blue-black, lanceolate, and having the two basal segments clothed 

 with white pubescence, most densely so at the sides. B.M. 



This beautiful species appears near London early in April ; but I 

 once took it on the 22nd of March, and in Yorkshire I have found 

 it plentiful in July ; it frequently burrows in trodden pathways. 

 I never observed any parasite entering its burrows : neither have I 

 observed it attacked by Stylops.

 the pubescence on the thorax inclining to griseous ; the abdomen

This may possibly be the Apis atra of Scopoli ; but his description 

 is too brief for determination. 



This species appears during June and July ; it is rather local, but 

 widely distributed. The usual months of its appearance are given ; 

 but it has been taken in August and September. It is frequently 

 found on thistles, usually preferring the flowers of that plant. It 

 has been taken at Southend, Darent Wood, and Shirley Common, 

 also at Sidmouth, South Devon, and at Xorwich.
