TORTRICINA. 83 



3. Demarniana, Eisch. v. R. Alls anticis albis ; fascia basi media 

 apiceque fuscis obscuris ; macula ocellari ad angulum analem ro- 

 tundata alba ; capite albido ; posticis fuscis. tf Exp. al. 7 lin. 



Head and face pale drab. Eyes black. Palpi above and at the sides 

 slightly grey, whitish beneath. Antennae dull brown. Thorax dull 

 brown. Patagia drab, with a dark brown mark on the shoulder. 

 Anterior wings glossy white, with umber markings ; at the base is a 

 streaky patch, extending one-third along the costa and the same 

 distance along the dorsal margin ; its posterior edge is oblique from 

 the costa to the fold, there forming an angle, and attains the dorsal 

 margin in a nearly straight line ; an oblique fascia extends from the 

 costa to the anal angle, with both its edges much angulated. The 

 costa is streaked throughout, and beyond the central fascia are five 

 geminations, all directed to a point below the apical spot, which is 

 distinct, and has a white line below it, running through the apical 

 scales and cilia. Below the costa, from the basal patch to the apex 

 the wing is clouded with dark brown or fuscous. The ocelloid 

 patch is reniform, being impinged upon by a projecting angle of the 

 central fascia, of white colour, with a transverse streak of brown 

 running through, which is more or less marked with longitudinal 

 lines ; the dorsal white blotch streaked with umber. Apical scales 

 umber, with white bases. Cilia shining brown, with white bases, 

 wholly white at the anal angle and iron-grey beyond it. Posterior 

 wings clothed with fuscous scales on a white ground. Marginal 

 scales fuscous, with straw- coloured bases. Cilia shining pale grey, 

 the tips whitish. Abdomen fuscous ; the caudal tuft at the apex 

 drab. $ Exp. al. 6-7 lin. 



This does not appear to be a variable species, and is rather 

 uncommon : it is larger than its congeners, and much resembles 

 the pale forms of Lith. naevana, but the white portions of the 

 anterior wings are much brighter. 



The imago appears in June and July, among Birches, at 

 Darenth, Birch, West Wickham, and other woods ; in Cheshire, 

 &c. 



4. crenana, Hub. Alis anticis nitidis ; costa nigris, dorso albis ; 

 costa strigis geminatis cinereis ; capite ochraceo ; postieis nitidis, 

 fiisco-griseis, apice saturatioribus. tf Exp. al. 6-J 8 lin. 



Head dusky ochreous. Face smoky black. Eyes black. Palpi 

 iron-grey; the apex dull brown. Antenna black. Thorax and 

 patagia smoky black, with two white spots behind on the former. 

 Anterior wings glossy white on the dorsal margin and smoky black 

 on the costa : these colours meet in the middle of the wing, and are 

 bounded by an undulating edge from near the base to the apical 

 margin, arching twice in its course, like Anchylopua biarcuana ; the 

 black colour is most intense at the middle of the wing, the remainder
