 lata, maculis in elytris bifasciatim dispositis ; thorace breviter 

 cylindrico, supra aequali sparsissime punctato ; elytris versus basin 

 sparsim granulato-punctatis ; antennis tf eorpore multo longiori-

 cipue quarto, sexto et octavo) basi griseis. Long. 7-9^ lin.

Hiogo ; several examples. 



A large, elongated species, unlike Mesosa in facies, yet 

 closely allied to M. nebulosa. The head is concave, in the same 

 degree, between the antennas and the thorax, free from tuber- 

 cles; the antennas also have the eleventh joint nearly straight. 

 The elytra are greatly elongated in comparison with the head 

 and thorax ; they are of a light olivaceous-brown colour, varied 

 with greyish wavy marks, speckled throughout with dark 

 brown, and having a number of black marks — viz. one at the 

 base on each side, others at a third the length, arranged as a 

 broken undulated fascia, and others at two thirds the length, 

 also arranged as a much broken fascia, but with a distinct ob- 

 long spot on the suture. The thorax is similarly coloured, and 

 shows distinct traces of black lineoles on the anterior and pos- 

 terior margins. The dark spots are variable, and sometimes 

 obsolete. 



Rhodopis Lewtsu, n. sp. 



R. facie Monohammi, at minor. Elongata, nigro-fusca, pube brevi 

 ochraceo-fusca plagiatim vestita; capite tboraceque (angustis) 

 sparsim fortiter punctatis, hoc vittis tribus angustis ochraceo- 

 fuscis, tuberculo laterali brevi, conico ; antennis gracilibus, eor- 

 pore ( c?) triplo, ( 5 ) duplo longioribus, articulis 3°-ll um dimidio 

 basali pallidis; scapo pyriformi, <$ articulo tertio apice fortiter 

 clavato ; tibiis basi rufescentibus. Long. 6-7 lin. <S 2 • 



Hiogo ; many examples. 



Differs from the only other described species, R. pubera, 

 Thorns. (Sylhet), by the pyriform club of the antennal scape ; 

 this joint in R. pubera, according to Lacordaire's description, 

 being obconical. The lateral tubercle also seems to be more 

 distinct ; it is very short, however, and broadly conical. In 

 all other respects it answers well to the generic characters of 

 Rhodopis. The club at the apex of the third antennal joint 

 in the male is very similar in size and shape to the scape ; and 

 both are dark brown and glossy. The elytra are somewhat 

 evenly punctured throughout ; and the light brown macular, to- 

 mentose, pubescence is collected here and there into patches,
