7. E. quadriseta Villen.

This species I cannot discriminate from E. glauca. My material 

 has been determined by Villeneuve. The frons in the male is broader^ 

 nearly as broad as the eye; second antennal joint relatively a little 

 longer, and thus the frontal bristles scarcely reaching its end. The 

 black hind margins on abdominal segments a little narrower, and 

 the middle stripe less distinct, or wanting on fourth and fifth seg- 

 ment. According to Villeneuve the male genitalia are different, 

 but this I have not been able to examine. 



The species is not rare in Denmark; Ruderhegn (Kryger), Tis- 

 vilde and in Jutland at Kolding; the dates are ^"/s— Vs- 



Geographical distribution: — Europe down into France; not 

 known north of Denmark.

 protruding; orbits about as broad as frontal stripe; cheeks moderately 

 narrowing downwards. Orbits greyish; cheeks silvery; jowls grey; 



frontal stripe velvet black. Generally weak 

 outer vertical bristles present. Frontal 

 bristles descending to end of second an- 

 tennal joint, only the uppermost strong
