of the Grouj) Ccrambycinoi. 255 



I am at a loss therefore to ox])lnin tlie signification of the 

 jihrase " |)rotliorax .... medio bii)higiatu.s " wliich occurs 

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

 tudinalitcr sulcata " is somewhat ambiguous ; it probably 

 refers to the groove between the antcnnary tubers, but this 

 groove is occupied posteriorly by a feeble median carina 

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

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

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



9. u:Eohsthes sinensis, sp. n. 



Prothorace lateraliter iu medio subangulato ; dorso omniuo intri- 



cato-rugoso, sulcis duobus obliquis imprcsso. 

 Long. 25-30 mm. 



Uab. China (/. C. Bowring^ Esq.). 



This species is allied to velutina and somewhat closely 

 resembles it ; but the sides of the prothorax arc 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 arc somewhat darker in colour and present a more 

 rutHed appearance than in velutina. 



10. JEolestlies sarta. 



Pachydissus sartus, Solsky. 



The figure accompanying Solsky's description of this species 

 is inaccurate in making the elylra appear conjointly rounded 

 at the apex. They are described as truncate and somewliat 

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

 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 antenn£e are relatively a little longer than 8olsky 

 represents them to be. In other respects it agrees exactly 

 with the description.
