A NEW EUEOPEAN SPECIES OF TORTRICIDjE. 

 BY E. MEYRICK, B.A., F.R.S. 



The specimens described below were taken during mj visit to 

 Saas-Fee, Switzerland, in 1900, which produced two new Pterophorida? 

 already described in this Magazine. Though belonging to an obscure 

 group, they constitute a fine and distinct species, and, aided by Mr. J. 

 H. Durrant, I have recently searched the Walsingham collection, in- 

 cluding the extensive series of the group obtained from Zeller and 

 Hofmann, without finding anything like it. In explanation of the 

 generic reference I may add that I now separate Cnephasia from Tortrix 

 on the following characters, viz., veins 6 and 7 of hind-wings normally 

 connate or stalked, thorax usually with more or less marked crest, fore- 

 wings sometimes with raised scales ; in Tortrix as restricted (Eulia 

 and Argyrotoxa being also maintained as distinct) none of these cha- 

 racters occur. 



CnEPHASIA RASTRATA, 71. sp, 

 ^ ? . 26 — 31 mm. Head and palpi fuscous, irrorated with white, palpi 2^. 

 Antennae fuscous, ciliations in <? A. Thorax white, more or less sprinkled with 

 fuscoiis or dark f uscoiis, Avith moderate posterior crest. Abdomen pale whitish- 

 fuscous. Pore-wings elong-ate, posteriorly moderately dilated, costa gently 

 arched, apex obtuse, termen somewliat rounded, rather strongly oblique ; 7 to 

 apex ; fuscous, suilusedly irrorated with whitish, with scattered black scales, 

 sometunes forming distinct lines on veins, and short costal and dorsal strigidse ; 

 basal patch siiffused with brownish towards costa, outer edge formed by a nar- 

 row brownish fascia mixed with black reaching from costa two-thirds across 

 wing, acutely angulated in middle of disc, its angle produced posteriorly into 

 a more or less developed oblong projection ; central fascia narrow, brownish, 

 irregularly sprinkled with black, running from two-fifths of costa two-thirds 

 across wing, acutely angvilated in middle of disc ; costal patch fuscous, flattened- 

 triangnilar, or more usually resolved into a cloudy elongate subcostal streak 

 connected with costa by three small spots or bars ; towards termen about eight 

 scattered strigvilte of black irroration suffused with brown : cilia light brownish 

 sprinkled with whitish. Hind- wings with veins 6 and 7 connate or short-stalked ; 

 pale grey, faintly darker-strigulated. whitish towards base and anterior two- 

 thirds of costa ; cilia whitish, with faint grey siib-basal line. 



Hab. : Saas-Fee, 6000-7000 feet, in August. 



Seven specimens, from rough vegetation growing amongst rocks ; 

 the species was common, occm-ring in company with a large and very 

 white form of C. bellana, which it equals in size, though conspicuously 

 different in colour and markings. The large size will separate C. ras- 

 trata from any other species of the allied- group, but it is also well 

 characterized by the peculiar form of the markings and the termen of 

 fore- wings more oblique than usual.
