Hab. India. 



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 

 collected by Capt. Boys, and, although no record has been 

 kept of the part of India in which they were found, there 

 is good reason for supposing them to have inhabited the 

 Himalayas. 



Theprothorax 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 

 the middle. It resembles R. niponcnsis, Lewis, but is more 

 depressed, the elytra more deeply sculptured, and the elevated 

 ridges at the apex of the latter much longer, extending about 

 a quarter of their length. The anterior femora are not 

 toothed in the female.

(Several specimens were collected by Mr. Doherty and 

 presented to the British Museum by Mr. George Lewis. 

 This insect is allied to R. Taprobance, Fairra., from Ceylon, 

 but with readily apparent differences. Besides being larger 

 and n)ore 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 

 diflerently sculptured, the punctures being situated in definite
