have rather damaged tlie specimen, but still not so as to entirely 

 destroy the beauty of this remarkable biitterfly. No lepidopterous 

 insect of its magnitude has hitherto been known from the locality of 

 this species ; which, from the other insects contained in the šame 

 box, is supposed (as no memorandum was sent with it) to be either 

 Solomou Islands, Aneiteum, New Hebrides or the Fiji group, — at any 

 rate from one of the islands in the South Pacific Ocean. 



The figure (PI. XXXIX.) represents it of its natūrai size. The 

 general colour is glossy bronze-black, with the two outer rows of 

 irregular-sized spots of pure white, while those at the base of the 

 fore wings are rich king-yellow, but partly pure white outerly ; the 

 anterior margiu of the secondary wings narrowly bordered with king- 

 yellow. 



The under surface likę the upper ; but the anterior margin of the 

 secondary •vvings broadly bordered, and some of the spots tinged, 

 with rich king-yellow. The head and thorax pure black ; the body 

 ochraceous yellow above, and black aloug the middle beneath. 



It is a female. The malė remains at present unkuown, but one 

 may suppose, by the usual brilliancy of the malęs of this group to 

 which it belongs, that it is likely to prove a most beautiful insect, 

 eshibiting some gorgeous combiuation of colour. 



The name I propose for this splendid insect is Papilio {Ornitho- 

 l^tera) Fictorice, 



3. Descriptions of some Coleopterous Insects in the 



COLLECTION OF THE BrITISH MuSEUM, HITHERTO APPA- 

 RENTLY UNNOTICED. By AdAM WhITE. 



(Annulosa, PI. XL. XLI.) 



The number of "new species" of Coleopterous Insects in the 

 Museum collection is in relative proportion to the great richness of 

 the other brauches. In this paper, some species belonging to the 

 fauiilies Prionidce, Lamindce, and CetoniadcB 'vnA be given, as there is 

 every likelihood, from the way in which these great groups have been 

 investigated by Messrs. Serville, Burmeister, Schaum, Gory, and 

 other entomologists, that the species are as yet unrecorded in scientific 

 \vorks ; it is to the kindness of Dr. Gray, the keeper of the depart- 

 ment, that I am indebted for pennission in laying these descriptions 

 before the Society. 



Tribe LoNGicoRNiA. 



Family Prionid^. 

 The Prionidce consist of several marked subfamilies, in one of 

 which we would place Trictenotoma, G. R. Gray, one of the most 

 interesting of the genera of Beetles. This form, which appears to 

 me to be altogetlier Longicorn, is chiefly remarkable for its hetero- 

 merous tarsi, and for the ninth and tenth joiuts of its anteųnae being 

 serrated or produced at the end, ahnost as iu the Lucimidce. It is 

 one of thosc "aberrant" forms which naturalists call "anuectent,"
