each elytron, the second is a little behind the middle, while a 

 third very indistinct band is placed a little before the apex. 



This species, which is allied to, and somewhat closely resem- 

 bles Coptops aedificator, Fabr., C. fusca, Fabr., and other species, 

 may yet be sufficiently distinguished by the broad and distinct 

 dark-brown band on each side of the prothorax, taken together 

 with the other characters detailed above. I have named it in 

 memory of Mr. Pascoe to whose labours we are indebted for 

 the descriptions of most of the known species of this difficult 

 group. 



The species has hitherto been known only from Siam and 

 Cambodia.

Mesolophus, g. n. 



Head strongly enough concave between the antennal tuber- 

 cles. Eyes sub-divided. Antennae (9) longer than the body; 

 the scape elongate, a little shorter than the third joint; the latter 

 slightly curved, longer than the fourth, the following joints 

 gradually decreasing in length. Prothorax transverse, unarmed 

 at the sides. Elytra moderately long , subacute and minutely 

 tubercled at the shoulders, from tlience narrowed posteriorly; 

 apices broadly and somewhat obliquely truncate, with the outer 

 angles obtusely rounded off; each elytron with a short pro- 

 minent crest placed a short distance back from the middle of 

 the base. Prosternai process with its posterior face vertical, its 

 postero-inferior edge, which is somewhat obtusely pointed in the 

 middle, projecting slightly backwards; the mesosternal process 

 is strongly declivous or almost vertical in front, its ventral face 

 is very short and is slightly raised along the middle. The legs 

 of the female are sub-equal in length; the intermediate tibiae 

 entire; the claws of the tarsi divergent. 



This new genus of the Mesosides resemhles Aesopida in having 

 a basal crest on each of the elvtra, but this crest does not
