Fig. 13. Wing of E. aulicus d"- 



the first posterior cell broadly open ; anal vein not reaching the 

 margin. Squamulæ yellow, with a fan of dark yellow bristles. Balteres 

 yellow. 



Female. Epistoma broad, grey. Antennæ shorter than in the 

 male. Middle tibiæ with a strong bristle in the middle on the ventral

E. aulicus is rare in Denmark, and almost all specimens have 

 been taken many years ago; Amager (Stæger, Jacobsen) and on Born- 

 holm at Allinge (H. J. Hansen); on Amager it was found in no small

 both localities seem to indicate, that the species lives near the coast, 



Geographical distribution : — Most Europe, and in Asia minor ; 

 towards the north to middle Sweden.

 likewise strong, they are interrupted in the middle, as there are no 

 bristles above the oral aperture, but they are represented by fine, 

 short hairs. Antennæ short, or the basal joints elongated; they are
