TORTRICINA. 77 



2. cinerana, Haw. Alls anticis albidis ; basi macula rhombea nigra ; 

 lineis obliquis cinereis ad costam praecipue ; apice puncto nigro ; 

 postieis fuscis, apice saturatioribus. rf Exp. al. 6-7^ lin. 



Head hoary grey behind, with a pale tawny tinge in front, and 

 mixed with dusky scales behind the antennae. Face pale, tawny 

 above, grey below. Eyes black. Palpi dusky grey, paler beneath 

 and between. Antennae dusky grey ; basal joint clothed above with 

 pale grey scales. Thorax iron-grey in front ; the vertex pale grey 

 or drab, irrorated behind with iron-grey and drab scales. Patagia 

 iron-grey at base, drab at the apex. Anterior wings dirty white or 

 very pale drab, streaked and marked with umber scales having drab 

 tips, giving the insect a hoary grey appearance ; at the base is a 

 rhomboid mark, more or less intense, streaky, and having its outer 

 edge darkest ; the costa is streaked throughout with oblique lines, 

 those on the apical half alternately broad and narrow, the broad ones 

 being produced, some of them uniting into a streak running down 

 the apical margin ; the apical spot distinct. In the centre of the 

 wing is an oblong patch, and above it a number of longitudinal 

 streaks ; the dorsal margin faintly streaked transversely. The ocel- 

 loid patch is indicated at the anal angle by two pale lustrous leaden- 

 coloured streaks, divided broadly by an umber cloud, bearing the 

 usual longitudinal black lines. Apical scales alternated broadly 

 with drab and umber, with pale bases and greyish tips. Cilia alter- 

 nated in same way, but paler, and both becoming whitish at, and 

 darker again beyond, the anal angle. Posterior wings clothed with 

 coarse pale fuscous scales, on a pale grey ground, becoming darker at 

 the apex. Marginal scales pale fuscous, with still paler bases. Cilia 

 whitish, with a pale fuscous tinge. Abdomen and caudal tuft pale 

 fuscous, the latter dull. Exp. al. 6-8 lin. 



This is a common insect in some places, and does not vary : it 

 is very like the grey specimens of L. nisella, but always wants 

 the coloured blotch on the dorsal margin ; it is also larger in size. 

 Wood's figure (Ind. Ent. pi. 32. fig. 946) is a good representa- 

 tion of this insect. This species, when viewed very obliquely, 

 nearly in a plane level with the surface of the wings, shows 

 a beautiful iridescence of a delicate violet colour. By some per- 

 sons this insect is thought to be only a variety of the preceding ; 

 but Mr. Foxcroft, whilst collecting at Rannock, took hundreds 

 of L. cinerana, and not a specimen among them which could be 

 referred to L. nisella, or to any of its varieties. 



The imago appears in July and August, amongst Poplars and 

 Aspens, in the metropolitan district, in the west of England, 

 and in Scotland.
