To speak first of the novelties j these aro three : 
I. Opiiiodes lunaris, a single specimen taken at light in 
Stratton Sh-awless Wood, by myself, .Afay 20th. This specFes has 
Its home in Hungary and Dalmatia, and occurs in dry oak 
■woods throughout Southern and Central Europe ; it is, however, 
very uncertain in its appearance, being comparatively common 
in some seasons while it is wliolly absent in others. In this 
country it has occurred once in Hampshire, once in Kent, and 
twice in Sussex, the last recorded instance being at Brighton, 
in 1875. 
If. Dictyoptery.x (1) LaRQUiNiANA. Fivo specimens taken at 
liglit at luinwortli by Mr. A\ . H. B. Fletclicr and myself, end 
of July. This species is tolerably plentiful at Wicken Fen 
(Cambridgeshire), and formerly occurred at Whittlcsea Alerc; 
till lately, however, very little was known of its liabits, and it 
was esteemed an extreme rarity. On the Continent it is recorded 
from the North of Franco and from Braudonburf 
It IS now found to bo double-brooded : the first brood appearing 
about the middle or end of J une, and having invariably, as far 
as I know, a conspicuous black spot in the middle of the front 
wings; this brood is the one known to authors. There is, however, 
another appoiiring in September and hibernating, which appears 
to bo more numerous. It is as a rule larger than the summer 
brood and without the black spot, in place of which, however, it 
IS liable to a longitudinal streak of dark brown or black extending 
the entire length of the wing. Taking into consideration the 
economy of this species and its tendency to a striped form, I 
think it should certainly bo referred to the genus Peronea rather 
than Didyopteryx. 
The larva producing the first brood feeds in May on the 
loaf- buds of the Purple Loosestrife (Lythrnm salicariaj ; that of 
the second brood feeds in August on ihQjloicers of the same plant 
probably the more congenial food may account for the greater 
luxuriance of this brood. 
1 ho capture of this species at Ran worth is of peculiar interest, 
as it is one of the special insects of the old Huntingdonshire 
* Thi.s larva has not as yet been described ; but as I have sent specimens 
to Mr. Barrett for that piu^)ose, I will not describe it now.
