The above description is drawn up from two specimens, 
both females, of which one is now in the British Museum and 
the other in the Hope Department at Oxford. They were

Himalayas. 
‘The prothorax in this species is not costate, but furnished 
with one entire median groove and two tapering depressions 
extending from the base, where they are very broad, nearly to

This insect is allied to R. Taprobane, Fairm., from Ceylon, 
but with readily apparent differences. Besides being larger 
and more elongate, it is uniformly black with the exception 
of the legs, whereas the Ceylon insect has elytra of a deep 
chestnut-colour. In the latter, also, the elytra are rather 
difierently sculptured, the punctures being situated in definite
