TORTRICES TAKEN NEAR CAMBRIDGE. 
By WicitamM FARREN. 
Tue following is a list of the Tortrices which my son and I 
captured during 1885 around Cambridge and in Wicken Fen. I 
am afraid it is very scant, especially in specimens; but the reason 
is, I think, the same as referred to (Kntom. 78) in the list of the 
Tinea,—the prevailing strong and cold east winds, which lasted 
nearly all summer. 
Tortrix podana, flying at dusk in the fen, and beaten from mixed 
hedges; one quite a pigmy. ZT’. rosana, abundant in hedges. 7’. dwmetana, 
a fine series flying at sundown; looks like a Tortrix of half the size, and 
very light, owing to its pale under wings, which show plainly in the dim 
twilight; comes to light directly the lamps are lit; has a peculiar zigzag 
movement as it runs up the side of the net; solitary specimens were bred 
from buckthorn, the low creeping bramble of the fen, and yellow loosestrife ; 
is confined strictly to Wicken Fen. 7’. heparana and T. ribeana, commonly 
bred and beaten out, both in the fen and elsewhere. TT’. unifasciana, 
common in privet hedges. T’. costana, bred from various fen plants, and 
abundant at light; some very dark vars. T'’. palleana,* a few only, flying 
with 7’. viridana, which is also rare in the fen; at four o'clock in the 
morning, near a scrubby little oak, about three feet high, in the middle of 
the fen. 7’. forsterana, two only in the fen. 
Peronea variegana, common in whitethorn hedges, in fine variety. 
P. hastiana ; there are two great broods of this in June and October, but 
they keep coming in the intermediate months; some sallow bushes are 
specially infested with this species, nearly every leaf being attacked; I 
have this in great variety, which I must get some old friend to name for 
me. P. shepherdana, bred in plenty from meadow-sweet heads ; seldom 
seen on the wing, but comes freely to light. 
Rhacodia caudana, beaten from sallows, but not common. 
Teras contaminana, beaten in plenty from whitethorn, and in great 
variety; some brightly coloured and strongly marked, others dull leaden 
grey, with scarcely any markings. 
Dietyopteryx lorquiniana (uliginosana, of my young days, when it was 
extremely rare); now bred in abundance from the flower-heads of Lythrum 
salicaria in October, and from shoots of the same plant found in June, but 
is scarce then and hard to find ; this summer brood has the black spot on 
the fore wings, and used to be called the female, but both sexes have the 
* Probably the yellow variety of viridana, known as suttneriana, Schiff., and not 
palleana, Hb. (= icterana, Frol.).—R. 8.
