grey, with a conspicuous scaleless fenestrum below the base of the 

 cubitus, reaching nearly to the origin of vein 2 ; cilia brownish 

 grey. A bdomen brownish grey ; anal tuft paler. Legs pale 

 brownish cinereous.

A single $ , given to me by Mr. White, is in extremely poor 

 condition ; I should certainly not have described it had it not 

 been for the peculiar character of the fenestrum in the hindwing. 

 It was taken from a series in his collection, which included more 

 than one species. I certainly recognised Crocidosema plebeiana 

 Z. among them, and there were others similar to the one here 

 described.

Unnamed specimens in Mr. White's collection ; not in good 

 enough condition for identification. I did not meet with the genus 

 Eucosma in Tenerife.

 (Plate LIII. fig. 2.) 



Antennae brownish cinereous. Palpi varying from ochraceous 

 to brownish fuscous. Head and Thorax brownish fuscous above ; 

 the tegulae paler, sometimes ochraceous. Forewings with the 

 costa evenly arched, termen slightly sinuate ; ochraceous, more 

 or less suffused with brownish, or dark fuscous scaling, the 

 markings indicated by black patches ; in an ordinary variety 

 the wing is much mottled and traversed by sinuous streaks, the 

 costa being streaked and spotted throughout; a strong dorsal 

 patch is indicated, coming from the base below the fold, angulated 

 above the fold at one-third, and produced along the more or less 

 spotted dorsum to an obliquely erect antetornal patch of the same 

 colour, terminating a little below half the width of the wing ; in 

 some varieties a curved band of similar blackish patches descends 

 from the middle of the costa, bending outward through the end 

 of the cell, and attenuated to the apex, but this is sometimes quite 

 obsolete ; a narrow blackish line, broken into spots above the 

 tornus, follows the termen before the ochraceous cilia, which are 

 mottled with brown and blackish above the middle and at the 

 apex, but always with a pale line along their base; in some 

 varieties the upper edge of the dorsal patch and the lower half of
