 quite yellowish and the base of metatarsus likewise ; front tibiæ with 

 a bristle above, and middle tibiæ with two well developed antero- 

 dorsal bristles; hind tibiæ with the bristles stronger than in the male. 

 The squamular fringe darker than in the male, generally blackish.

 Odense (H. J. Hansen) ; only eight specimens in all. My dates are

 meadows in woods. 



Geographical distribution: — Europe down into Italy; its northern 

 limit lies in Denmark, and it occurs in England. Macquarthas recorded 

 it from the Canary Islands, but according to Becker (Mittheil. zool. 

 Mus. Berl. IV, 1908, 48, 70) this record is very doubtful.
