Type of R. armatus in the British Museum. 



The male characters and the sculpture of the head will serve to 

 distinguish this insect from all the other Indian species. The 

 two most nearly allied species are R. strains, Newm. (from the 

 Malay Archipelago) and R. crassiusculus, Lewis (from Japan), 

 both of which resemble R. aterrimus in the sculpture of the head 

 and the armature of the male.

Elongate, shining, pitchy black ; head narrowed before the 

 eyes, with two deep furrows which meet in a curve behind ;. 



antennae with the joints transverse, the last 

 ones being pilose ; prothorax somewhat 

 ovate, truncate at base, with three furrows, 

 the lateral ones being much the broader, 

 marginal furrows deep and narrow, the 

 two central carina? narrower at the base 

 and slightly separated in front, where they 

 enclose a narrow space, but this is variable ; 

 elytra with row r s of strong punctures, but not 

 strongly striate except for the sutural stria, 

 which is deep with scarcely visible punctures^ 

 fourth interstice strongly raised at apex, 

 the raised portion curving round to the 

 suture and giving the impression of a large 

 depressed space before the apex, which is 

 more distinct than in some of the allied 

 species ; ventral segments with single series 

 of strong punctures ; anterior tibiae with 

 Fiff. 234. two snar P teeth before apex.

It seems most probable that the above synonymy is correct, 

 R. punctatostriatus having been described by Motschulsky from 

 Ceylon. Grouvelle (Rev. d'Eot. xxii, 1903, p. 97) introduces a 

 R. punctatostriatus from Sumatra into his table of species, but this 

 is really R. punctatolineatus, described by him on page 116, and he 

 has simply made a mistake in the names ; it has nothing to do 

 with Motschulsky's species. Grouvelle himself has corrected
