TORTRICIXA. 33 



produced along the dorsal margin. The central fascia is made up of 

 the same colours, but somewhat darker, much angulated on both sides, 

 and edged here and there with cream-colour. The space between 

 this fascia and the basal patch is streaked and reddish on the costa, 

 then of obscure colour to the dorsal margin, superposed with lustrous 

 blue. Close to the posterior edge of the central fascia, and follow- 

 ing its outline from near the costa to the dorsal margin, is a pale 

 dusky cloud, beyond which, in the middle, is a dark brown spot ; 

 below, there are several others, in a cluster, more or less developed. 

 Near the middle of the apical margin are two or three (sometimes 

 only one) black spots, or longitudinal streaks. The costa is marked 

 throughout alternately with coarse and fine streaks of brown; a brown 

 cloud occupies the apex, sometimes streaky, at others confluent, and 

 extending more or less along the margin. A few lustrous blue 

 scales are towards the apex, and a patch of pale lustrous scales near 

 the anal angle. Marginal scales brown. Cilia slightly shining (long 

 towards the anal angle), dark brown, with ochreous bases, both 

 becoming cream-colour at the anal angle. Posterior wings deep 

 fuscous, darkest at the margins. Marginal scales deep fuscous, with 

 pale ochreous bases. Cilia deep straw-colour, with a dusky line in 

 the middle. Abdomen shining, deep fuscous, the caudal tuft paler.

This species is rarely captured in the imago state, although 

 the larva is to be met with commonly in Teazel-heads. It 

 varies in the intensity of its colours, and also in size. It re- 

 sembles A. Sauciana, but is not so darkly coloured, and is easily 

 separated from it by the ground-colour being more ochreous, and 

 by the posterior margin of the basal cloud being more suffused. 



The imago appears in July at Charlton and Sydenham in 

 Kent, at Southend, near Dover, and throughout the metropolitan 

 district. It is not recorded as having appeared in Scotland or 

 in Ireland. 



The pupa state is assumed towards the end of May. The 

 pupa is about 3J lines long, shining, and of an olive-brown 

 colour. 



The larva is dirty yellowish white, with a shining black head, 

 sometimes piceous ; shield black (sometimes smoky black, with 

 the edges darkest), slightly paler in front, and divided by a 

 slender dorsal line ; the spots are oval, elevated, and of a pale 

 olive-green colour. On the twelfth segment is a transverse, 

 long, elevated mark of olive- green colour, darker than the 

 segmental spots, and with a deep fovea on each side. Anal seg- 

 ments suddenly attenuated, with its apex rugose and shining. 

 It is found commonly in Teazel-heads, of which it feeds in the 

 pith. Before going into pupa it spins a long loose white silken 

 web in the Teazel-head.
