TORTRICINA. 157 



Formerly incorporated in the genus Argyroloza by the late J.F. 

 Stephens, but widely separated from it in the Museum Catalogue 

 under the above name. The insects comprised in these genera, 

 however, possess several characters in common : their points of 

 difference are, that the anterior wings are longer, and the apical 

 margin rounded in Hemerosia, whilst in Argyrotoza, the latter 

 is obliquely truncate. The middle joint of the palpi in Argyro- 

 toza is considerably shorter in relation to the apical than in this 

 genus (Hemerosia).

 bris ; posticis subnitidis nigro-fuliginosis. c? Exp. al. 4J lin. 



Head and face smoky brown. Eyes black. Palpi longer than the 

 head, dull smoky brown, slightly glossy beneath. Antennae glossy, 

 smoky black. Thorax and patagia dull dark brown, with a purplish 

 tinge ; anterior wings glossy, smoky umber, with a purplish shade, 

 softening into rich orange or brick-red at the apex ; on the apical 

 portion of the costa are two or three faintly-defined streaks, of a 

 slightly paler hue ; apical scales dull red. Cilia glossy, iron-grey 

 at the apex, slightly fulvous along the margin, becoming again iron- 

 grey beyond the anal angle. Posterior wings variable, sometimes 

 chocolate brown, at others golden brown, with a darker softened 

 cloud near the anal angle. Marginal scales brown. Cilia straw- 

 colour, glossy. Abdomen dark umber. $ Exp. al. 5 lin. 



Not a common species, constant in size and colour. 



The imago appears in May and June. It occurs at Coombe, 

 Birch, Greenhithe, and Darenth Woods ; at Riddlesdown, Lewis- 

 ham, and near Ripley ; in Devonshire, Cheshire, at Meonstoke, 

 and in the New Forest. It likewise occurs in the vicinity of 

 Edinburgh, and at Holywood, Co. Down, in Ireland. 



The larva feeds on the leaves of the Apple and Service tree, 

 and we are credibly informed that it burrows into the bark to 

 undergo its final change. 



FAMILY IV. PERONEID.BB. 



The insects comprised in this group are characterized by the 

 presence of tufts of elevated scales on the anterior wings (Chei- 

 matophila excepted), by having the costa slightly incised or emar- 

 ginate in the middle (in Teras considerably so), and being always 

 obtusely dilated towards the base, where, as well as towards the 

 apex, it is roughly clothed with scales, but never marked with
