are described ; while many more are scattered in European 

 collections without names. 



In the British Museiim we have not a few, principally 

 brought over by Hugh Low, Esq., Arthur Adams, Surg., 

 R.N., and other officers of H.M.S. " Samarang." It would 

 take a long time to get these together, and to describe them, 

 and so far as Crustacea go, Mr. Adams and the writer of 

 this notice are engaged in describing them, and in figuring 

 the new species. 



As a sample of the Coleoptera of the island, the two 

 following fine species may be described, more especially as 

 the accompanying figures will make these descriptions 

 plainer. 



It is only with a very limited and narrow portion of the 

 coast that we are yet acquainted, and even of this part the 

 productions are but very slightly known : much, however, 

 is expected from the energy of Mr. Brooke and the Colonial 

 Secretary; while the enterprise and curiosity of colonists 

 will soon make us better acquainted with the animals, and 

 add to our too limited collections. 



I subjoin the descriptions of two very fine Coleoptera, 

 sent by Mr. Low, with several other Borneo insects. 



Family LAMIAD^E. 

 Genus SAROTHROCERA, White. 



The antennae in this genus have the basal joint thick, 

 and furnished at the end on the inside with a tuft of hairs ; 

 the second joint is very small, with one or two hairs ; the 

 third to the seventh joints are fringed behind with longish 

 hairs, those on the third and fourth joints very thickly 

 distributed, and extending over a considerable part of the 

 hind edge. 



The Thorax is almost as long as it is wide, the sides are 

 nearly parallel, somewhat depressed above, with a short spine
