TORTRICINA. 203 



The pupa is 3^ lines long, and amber-coloured. 



The larva is dirty white, from 4 to 4^ lines long; the head 

 hazel, with the sutures chestnut-colour ; the shield luteous, 

 very transparent, the base clouded with hazel, and divided by a 

 pale dorsal line ; the spots are oval, pale smoky-black, edged with 

 opaque white, slightly raised and shining ; the anal segment has 

 a large pale smoky-black oval patch on the vertex. It makes a 

 cocoon lined with white silk, covered externally with the gnaw- 

 ings of bark, under the loose pieces of which it may be found in 

 the autumn and winter. It does not go into pupa until April, 

 or the beginning of May. 



3. argyrana, Hub. Alis anticis cinereis, nebulis strigis fusco brun- 

 neoque variis ; macula oblonga medio marginis dorsalis fusco - 

 strigata; posticis maris basi pallidis, marginibus atris; fcem. 

 fascia, basi dilutioribus. c? Exp. al. 4-6 lin. 

 Head drab and black, paler behind. Face drab. Eyes black. 

 Palpi drab, mixed with black, paler beneath. AntennaB shining, 

 dusky drab. Thorax and patagia umber, mixed with drab ; the 

 latter paler, especially at the apex. Anterior wings dull, variegated 

 with umber, ochreous, and white, with a large white blotch upon the 

 dorsal margin. At the base is a rhomboid patch, streaked with 

 dark-umber transverse lines, its posterior edge darkest, and sharply 

 angulated on the dorsal margin. At the middle of the costa is a 

 broad oblique umber streak, suffusing with the basal patch and the 

 pale-umber colouring of the apical portion of the wing. Before the 

 middle of the costa are two, and beyond four, white geminated streaks ; 

 the interspaces umber. The first and third of the apical streaks are 

 produced into silvery undulating lines to the anal angle, which, in 

 their nether portion, with the yellow mark between, spotted with 

 black, form the ocelloid patch ; this yellow mark is continued to the 

 costa, and above the ocelloid patch is crossed by an elongated umber 

 cloud. The apical spot distinct, and with the margin marked with 

 black and yellow scales ; below the spot is a white mark ; a white 

 streak runs up from a similar- coloured patch at the anal angle. 

 The dorsal blotch is quadrate in form, and streaked with wavy black 

 lines. Apical scales black, with the tips yellow. Cilia dusky grey, 

 or pale brown, somewhat mottled, both becoming white at the anal 

 angle. Posterior wings smoky black, with a broad pale patch 

 within, which is white at the base, its outer extremity merging into 

 pale fuscous. Marginal scales smoky black, with yellowish bases. 

 Cilia white. Abdomen umbreous. <j> Exp. al. 5-6^ lin. Posterior 

 wings fuscous, palest at the base ; marginal scales fuscous ; cilia pale 

 grey.
