I had referred the solitary example of this species brought home by Mr. Belt to - 
Rh. venezuelensis, Chevr. Further examples from Guatemala and Costa Rica show -. ~ 
that it differs constantly from that species by the prothorax being pale red underneath, 
the posterior portion near the insertion of the anterior legs being clothed with silky 
golden or ashy pubescence. It is, besides, a distinctly narrower insect.
