apex; antennae inserted at middle of rostrum, 

 i. Head, together with rostrum, and thorax entirely 



red ; elytra dark E. TIBIDIPEX> T IS, Ste^h.

R. viridipennis, Steph. (rujicollis, Panz., nee L. ; Salpingus 

 rujicollis, II. R. "NY., &c.). This species at first sight very much 

 resembles the preceding, but may at once be known by its entirely red- 

 dish-testaceous head and rostrum, and especially by the very much 

 shorter, broader, and differently shaped rostrum, which has caused 

 several authors to place it with Salting us ; in this case, however, 

 R. planifijiftris might also be removed to the same genus, as it is inter- 

 mediate as jegards shape of rostrum between the two species ; an tenure 

 inserted about middle of rostrum, fuscous, with base testaceous ; thorax 

 -trongly narrowed behind than irr R. nincolUs, L., didusely aud 

 coarsely punctured ; elytra bluish-green with distinct rows of punctures ;
