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'"?
