Mr. A. White on new species of Longicorn Beetles. 47 



tained in them. The spores are obovate, surrounded by a narrow 

 pellucid border, containing a subtle granular substance. The 

 outer coat of the fruit or perisporium which contains the above- 

 described filamentous nuclei is formed of cells, somewhat large, 

 flaccid and elongated, adhering to the membranaceous stratum, 

 transparent and rose-coloured. 



I shall conclude by protesting that I do not wish to constitute 

 myself the censor of others, but it appears to me that the cha- 

 racters adopted by Kiitzing in the formation of the genus Myelo- 

 mium arc rather too incomplete, and that the name of Ginnania, 

 proposed anteriorly by the excellent Montagne and supported by 

 the strongest arguments, will nevertheless be preferred at the pre- 

 sent day, inasmuch as the caprices and partialities of authors 

 ought not to be sanctioned in contravention of the laws generally 

 agreed on by botanists. 



VII. — Descriptions of four apparently new Species of Longicorn 

 Beetles in the Collection of the British Museum. By Adam 

 White, M.E.S., Assistant in the Zoological Department of the 

 British Museum. 



[With a Plate.] 



Sarothrocera, White. 



Antenna with the first joint thick, and furnished at the end on 

 the inside with a tuft of hairs; second joint very small, with one 

 or two hairs ; third to the seventh joints behind fringed with 

 longish hairs, the hairs on the third and fourth very thickly dis- 

 tributed and extending over a considerable part of the hind edge. 

 Thorax almost as long as wide, the sides nearly parallel, some- 

 what depressed above, with a short spine on each side. Scutellum 

 somewhat elongated, the sides parallel. Legs with the femora 

 compressed, especially above ; the tibiae much compressed, slender 

 at the base, getting thicker towards the middle, and from that to 

 the end wide, with the sides nearly parallel. Tarsi very wide. 

 Elytra strongly angled, almost aculeatedon the shoulders, rounded 

 and simple at the end. 



This genus in the system comes close to Cerostema, Dej., with 

 which and Batocera it has some characters in common. 



The species is from Borneo, whence it was sent by Hugh Low, 

 jun., Esq., after whom I have named it. 



Sarothrocera Lowit, White. PI. I. f. 6. Of a rich brown, 

 slightly tinged with ochraceous ; the hairs on the antennae are of 

 a very dark brown or black ; the scutellum is of a pale yellow ; 

 the base of the elytra is finely verrucose above, the small warts
