214 TORTRICINA. 



Palpi longer than the head, smoky black above and at the sides, 

 paler beneath. Antennae black. Thorax and patagia shining, olive - 

 brown, the latter rather paler. Anterior wings shining, brown, with 

 a golden lustre, and marked with silvery streaks. The basal portion 

 olive-brown, the remainder thickly irrorated with ochreous or orange- 

 coloured scales. Before the middle of the costa are two bright silvery 

 streaks, which are produced across the wing, angulated, and some- 

 what diverging, before attaining the dorsal margin. At the middle 

 and beyond, the costa is black, and marked with six or seven silvery 

 streaks, white at their origin, and more or less produced across the 

 disk, where they assume a pale bluish colour ; the innermost, central, 

 and subapical of these streaks are those which are usually produced, 

 sometimes continuously, at others interruptedly, towards the anal 

 angle. At the middle there is sometimes a slight indication of a 

 dark central fascia. Apical scales black, twice interrupted by 

 ochreous patches ; one below the apex, the other before the anal 

 angle. Cilia shining, iron-grey, in some aspects with a violet tinge. 

 Posterior wings and marginal scales rich purplish brown, the latter 

 with paler bases. Cilia white. Abdomen dark brown, the caudal 

 tuft dull drab. $ Exp. al. 6-6| lin. 



A common species ; varies in size, but tolerably constant in 

 colour. It is allied to A. cosmophorana, but distinguished from 

 it by having the central streaks uninterrupted, and less brilliant. 

 It still more closely resembles A. splendidulana, but is larger, its 

 general colour paler, and the lustrous markings not so wide and 

 diffused. 



The imago appears in May, flying about Spruce Firs near 

 Croydon, West Wickham, and other places in the Metropolitan 

 district. 



The pupa is 3 lines long, and shining. This state lasts about 

 three weeks. The puparium is pale amber-colour. 



The larva when full-grown is about 5 lines long, of pale 

 yellow- colour, and slightly shining. The head pale hazel-brown, 

 with the sutural marks black ; the shield very transparent and 

 horny, with two pale spots on the posterior margin ; anal segment 

 same colour as the head ; spiracles brown. It apparently feeds 

 on the seeds of the Fir-cones, living through the winter, and 

 assumes the pupa state in April, in the central or woody portion. 

 Mr. Edwin Shepherd appears the first to have observed the 

 larva in this country, and he gives an interesting account of the 

 insect in the ' Zoologist ' for 1850, p. 2748.
