2. hiculor, Jur. Hj^m. pi. xiii. 



Very like the above, but distinguishable at once by the 

 narrow carinated petiole, the almost impunctate body, 

 the red 3rd segment (at least at the base), and the red 

 colour of the tibi^ and tarsi, which are only clouded with 

 black in the middle. 



Length 7 — 9 mill.

3. equestris, Fab. (nee Shuck.) Syst. Piez. p. 182. 



Extremely like hicolor, but has the mesothorax more 

 strongly punctured, the sides of the mesothorax below the 

 wings deeply and distinctly punctured, whereas in hicolor 

 their puncturation is hardly visible, and the petiole of 

 the body shorter and less distinctly carinated.
