R.N., F.L.S., during the voyage of H.M.S. "Penguin," loitK descriptions of new genera and species. By George 0. Champion, F.Z.S. [Read Feb. 28th, 1894.] Plate VIII. It is proposed in this paper, whicli is in continuation of one contributed by Mr, Gahan on the Longicornia (Trans. Ent. Soc. Lond. 1893, pp. 165 — 197), to give a list of the Tenebrionidse collected in Australia and Tasmania by Mr. J. J. Walker in the years 1890 — 1, during the voyage of H.M. Surveying-Ship " Penguin," reserving for the present the Cistelidse, Melandryidte, Anthicidse, and the remaining families of the Heteromerous series, and also the Tenebrionidse subsequently obtained by him in other places. The material examined has been for-warded by Mr. Walker partly to myself and partly to the British Museum, but the whole of the specimens collected have been examined. Some few species are represented in the Museum-set only (mostly single examples), and these are specially noted below. Five new genera and thirty-three new species are described out of a total of 110 species. All the new genera and thirteen of the new species are from Tasmania, the remaining species being from North-west or West Australia. Three genera have not hitherto been recorded frum the Australian continent, viz., Crypficus, Corticeus, and Palorus. Lyphia {■= Lindia, Blackb.) is new to the Tasmanian fauna. Judging from the collection made by Mr. Walker, there is still much to be done in Tasmania, not only in the Tenebrionidae, but in the other families of the Coleoptera. I am indebted to the Rev. T. Blackburn for a good deal of assistance in the pre-paration of this paper, for the purposes of which I have carefully studied the collections of Pascoe and F. Bates — both very rich in Australian species, and containing a large number of Australian types, — and also the Hope Collection at Oxford. TKANS. ENT. SOO. LOND. 1894. PAKT II. (JUNE.)
