I am at a loss therefore to explain the signification of the 

 phrase " prothorax .... medio biplagiatus '"' which occurs 

 in Thomson's diagnosis. His expression " frons medio longi- 

 tudinaliter sulcata " is somewhat ambiguous ; it probably 

 refers to the groove between the antennary tubers, but this 

 groove is occupied posteriorly by a feeble median carina 

 which extends back between the eyes. This is no doubt the 

 species figured in the ' Indian Museum Notes ' (vol. i. no. 2, 

 pi. V. fig. 3) under the name Neoceramhyx holosericeus ^ Fabr. 



9. jEohsthes sinensis, sp. n. 



Prothorace lateraliter in medio subangulato ; dorso omuino intri- 



cato-rugoso, sulcis duobus obliquis impresso. 

 Long. 25-30 ram. 



Hab. China {J. G. Bowring, Esq.). 



This species is allied to velutina and somewhat closely 

 resembles it ; but the sides of the prothorax are somewhat 

 angulate in the middle in both sexes. The median space of 

 the pronotum inclosed between the two oblique impressions 

 is nearly as rugose as the rest of the surface and is almost 

 completely divided by a median longitudinal groove. The 

 elytra are somewhat darker in colour and present a more 

 rufiled appearance than in velutina. 



10. ^olesthes sarta. 



Pachydissus sartus, Solsky. 



The figure accompanying Solsky's description of this species 

 is inaccurate in making the elytra appear conjointly rounded 

 at the apex. They are described as truncate and somewhat 

 bispinose. If I am right in referring to it a specimen from 

 the Himalayas that I have seen, the species is quite distinct. 

 In this specimen, however, there is no median longitudinal 

 impressed line on the prothorax, and the third and fifth joints 

 of the antennjB are relatively a little longer than Solsky 

 represents them to be. In other respects it agrees exactly 

 with the description.
