290 TORTRICINA. 



course, diminishing in width, and attains the dorsal margin before the 

 middle. At the subapical portion of the costa is a large, somewhat 

 trigonate patch, and a smaller one at the apex ; and opposite the 

 former, within the anal angle, is another patch, sharply denned, but 

 of irregular shape ; the apical region more or less suffused with 

 chocolate-colour, particularly on the venation, mixed with silvery 

 freckles. On the costa are four rather indistinct geminations, two 

 before and two beyond the central fascia, all more or less produced 

 into silvery streaks, which run along the borders of the principal 

 markings. The dorsal margin is finely maculated throughout, and 

 the pale portions of the wings slightly suffused with chocolate - 

 colour. Apical scales ferruginous, with pinkish-drab bases. Cilia 

 pale ferruginous, with a rosy hue. Posterior wings grey, with a 

 violet tinge ; slightly darker towards the margins, where they are 

 edged with a dark line, the speckling of the under-surface showing 

 through, imparting a mottled appearance above. Marginal scales 

 dark violet-grey, with the bases pale drab. Cilia drab. Abdomen 

 iron-grey, with pale shining scales at the edges of the segments ; the 

 apex grey. Exp. al. 11-11^- lin. 



A rather uncommon species ; closely allied to the succeeding, 

 A, sub- .Baumanniana, and until now confounded with it. It is 

 distinguished by its much greater size, the deeper colours of the 

 anterior wings, the central fascia is more oblique, and reaches the 

 dorsal margin nearer the base than in the latter species. 



The imago appears in May and June among Rushes in 

 damp places. It occurs at Darenth Wood, in the New Forest, 

 in Suffolk, at various places round London, in Cheshire and the 

 north of England; also in Scotland, and at Belfast in Ireland.

Head ochreous. Face slightly darker. Eyes black. Palpi longer 

 than the head. Antennae shining, ochreous at the base above, the 

 remainder brown. Thorax and crest ochreous, sometimes irrorated 

 with grey. Patagia of same colour as the thorax. Anterior wings 

 pale ochreous, with pale -ferruginous markings with lustrous silvery 

 borders. At the base is a patch, sharply defined on the costa, 

 and softening into the ground-colour of the wing ; sometimes it is 

 suffused to the dorsal margin. A broad distinct fascia commences 

 at the middle of the costa, widely interrupted before the centre, 

 from whence it diminishes, and attains the dorsal margin. In the 

 subapical portion of the costa is a large quadrate patch, succeeded by 

 a smaller mark at the apex, and in the anal angle is a third one. On 

 the costa are four indistinct geminations, two before and two beyond
