1 64 THE HUMBLE-BEE 



VIII 



Berkshire at Streatley. Other localities are 

 Shotover, Oxfordshire, and in Berkshire, Tubney, 

 near Abingdon, and Charlbury (Hamm) ; Boxmoor, 

 Herts (Piffard); Wicken, Cambs, on comfrey 

 (Nevinson) ; Brighton Downs (S. S. Saunders) ; 

 Croydon and Ipswich (Rothney) ; Barton Mills, 

 Suffolk (Perkins) ; Rugby (Morice) ; Yarm, 

 Yorkshire (Rudd) ; Carlisle (Heysham) ; in Ayr- 

 shire at Barr, Kilkerran, and Dundonald (Dalglish); 

 in Stirlingshire at Kilsyth, and in Lanarkshire at 

 Elvanfoot. A male from the last-named locality in 

 the Saunders' collection has the tail darkened by the 

 admixture of black hairs, except a small spot in the 

 middle. 



On the Continent the coloration of this species 

 varies greatly. The yellow bands are sometimes 

 absent, and a variety in which the tail in all sexes is 

 red, is, in many places, commoner than the white- 

 tailed form.
