may be expected to be met with all down the Valley of the 
Thames, wherever willows occur.. 
D. semifasciana, Haw.—Widely distributed among sallows, but 
not abundant. The larvee feed in united shoots of sallow in May 
and June, generally preferring dwarf and stunted bushes, and the 
imago appears in July. It does not fly freely till nearly dark, 
when it can be easily taken by the aid of a lantern, flying from 
shoot to shoot, or at rest on the leaves. It also comes to 
sugar. 
Penthina corticana, Hub., picana, Fro.—Widely distributed. 
The larve may be found in May and the early part of June, 
feeding on birch (Betula alba) and on some of the sallows. The 
imago appears in June and July, and should be looked for at 
dusk, flying round the trees, or it may readily be disturbed by 
beating. It may be distinguished from the following species by 
its having large patches of white in the basal portion of the fore 
wings, which sometimes are united and occupy the whole of the 
basal portion of the wings, separated by a broad, irregular band 
of black from the white apical patch. This extreme form is, 
however, of great rarity. 
P. betuletana, Haw.—Much commoner than the preceding 
Species, which it much resembles in general appearance. 
L. capreana, Hub.—Local, but distributed. This species 
may be reared from collected shoots of sallow in May and 
June, which should be kept in a flower-pot, in a cool and 
airy place. The imago appears in July, and may be obtained 
by netting at dusk, and also by beating. It is more common 
among sallows in hedgerows, and this season (1879) was unusually 
abundant. It is recorded from West Wickham and Croydon in 
Surrey ; Haslemere, Tilgate, Lewes, and Hastings, in Sussex ; 
and in Kent at Darenth, Strood, and Tunbridge Wells. 
P.sororculana, Zett,=prelongana, Gu.—Distributed through- 
out, but not common in the South of England. I have found this 
species scarcer in these counties than the preceding one. The 
larva is said to feed in the autumn on birch; the imago is 
certainly to be taken in May, amongst birch trees. 
P. pruniana, Hub.—Common everywhere, and most abundant 
by whitethorn hedges. 
P. ochroleucana, Hub.—Widely distributed, and not uncommon 
among roses, especially the cultivated sorts, in gardens. It is
