28 TORTRICINA. 



the space between paler, assuming the appearance of two broadish 

 streaks following the angulation of the fascia, and produced to the 

 dorsal margin ; pale at their origin ; then dark grey and brown, 

 speckled with cream -colour, particularly on the fold. The two spots 

 on the edge of the basal cloud, as in A. Cynosbatella, are, in this 

 species, replaced by a rich oval golden-brown one, and scarcely 

 separated from the fascia. The apical portion of the wing is marked 

 with three equidistant oblique marks on the costa (the apical one 

 sometimes produced to the apical margin), with smaller ones be- 

 tween, and succeeded by an eye-like spot at the apex, all of a brown 

 or dusky colour ; in the middle are some golden-brown clouds, 

 streaked with black, and mixed with patches of pale lustrous blue or 

 leaden-coloured scales. Apical margin brown. Apical scales brown, 

 with pale bases. Cilia same colour, but slightly paler and somewhat 

 mottled ; both becoming white at the anal angle. Posterior wings 

 fuscous. Marginal scales shining, fuscous, with luteous bases. Cilia 

 shining, pale straw-colour. Abdomen fuscous. $ Exp. al. 7-8 lin. 



Also a very common insect ; not variable, save as to intensity 

 of colour. Allied to A. Cynosbatella, but much smaller, and 

 further distinguished by the clouded apex of the anterior wings. 

 In this latter character it resembles A. Sauciana ; but the basal 

 cloud of Sauciana extends two-thirds along the costa, whilst in 

 this species it extends only to one-half. The variety pullana, as 

 referred to this insect by J. F. Stephens, and figured in Wood's 

 ' Index Entomologicus/ pi. 30. fig. 891, has the posterior edge of 

 the basal cloud rounded towards the dorsal margin. 



The imago appears from the middle of June to the beginning 

 of July, and is generally distributed throughout the country. It 

 occurs also in Scotland and in Ireland. The north of England 

 and Scotch specimens are smaller and more intensely coloured 

 than those captured in the south of England. 



The larva is full-grown in May, and feeds on the Sloe (Prunus 

 spinosa), Plum, Mountain Ash, Cherry, &c.

Head smoky-brown. Face smoky-brown, approaching to black. 

 Eyes black. Palpi intense brown, paler beneath. Antenna dark 

 brown, slightly paler beneath ; the basal joint clothed with black 

 scales. Thorax black or obscure brown, alternated with pink ; the 

 bifid tuft black. Patagia of same colours as the thorax. Anterior 

 wings dull, pale rose-pink. The dark portion of the wing extends 

 to the middle of the costa and four-fifths along the dorsal margin,
