a Genus of Tineida. 121 



Posterior wings shining grey, with yellowish grey cilia. 



In var. b, the anterior wings are very much paler than in the 

 typical form of the insect, the ground colour being ochreous. 



This species is by no means rare, but is generally only taken 

 singly ; it is widely distributed, occurring in most parts of 

 Europe. Zeller thinks that it is double-brooded, but I do not 

 feel confident on this point ; the larva feeds on sallow, and curls 

 up the end of the leaf so as to form a cone, of which it eats the 

 inner cuticle ; these cones are in September and October by no 

 means scarce, and I have several times found the larvae in them 

 (more frequently they are empty). The perfect insect appears at 

 the end of autumn, and hybernating is again to be met with in 

 spring, when of course it is rather the worse for wear. 



Sp. 4. Stramineella, n. sp. (PI. XIV. fig. 9.) 

 Alis anticis stramineis, rufo-brunneo irroratis, triangulo costali 

 rufo-brunneo marginato, non dilutiore. 



Sulphurella, Wood, Ind. Ent. pi. 51, f. 1623 (non Haw. St.) 



In the colour of the anterior wings this comes nearer to 

 Coriscium sulphurellum than any other allied species ; but its straw 

 yellow, and not sulphur or lemon colour, and the dark margin of 

 a costal triangle, sufficiently distinguish it, independently of the 

 generic difference. 



Expansion of the wings G£ lines. 



Head and face pale straw yellow ; palpi the same, the terminal 

 joint externally rufous brown before the apex ; antennae pale 

 yellow, with dark brown annulations ; thorax straw colour ; abdo- 

 men grey brown, beneath whitish ; the four anterior legs have the 

 femora and tibiae dark rufous brown, tarsi yellowish, with the ends 

 of the joints darker : the posterior legs have the tibiae dirty 

 whitish yellow at the base, and pale reddish brown at the apex, 

 tarsi dirty yellowish, the ends of the joints darker. 



Anterior wings pale straw colour, with numerous red brown 

 scattered spots, of which the two most conspicuous form the 

 margins of the usual costal triangle, which is concolorous with the 

 rest of the wing ; towards the apex the wing is suffused with 

 reddish ; apical cilia straw colour, mixed with reddish, inner mar- 

 ginal cilia grey. 



Posterior wings shining grey, with grey cilia. 



Of this species, which is totally unknown on the continent, I 

 have two specimens, which were taken in Torwood, Stirlingshire, 

 in September. Mr. Stephens has the specimen that was figured 

 by Wood.
