Coh'optera from the Island of Hainan. 351 



antennae are of the same luteous-white colour as in the pre- 

 ceding species, and each ring embraces the apex of one joint 

 and the base of the next, beginning from the apex of the 

 third joint ; but there is a ring also near the middle of the 

 eleventh joint. The mesosternal process is not very promi- 

 nent, its anterior face being perpendicular and the lower face 

 {tlmost horizontal, so that the angle between these two faces 

 is very nearly a right angle. 



This species and the preceding one seem to be most nearly 

 allied to M. imitator^ White, from Shanghai ; but the latter 

 differs from them not only in the size, number, and colour of 

 the elytral spots, but also in having a much more feebly 

 developed mesosternal tubercle, 



14. Melanauster chmensisj Forst. 

 One example. 



15. Coptops polyspUa, Pasc. 



One example. The pubescence in this example has a 

 slightly reddish tint resembling that of C. rw/W, Thoms., from 

 the Andaman Islands, but in other respects it resembles the 

 type of C. pohjspila. Coptops petecMalis, Pascoe, from 

 Cambodia, and C. lacertosa, Pasc, from Penang, seem to be 

 specifically identical with C. polyspila, the type of which 

 came from Penang; and these three forms are probably only 

 varieties of the Indian species Coptops leucostictica, White.
