( 89 ) XI. On New Genera and Species of Longicorn Coleoptera. Part II. By Francis P. Pascoe, Esq., F.LS, &c. [Read Jan. 5th, 1857.] Although the present communication is but the continuation of a former one read to the Society last March, 1 have somewhat en-larged its scope by not exclusively confining myself to the Longi-corns of Asia. From all countries there are numerous species and many new forms in our collections, still unnamed and unde-scribed ; and the more remarkable of these, I hope, from time to time, to bring under the notice of the Society. While expressing my acknowledgments elsewhere to gentlemen for facilities afforded me in one way or another, I cannot help tendering my thanks here to our president, W. W. Saunders, Esq., F.R.S., &c., &c., for his liberality in placing many fine and curious forms in my hands for publication, in addition to the numerous rarities with which he has enriched my cabinet. To Adam White, Esq., of the British Museum, I owe many valuable suggestions ; nor, without the facilities afforded by that now really noble institution, both in its museum and library, would it be possible to ascertain what had been done by naturalists, who have scattered their writings about in every imaginable form of publi-cation. The life-like drawings of the more remarkable forms here described, from the well-known pencil of J. O. Westwood, Esq., leave nothing to be desired, and I can only regret that the exigencies of the situation do not allow me to avail myself still further of his skill. To avoid repetition it is to be understood that all described in this paper from Malacca and Borneo are due to the researches of Mr. Wallace ; and when Mr. Low, a professed naturalist and resident in the latter country, tells us in his work (" Sarawak," p. 87) that " beetles* are very scarce," it may be inferred by those who have seen, from time to time, the extensive collections sent to this country by the former gentleman, with what energy * Why not gel rid of this word, which is not confined, in common parlance, to the Culeoptera, and is almost universally applied to the cockroach only, by the vulgar'! We have " mammal" and " mollusc" naturalized among us recently — why not " colcop'"?
