272 On a neio Genus q/" Buprestidse. 



The pelage of tlie head is of a bright flavous yellow, 

 passing into white around the circumference of the face 

 and into golden yellow at the point of the crest. All the hairs 

 of the summit of the head converge at the top to form a 

 pyramidal crest having exactly the form of a circus-clown's 

 peruke. The flavous yellow of the head passes into golden 

 yellow on the neck, then into brownish yellow on the upper 

 ])art of the shoulders, where this colour merges, almost in- 

 sensibly, at the height of the clavicles and the nape, into the 

 deep black of the chest and back. All the rest of the body 

 and the tail are of the same black above and below, with the 

 exception of the base of the tail and the outer part of the 

 thighs, where the black hairs are mingled with white — or 

 white-ringed — hairs which make this part of the body appear 

 as if covered with hoar-frost. The hairs of the back attain 

 a length of from 10 to 12 centimetres. The face, the ears, 

 and the naked parts of the fore limbs are of a bluish black. 

 On the face the eyebrows bear erect scattered black hairs, 2 to 

 3 cm. long; some fine whitish hairs, with rarer black hairs, 

 on the upper lip ; the chin is not bearded, but has a short 

 collar of flavous-yellow hairs, passing into brownish yellow 

 beneath the throat. The tail, which is long and slender, is 

 covered with rather short hairs. The callosities of the rump 

 are flesh-colour. The specimen is a female. 



Length of the body 45 cm. (circa) ; of the tail 80 cm.

Hah. According to M. le Docteur Marcel Leger, md lecin- 

 major des troupes coloniales, who has brought the skin with 

 the skull from Tonkin, this Semnopithecus is not rare in the 

 province of Cai-Kliin, to the north-east of Tonkin. 



XXXIV. — Description of a neio Genus of the Coleopterous 

 Family Buprestidje. By Chas. O. Waterhouse, I.S.O., 

 F.E.S. 



Some years ago I described in the ' Biologia Centrali- 

 Americana ' (Coleopt. iii. 1, p. 28) a species of Buprestidaj 

 under the name of Sphenoptera ptirpurascens, from Honduras. 

 I pointed out at the time that it differed from typical Spheno- 

 ptera in having a small scutellum. 1 have recently re- 

 examined this specimen (unfortunately unique), and have 

 come to the conclusion that it should be separated as a 

 distinct genus and be placed near Cinyra.
