315 XX. RemarJcs on the Genus Ectrephes^ and Descriptions of new Exotic Coleoptera. By J. O. Westwood, M.A., F.L.S., &c. [Read 7tli June, 1869.] Genus Ectrephes, Pascoe. E ctrephes, F&acoe, Proc. Ent. Soc, Lond. 1866, p. xvi; Zoologist, ser. 2, vol. i. p. 322. Anapestus, King, Trans. Ent. Soc, N. S. Wales, i. 316. Mr. Pascoe^s description of this curious genus was read at the meeting of this Society, on the 4th June, 1866, and was published in the following month. Mr. King's memoir was read before the Entomological Society of New South Wales on the 5th March, 1866, but the sheet of the Transactions on which it is printed contains the commencement of Mr. McLeay's paper on Amycteridce, which was read on the 6th August, 1866, and Part V. of the Transactions, in which both papers appeared, con-tains the Journal of Proceedings for the 3rd September, 1866. The genus has been considered to be allied to the Paussidce, as well as to the genus Gnostiis. But it pos-sesses no direct affinity with either of these groups; and is proved, by the analysis of the forms described below, to be most nearly related to the Ptinidce, especially to such groups as Mezium and Gihhium.
