Walker's figure of the type (PI. 8, fig. 2) has nothing to do 

 with his description. Melichar has figured R. vitriccps (Stal.)

 the Bornean (from which it dift'ers abundantly otherwise) by the

 base of abdomen sanguineous in fresh example), rostrum, sterna, 

 legs etc., paler. Tegmina and wings hyaline, iridescent ; veins 

 testaceous, faintly infumate broadly on each side of most of the 

 transverse veins of the tegmina. Four tiny black specks on the 

 radial vein. The subapical line is a little more irregular than in 

 R. vitriccps. 



Length: 2|- mill to apex of abdomen, 4^-4! to apex of teg- 

 mina.
