THE TORTRICES OF SURREY, KENT, AND SUSSEX. 131 
P. corticana, W. V.—Abundant everywhere among oaks in July 
and August. The imago varies from drab to black, including 
green, olive, and fuscous forms. ‘lhe larva feeds on the oak. 
P. profundana, W. V.—Distributed throughout among oaks, 
but not so common as the preceding species. The imago appears 
in July and August, and is very variable. The larva is to be met 
with in May and June. 
P. opthalmicana, Hiib.—An uncommon species; the imago 
appearing in August and September among poplars and aspens. 
It has occurred in each of these counties, but the localities are 
limited: Strood, Folkestone; Lewes; Croydon and Wimbledon. 
P. occultana, Doug.---Local and rare in these counties. It has 
occurred at Birch Wood; Brighton; and near Weybridge. The 
imago appears in June and July, and is to be met with among 
larch and fir trees. 
P. solandriana, Linn.—Common throughout. The imago 
appears in July and August, and may readily be obtained by 
beating. The larva feeds on birch, hazel, and I have found it 
commonly on Cornus sanguinea. It is a variable species, but yet 
constant in its variations. 
P. semifuscana, Haw.— Widely distributed throughout among 
sallows; the imago appearing from July to October, and may be 
taken on the wing at dusk, and also at light. The larva feeds on 
the sallow in June. This species may be distinguished from 
P. solandriana and P. sordidana by its more shining appearance, 
and the silvery whitish colour of its hind wings. 
P. sordidana, Hub., = stabilana, Steph.— Distributed, but 
local. ‘The imago is of a dull brown colour, and more constant 
than either of the preceding species. It appears in September 
and October, and is not uncommon among alders, upon which the 
larva feeds. 
Ephippiphora bimaculana, Don.—Distributed and not un- 
common among birches, especially in heathy places. The imago 
appears from July to September. ‘The larva is to be found in the 
shoots in the spring. 
E. cirsiana, Zell.— Not uncommon among thistles in marshy 
places, and generally distributed. The imago appears in June and 
July, and may be captured on the wing at dusk, but it is not a free 
flyer. The larva feeds in the stems of thistles (Carduus palustris), 
and also of Centaurea nigra, in the autumn and following spring.
