THE TORTRICES OF SURREY, KENT, AND SUSSEX. 269 
C. cana, Haw., = Scopoliana, Wilk.—Distributed throughout. 
The imago appears iu June and July, and is not uncommon 
among thistles, particularly in dry situations. It flies freely at 
dusk, and is also to be seen during the day at rest upon the 
leaves. 
G. Scopoliana, Haw., = Hohenwarthiana, Gn., Wilk.—Not- 
withstanding that the doubts attending the nomenclature of this 
and the two preceding species have been cleared up by Mr. C. G. 
Barrett (EK. M. M., vol. x., pp. 4—6), some confusion still exists 
owing to the fact that Scopoliana, Wilk., is now known as Cana ; 
and Hohenwarthiana, Wilk., becomes Scopoliana. Common 
throughout these counties. ‘The imago appears in June and July 
among black knapweed (Centawrea nigra), in the seed-heads of 
which plant the larva feeds. 
C. cecimaculana, Hub.—Distributed throughout; nowhere 
common. The imago appears in July among mixed herbage, and 
chiefly upon the chalk. It has occurred at Croydon, Caterham, 
Box Hill; Darenth, Folkestone; Brighton and Lewes. 
C. decolorana, Frr.-— Local. Mr. Machin records having 
reared this species in some numbers from larve feeding in the 
seed-heads of golden-rod (Solidago virgaurea), collected at the end 
of September and in October, in woods in Kent and Surrey. The 
imago appears in June and July among golden-rod, and is to be 
met with on the wing at dusk. Hitherto confounded with the 
following species. 
C. emulana, Schl., = modestana, H.-S., = tripoliana, Barrett. 
—The reasons for altering the nomenclature of this species to 
C. tripoliana will be found in Mr. C. G. Barrett's notes on 
Tortrices (EK. M. M., vol. xvii., p. 84). The imago appears not 
uncommonly along the bank of the Thames among Aster 
tripolium in July, and flies freely at dusk. ‘The larva feeds in 
the seed-heads of the same plant, and is full-fed towards the end 
of September or early in October. 
C. expallidana, Haw.—Local and rare. The imago appears 
in June and July, and is to be found on chalk downs and grassy 
banks. It has occurred at Folkestone, Dover; and Caterham. 
C. citrana, Hub.—Local and rare. The imago appears in 
July, and has occurred at Folkestone and Hastings. ‘The larva 
is said to feed in the flowers of Artemisia campestris. 
T'rycheris mediana, W. V.—Local. The imago appears in
