224 THE ENTOMOLOGIST. 
add that I have reared it from the pads, in which I find the 
pupa enclosed in a flossy shroud, in considerable abundance, 
both males and females, fully fifty having emerged in the first 
half of August. Each morning, early, I find them in my glass- 
topped boxes, and have learned to recognise the male by its 
merry, restless flight. The female is more staid and sober in 
its life and movements, the oviduct being prominently exserted 
and coloured, just as Mr. Meade, whose diagnosis is appended, 
describes it to be. This present Cecid would seem to frequent, 
perhaps exclusively, the leaves of the white willow (S. alba), 
whereas a cognate species affects the osier willow (S. viminalis). 
This is also figured by Bremi; but in the latter case the margin 
is continuously rolled in, whereas in the former it is only in- 
terruptedly so.
