Hah. Philippine Islands. 



Four specimens of this species liave been in tlie British 

 Museum since 1845, and M. Oberthiir possesses another 

 example. They are almost destitute of the earthy covering 

 usually found in these beetles, but this is probably only due 

 to local or accidental circumstances. The species is similar 

 to the preceding one except in matters of detail. It is rather 

 smaller and more slender, and the prothorax is everywhere 

 rather coarsely punctured, a few punctures being traceable 

 even upon the costre, which are rather thick. The rows of 

 punctures upon the elytra are rather less coarse than in 

 R. peninsularis. The pygidium and underside are as in that 

 species, but the middle femora are not toothed.

Jlah. LOUISIADE ARCHIPELAGO, Sud-Est Island. 



Three specimens were collected by Mr. Meek in April 

 1898, one of A\hich has been presented by M. Oberthiir to 

 the Museum. 



The species closely resembles R. i^hilippiacnsisj but is
