344 Mr. F. P. Pascoe on some new or little-known 



Cereopsitts [Lamiidae]. 



Head narrow, quadrate in front. Antennas longer than the body, setaceous, 

 arising from two approximate tubercles, the basal joint elongate, nearly 

 cylindrical, the third longest, the remainder gradually decreasing to the 

 tenth, the eleventh as long, or a little longer. Eyes deeply emarginate. 

 palpi slender, the last joint elongate, ovate. Prothorax small, trans- 

 verse, narrow in front, gradually expanding into a strong spine, at the 

 side, near the base ; the spines more or less connected by a transverse 

 ridge, contracted at the base. Elytra trigonate, convex. Legs short ; 

 tarsi narrow, the basal joint scarcely longer than the second, claw-joint 

 elongate. Prosternum simple, slightly compressed ; mesosternum pro- 

 duced anteriorly. 



Cereopsius was a MS. name in use at the British Museum, and 

 adopted by me a few years ago, but has not been published to the 

 present time. The genus is allied to Monohammus, differing from it, 

 however, in many characters, as the approximate antennoe, elongate 

 and nearly cylindrical basal joint, the terminal joint also scarcely 

 longer than the preceding one, in the form of the prothorax the 

 whole side swelling out to form the spine, which is placed behind 

 the middle, the trigonate elytra broadest at the base and rapidly 

 receding towards the apex, and, lastly, the shorter legs. 



To Cereopsius must be referred the following Monohammi of Newm. : 

 M. Elpenor, M. Qucestor, and M. Lictor. The first of these is a nearly 

 unicolorous form of M. Prcetorius, Erich. One of the handsomest of 

 the species has been figured by Mr. White, in the 'Proc. Zool. Soc' for 

 1858 (pi. 53. f. 7), under the name of Cereopsius Helena. C. exoletus, 

 C. marmoreus, C. patronus, and C. histrio have been described by me 

 in the ' Trans. Ent. Soc.' (2nd ser. iv. and v.). It will be necessary, 

 however, to form a new genus for the latter. 



Imantocera [Lamiidae]. 

 J. Thomson, Arch. Entom. i. p. 188. 



Imantocera arenosa. 



I. fusca, fulvescente adspersa ; prothorace subtransverso ; antennarum arti- 

 culis septem ultimis unicoloribus. 



Hab. Cambodia. 



Pubescent, dark brown, sprinkled above with pale-fulvous more or 

 less confluent spots ; head with a deeply impressed line between the 

 eyes; antenna? about one-third longer than the body in <$, shorter in 

 $, the basal joint naked, robust, roughly punctured, the rest with a 

 pale-fulvous pubescence, the third and fourth joints in both sexes 

 dilated at the apex, with a thick tuft of hairs, confined to the upper
