 Firs in July ; also plentiful at Rixton Firs in September 

 1899. Chesh.: Walton, Moore.

Syrphus corolla? F. Chesh.: Walton Arches, August 1897,. 

 abundant on Compositse. 



Syrphus tricinctus Fin. Lane. S. : According- to Dr. Meade 

 this handsome species is rare — he having- none in his own 

 collection. It occurs in Rixton Firs during- May, and I have 

 taken, I think, five specimens altogether. The dark colour 

 of its body makes it difficult to distinguish among the fir- 

 needles. Its bright yellow bars usually betray it, however.

 Hatchmere district, July 1897, several.

Volucella pellucens L. Chesh. : King's Wood, Delamere,, 

 July 1897, two ; Frodsham, July 1898, one. 



Eristalis intricarius L. Lane. S. : This species (both sexes) 

 was literally swarming round a large hawthorn tree, which 

 was in full bloom, in a clearing in Rixton Firs in the middle 

 of May 1897. Chesh.: I have taken it also at Moore in 

 the same month.

 side near Hatchmere, nth June 1899.
