218 TORTRICINA. 



The imago appears in July and August, but is seldom taken 

 on the wing. It occurs among young Fir-trees round London, 

 Manchester, and other places. 



The pupa is 5 lines in length ; the head, thorax, and wing- 

 cases, shining chestnut-brown; the abdomen dull, umbreous 

 towards the base, becoming paler at the apex ; the anal ter- 

 mination obtuse. 



The larva is from 6 to 7 lines long, fleshy, sluggish ; of a 

 dirty brown-red colour, with a few short hairs disposed about the 

 body. Head small, black, and shining ; the shield black on the 

 vertex, divided by a pale dorsal line, and at the sides reddish 

 brown. The body without markings, except on the anal segment, 

 which bears a transverse row of darkish spots ; the underside 

 paler ; apical joints of legs black ; pro-legs rudimentary ; the 

 anal pair slightly larger. It feeds in the young shoots of the 

 Scotch Fir, and its presence is detected by the distorted appear- 

 ance the attacked shoots assume. It should be sought for about 

 the end of April. 



2. Pinicolana, Doub. Alis anticis subargenteis ; maculis rubris, 

 costa punctis geminatis productis ; posticis griseis. rf Exp. al. 

 9-10 lin. 



Head and face dull sulphur- colour, with a reddish tinge. Eyes 

 black. Palpi longer than the head, dull sulphur- coloured above and 

 between, red at the sides and beneath. Antenna grey, alternated 

 with brown. Thorax pale madder red, paler behind. Patagia 

 deeper coloured at the base, cream-colour at the apex. Anterior 

 wings madder red, with a pale orange cloud along the dorsal margin, 

 and sometimes with another broad, similar- coloured cloud before the 

 middle. On the costa are usually six silvery marks, of which the 

 two basal ones are produced, and reach the dorsal margin, uniting 

 beyond the middle of their course. The fourth and fifth, and some- 

 times the third, fourth, and fifth, unite beyond the middle of the 

 wing, afterwards forming a broad arch resting on the dorsal margin ; 

 the anterior portion of this arch is sometimes furcated ; the pos- 

 terior part, shortly above the dorsal margin, gives out a bright streak, 

 sometimes interrupted, but usually meeting the apical costal mark. 

 Apical margin sometimes entire, at others wavy ; in the latter case 

 owing to the presence of small silvery maculations. Apical scales 

 with iron-grey tips and silvery bases. Cilia iron-grey, with pale 

 grey bases. Posterior wings clothed with coarse scales, pale grey at 

 the base, and darkening somewhat towards the apex ; the apex and 

 margin with a reddish tinge, especially the former. Marginal scales 

 grey, with whitish bases. Cilia dirty white. Abdomen pale, shining
