154 TORTRICINA. 



tion. Before and beyond the middle of the costa proceed two slender 

 curved fasciae, which attain the dorsal margin, suffusing in their 

 course; viewed obliquely, the darker markings are found to be 

 possessed of a pale violet lustrous tinge, brightest at the apical 

 margin. Apical scales lemon -coloured, merging into ferruginous 

 towards the anal angle. Cilia lemon- colour, becoming dull grey at 

 the anal angle. Posterior wings somewhat dull, pale grey, clothed 

 with coarse fuscous scales. Marginal scales dull, fuscous, with luteous 

 bases. Cilia pale grey. Abdomen shining grey ; the caudal tuft 

 pale straw-colour. $ Exp. al. 6-6^ lin. Anterior and posterior 

 wings as in the <$ ; the colouring warmer, and the lustrous markings 

 more distinct. 



An exceedingly common insect, but tolerably constant in its 

 colours and markings, which, however, vary a little in intensity. 



The imago appears from June to August, especially in Rose 

 gardens. It occurs throughout England, but more plentifully 

 in the south. In Scotland it is taken in the neighbourhood of 

 Edinburgh and at Dalmeny ; also near Dublin. 



The pupa is 3^ lines t in length, of rich ferruginous brown, 

 with a chestnut-coloured patch on each side, near the head. 



The larva is full-grown about the end of May, and is then 

 5 lines long ; of a pale yellowish -green colour ; the head shining 

 jet black ; shield black, divided by a pale dorsal line ; feeds on 

 various species of Rose, on the leaves, and sometimes in the 

 flower-buds ; occasionally very destructive. When about to as- 

 sume the pupa state, it frequently folds the terminal leaf longi- 

 tudinally along the midrib, and slightly fastens to it the con- 

 tiguous leaves ; it afterwards goes into pupa at the base of the 

 folded leaf, but before the imago emerges it wriggles to the top, 

 and the puparium may be found projecting almost wholly out 

 of the leaf. 



2. Forskaleana, Linn. Alis anticis testaceo-flavis aurantiacis reticu- 

 latis ; medio costae striga, macula magna ad marginem dorsalem 

 margineque apicali saturate cinereis ; posticis flavis, basi albican- 

 tibus. rf Exp. al. 5-7 lin. 



Head and face pale yellow. Eyes obscure brown, with a velvety 

 appearance. Palpi above, beneath, and between, yellow ; at the sides, 

 orange at the apex. Antennae yellow, paler beneath. Thorax and 

 patagia yellow, with a transverse orange -coloured band across. An- 

 terior wings yellow, thickly reticulated with red brown or orange. 

 On the dorsal margin is a large oblique dusky-grey blotch, extending 

 to the middle of the wing ; meeting this in a contrary direction is a 

 straight oblique streak, irrorated with fuscous ; apical margin irro- 

 rated with iron-grey ; sometimes the dorsal patch is only faintly re-
