TORTRICINA. 207 



ocelloid patch is large, distinct and grey, with enclosed longitudinal 

 black lines. On the costa, before the central fascia, are three gemi- 

 nations, which are produced into strigae to the dorsal margin ; be- 

 yond, are two others, also produced, and reaching to the ocelloid 

 patch. Apical scales black, with grey bases. Cilia plumbeous. 

 Posterior wings umbreous, paler at the base. Marginal scales um- 

 breous, with their bases slightly paler. Cilia white. Legs grey. 

 Abdomen smoky umbreous. 



Very rare ; a single specimen only is known as being captured 

 in Britain, which is in the cabinet of Mr. Edwin Shepherd. It 

 was taken at Whittlesea Mere, about eight years ago, in July, by 

 Mr. Bouchard. 



4. compositella, Fabr. Alis anticis fuscisve brunneis obscuris ; 

 macula dorsali quadrata tristrigata alba ; punctis costalibus qua- 

 tuor geminatis argenteis ; posticis maris basi margaritaceis, apice 

 fuscis ; fcem. fuscis obscuris. 3 Exp. al. 4 lin. 



Head olive drab. Face silvery white. Eyes smoky black. Palpi 

 as long as the head, dirty white. Antennae brown. Thorax glossy, 

 olive-brown, or ashy grey. Patagia same colour as the thorax. 

 Anterior wings glossy ashy-grey at the base, merging into rich 

 golden umber at the apex. At the middle of the dorsal margin is 

 a large curved, somewhat quadrate, silvery-white blotch, with three 

 brown streaks running through it ; the centre one broadest and most 

 denned. On the costa are four sharply- denned, oblique, geminated 

 silvery- white streaks (in some lights cream- colour) ; one before the 

 middle, which is longest and most oblique ; the other three beyond. 

 The apical spot is large and distinct. The second geminated streak 

 unites, and is produced into a lustrous blue line ; lustrous blue scales 

 are also near the apices of the other geminated streaks. The position 

 of the ocelloid patch is marked with a broadish curved streak of pale- 

 violet scales. In certain lights the whole surface of the wing has a 

 faint violet gloss. Apical scales deep umber. Cilia with a lustrous 

 blue gloss, brown at the anal angle, interrupted below the apical 

 spot by a faint streak running through them. Posterior wings silvery 

 white at the base, softening into pale umber, with a lustrous blue 

 tinge at the apex. Marginal scales brown. Cilia pale grey, glossy. 

 Abdomen smoky black, edges of the segments with shining silvery 

 scales. $ Exp. al. 4 lin. Posterior wings wholly fuscous, the 

 bases slightly paler. 



This beautiful species is tolerably abundant; its dimensions 

 are about the same as those of E. nitidana, and it is constant in its 

 colouring. Distinguished from its congeners by the triple streak 

 in the ample clearly- denned dorsal blotch. One variety occurs 

 (the Tortrix dorsanaof Fab. Haw.), which has but one streak in 

 the dorsal blotch (see ' Wood's Ind. Ent/ pi. 31. fig. 933).
