spot above it. Supra-anal plate of the male with the outer margins 

 slightly convex, and the hind angles somewhat rounded, with four 

 tubercles in a transverse row and a tubercle in the basal sulcus. 

 Male cerci with the ascending part very feebly bent forward, equally 

 wide all along, obtusely truncate at the apex, a little more than 

 twice as long as the basal (descending) part. 



Dimensions of the type are as follows : Length of body 19 mm. ; 

 of pronotum 5 mm. ; of elytra 14-5 mm. ; of hmd femur 12 mm. 



Dimensions of one of paratypic females are : Length of body 

 22 5 mm. ; of pronotum 55 mm. ; of elytra 16 mm. ; of hind femur

(5*. Somewhat larger than R. crassus Walk., modei-ately rugose. 

 Frontal ridge parallel-sided, sulcate throughout, but obliterate just 

 before the cljrpeus. Fastigium of vertex about twice as broad 

 as the frontal ridge, very feebly impressed. Median keel of pronotum 

 feeble, especially so between the sulci; lateral keels feeble, but 

 subobliterate between the sulci only, almost reaching the hind margin 

 of the pronotum; disc feebly rugose; tubercles between the sulci 

 small; metazona with but a few small, scattered tubercles. The 

 last abdommal segment obtusangularly excised, the sides of the 

 emargination slightly sinuate. Supra-anal plate trapezoidal ; outer 

 margins straight ; hind angles a little more than 90°, not rovmded ; 

 median keel low and broad, widely bifurcate in the basal half, narrowly 

 sulcate in the apical part; a chitinous tubercle in the middle of 

 the basal impression ; two tubercles near the median keel, beyond 

 the middle; two smaller tubercles on the same line with the two 

 submedian ones, but close to the outer margins. Cerci with the 

 basal part thick, punctured; the apical (ascending) part not twice" 

 as long as the basal, slightly bent forwards and outwards; the 

 apex blunt, but not truncate, projecting only a little above the 

 supra- anal plate. 



General coloration bro^vnish-ochraceous, uniform. Elytra with 

 a few indistinct darker spots. Hind femora with the indistinct dark 

 fasciae on the upperside ; the whole inner side shining black, with a 

 very sharp, quite transverse pale rmg before the apex; the knee 

 brown, with the inner lobe pale and with a very narrow black ring
