The abdominal plates are a little more than two-thirds the 

 length of the basal segment ; they are punctured finely and closely 

 (like the adjacent surface), and also bear some large sparse punc- 

 tures. The flattened ridge of the prosternum is narrowed from 

 its base to the front, which is rounded. The underside is closely 

 and finely punctured laterally, the metasternum being nearly 

 impunctate in the middle — the ventral segments in the middle 

 more coarsely and less closely punctured than at the sides. 



A large robust species bearing much superficial resemblance to 

 my R. australis — from which it differs (apart from the structure 

 of the prosternum) in its generally superior size and robustness, 

 the stoutness of its tarsi, and in the epipleurae of the elytra being 

 dark piceous, whereas in every specimen that I have seen of 

 R. australis they are of a bright ferruginous colour, concolorous 

 with the general surface of the underside. The pubescence, 

 moreover, is of a rich golden brown, and in R. australis is pale 

 brownish white.

* This description I have accidentally misplaced in the memoir ; it should fol- 

 low the description of R. cyanejis on p. 200. Owang to this accident I have 

 also omitted the species from the tabulation on p. 203 of species with the pros- 

 ternum longitudinally flattened. In the tabulation R. major would fall among 

 the oval species but is distinct among them by its much greater size and other 

 characters.
