apical streak, 5th and 6th clothed with golden brown 

 hairs ; beneath clothed with grey hairs. Legs with pale 

 fulvous hairs ; posterior tarsi, and the apex of the pos- 

 terior tibiae also (in the spring form) clear testaceous ; 

 apical joints of all the tarsi testaceous. Length 9 — 

 11 mm. 



Hah. On sallows in spring, and blackberry flowers in 

 summer. A local species, but occurring at Norwich, 

 Southwold, Chobham, Bournemouth, and in Devonshire. 



This is, I believe, another double-brooded species con- 

 sidered by some authors as constituting two, but the 

 distinguishing characters are so slight and almost ex- 

 clusively those of coloration that I have no hesitation 

 in uniting the forms to which they belong.
