222 TORTRICINA. 



larger, and further distinguished by the broader fuscous-ochre 

 apex of the wing, which in the latter species approaches copper- 

 colour. 



7. Turionella, Linn. Alis anticis cinereis, strigis strigulisque fuscis 

 ochraceis ; ad apicem late ochraceis ; costa margineque apicali 

 punctis nigris ; posticis basi albis, apice fuscis. $ Exp. al. 

 9-9| lin. 



Head and face pale ferruginous, the latter slightly paler below. 

 Eyes black. Palpi as long as the head, dull drab above and between, 

 inclining to ferruginous at the sides and beneath. Antenna fuscous, 

 with a slight ferruginous tinge towards the base above. Thorax and 

 patagia broadly pale ferruginous in front, behind with deep fuscous 

 scales tipped with pale grey. Anterior wings : dull ochreous brown 

 at the base, merging into pale ferruginous or dull ochreous at the 

 apex, with numerous freckles and minute markings composed of coarse 

 black and white scales, thus imparting to the surface a leaden-grey 

 colour ; the markings are arranged in wavy streaks from the costa 

 to the dorsal margin, and occupy nearly the whole surface to beyond 

 the middle, where there is a faint indication of an oblique, brown 

 fascia, beyond which the apical region, which has a coppery lustre 

 when viewed obliquely, and is only sparingly marked with leaden- 

 grey streaks ; beyond the fascia, the costa is blackish, and marked 

 with four geminated streaks, those nearest the base most produced. 

 Apical scales blackish, with white tips. Cilia fuscous grey, with 

 white tips. Posterior wings whitish at the base, softening into a 

 dark cloud at the apex, composed of fuscous and black scales ; at the 

 margin is a row of small, round, yellow spots, and the dark colour 

 more or less continued to the anal angle. Marginal scales dusky. 

 Cilia very pale grey. Abdomen pale, shining grey, the caudal tuft 

 drab. $ Exp. al. 9^10 lin. In colour brighter, and the grey 

 streaks less suffused than in the $ , thus permitting the ground- 

 colour of the wing to be more visible ; the fascia beyond the middle 

 also more distinct. 



A very rare species in cabinets, and only during the last few 

 years detected in this country. It is of the size of R. Buoliana, 

 some specimens attaining those of large specimens of R. Pinico- 

 lana ; in the intensity of its colour and number of streaks it like- 

 wise varies. It is the largest known British species having a buff 

 tip to the anterior wings. 



The imago appears at the end of May and June, among young 

 Scotch Fir-trees. It has been captured at Birch and West Wick- 

 ham Woods ; at Black Park, and a few other places. 



The larva feeds in the young shoots of the Scotch Fir, causing 

 them to droop and die, in this respect differing from the habit of
