 to the apex. 



R. cupreata may be known from the preceding by its narrower 

 and more parallel form.

 broader than the thorax, subparallel, scarcely excavated below 

 the basilar space, longitudinally sulcate within the humeral callus, 

 the latter subprominent ; striae strongly punctured in front, sul-
