TORTRICINA. 235 



The larva is about 6 lines long, stout, sluggish, and of a 

 dirty white, sometimes pinkish colour, with the head and shield 

 very pale rufous. It feeds in Acorns, and is full-fed at the end 

 of September or beginning of October. When about to assume 

 the pupa state, it eats its way out, just above the cup, and seeks 

 a convenient place, where it spins a cocoon of pale brown colour, 

 of the consistency of paper. According to M. Guenee, the cocoon 

 should be sought for among Moss.

Head dull dark grey, palest behind. Face dull dark grey. Eyes 

 intense purplish brown, with drab scales behind. Palpi as long as 

 the head, grey. Antennae smoky black, paler beneath. Thorax 

 smoky black, streaked transversely, and irrorated with grey. Patagia 

 paler at the apex than the thorax. Anterior wings dull pale grey, 

 with darker markings of fuscous and umber. At the base is a 

 streaked umber rhomboid patch, its apex slightly truncate : it ex- 

 tends one-fourth along the costa, and one-third along the dorsal 

 margin. The costa is umber- coloured, and before the middle are 

 two, and beyond, five, geminated grey streaks : these latter produced, 

 and directed towards a point below the apical spot, which is distinct, 

 umber anteriorly, grey posteriorly. From the middle of the dorsal 

 margin to the apex is a dusky umber cloud, and within it is the 

 ocelloid patch, which is very distinct, but irregular in shape ; it is 

 bounded by brown or black curved lines and streaks of lustrous blue 

 scales ; the space between is scarcely paler than the apical cloud, 

 and is marked with longitudinal black lines, sometimes with spots. 

 At the middle of the dorsal margin is a whitish blotch, streaked with 

 black. Apical scales black (at the anal angle mixed with white), 

 with white tips. Cilia dark brown, shining, speckled and tipped with 

 white, pale at the anal angle. Posterior wings rich purplish brown, 

 sometimes umber, darkest at the apex. Marginal scales shining, of 

 similar colours, the bases pale. Cilia pale grey. Abdomen umber, 

 with the margins of the segments shining grey. $ Exp. al. 7| 8^

This is a common species where Beeches grow. It varies 

 considerably in size and colour. In general aspect it is like 

 C. splendana, but is distinguished from it by the darker rhom- 

 boid-marked basal portion of the anterior wings. 



Obs. In a very oblique direction, in fresh specimens, the 

 upper wings exhibit a pale green iridescence at the apex and 

 base, and pale violet on the costa. The posterior wings are
