I am at a loss therefore to explain the signification of the 
phrase u prothorax .... medio biplagiatus 31 which occurs 
in Thomson’s diagnosis. Ilis expression u 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 c Indian Museum Notes s (vol. i. no. 2, 
pi. v. fig. 3) under the name Neocerambyx holosericeus , Fabr. 
9. EEolesthes sinensis , sp. n. 
Prothorace later aliter in medio subangulato ; dorso omnino intri- 
cato-rugoso, sulcis duobus obliquis impresso. 
Long. 25-30 mm. 
Hah. China (/. 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 
ruffled appearance than in velutina . 
10. JEolesthes 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 antennas are relatively a little longer than Solsky 
represents them to be. In other respects it agrees exactly 
with the description.
