Differs from R. rujieollis, Clk., inter alia, by its much more 

 strongly transverse prothorax and its much longer elytra. 

 R. viridi-cenea, Clk., is not described in a manner to allow of 

 very satisfactory comparison, but the present species is very 

 differently coloured, and the phrase " capite inter oculos 

 transverse foveolato " does not describe at all correctly the 

 sculpture of the head of the present species.' In R. ijnpressa, 

 Blackb., and brevipennis, Blackb., inter alia raulta, the prothorax 

 is very much more nitid and less conspicuously punctulate. 

 JR. rugulosa, Blackb., has very much more rugulose sculpture, and 

 R. excelsa, Blackb., besides being very differently coloured has 

 inter alia, a less transverse prothorax (its width to its length 

 down the middle as 8 to 5) which is traversed by a very strong 

 and conspicuous transverse sulcus.
