{Continued from Vol. xix, puffe 136). 



TorfrLv icterana. — Larva three-quarters of an ineli in length ; 

 cylindrical, active. Colour smoky-black, with the spots pure v^'hite, 

 large, and prominent ; head and both plates jet black, collar of second 

 segment white. These larvse were sent by Mr. Dunsm ore, formerly of 

 Paisley, and fed on Gentaurea nigra, in the middle of June, emerging 

 in July. 



The larva of paleana, Hb. (flavana, H.) — of which, icterana, 

 Frol., is made by "Wocke a variety — is said by Zeller to be " dull black, 

 with the incisions of the segments palev, with deep Hack raised dotsy 



Tortrix vihiirnana, Schiff. — Larva cylindrical, extremely active. 

 "When young, pale gi'ey or dark olive-green, changing to pale olive- 

 green or greenish-black, and having a paler or yellowish line above the 

 lege. Spots distinct, white, with white hairs ; head light brown with 

 two triangular black spots behind ; dorsal plate very pale brown, edged 

 at the sides with black, and with a triangle of black dots in the middle ; 

 anal plate pale brown edged with black. Feeding at the end of May 

 and early in June on Vaccinium viyrtillus. Erica cinerea, and other 

 plants on heaths. Pupa black, in a white silken cocoon loosely made 

 made among heath-twigs. 



Wilkinson desci'ibes the larva as " tvliite, with black spots" — 

 a remarkable looking larva apparently ! ! Zeller's description agrees 

 very nearly with mine. He gives as food-plants^ " Viburnum, Vacci- 

 nium, Andro7neda, and Ledum palust re." 



Tortrix viridana, L. — Larva not very active, plump, and tapering 

 behind. Colour, pale green, or pea-green, with the spots distinct and 

 black ; head and legs shining black ; dorsal plate green or grey, with a 

 white collar and black dots behind ; anal plate green or pale yellowish. 

 A far too well known larva, feeding generally on oak, but sometimes 

 on maple, rolling the leaves into cylinders ; Hofmann says also on 

 sallow and So7-bus, and that there is a brown spot on the eighth 

 segment. This is not always visible. 



Tortrix Forsterana, Fab.^ — Young larvfe were found on January 

 15th feeding between united leaves of ivy {Hedera helix), gnawing 

 away the surfaces of both leaves, but leaving the external skin un- 

 touched, apparently indifferent to severe frost, from which they were
