Belongs to Group VII. This species differs from the others with 

 10-jointed antennae in having the head more transverse, the last joint 

 of the maxillary palpi short and oval, and three foveae present at the 

 base of the elytra. 



After the Plate for this paper was finished, it occurred to me that 

 C. malayanus may possibly prove to be the ^ of C. sericeus Kaffr., 

 fromPenang (Eev. d'Ent. XIV, p. 57, 1895) ; but C. sericeus has only 

 7 joints to the antennae. Raff ray placed it provisionally in Group VI, 

 next to C. shnilis Raffr., from Sumatra, in which the antennae are 

 similarly formed in the two sexes. I have tried to correspond with 

 Mons. Raffray about this matter, but have been unable to get any reply, 

 probably owing to the war. If this Penang insect should prove to be 

 the (^ of C. sericeus, it will be most intei'esting, as up to now no ? ? 

 are known for these forms with 10-jointed antennae.
