56 TOllTRICINA. 



This species varies considerably in size, and somewhat resem- 

 bles Tortrix Forsterana, but is distinguished from it by its tawny 

 hue and larger and more conspicuous spots. It occurs less 

 sparingly than L. Forsterana. 



The imago appears in June at Darenth Wood, Epping Forest, 

 Coombe Wood, in Cheshire, &c. 



The larva feeds on the Hazel, Birch, and Oak. 



2. musculana, Hiib. Alis anticis griseis ; basi macula angulata, 

 medio fascia obliqua maculaque costali brunneis ; posticis fuscis. 

 c? Exp. al. 7-8 lin. 



Head fuscous. Face paler. Eyes black. Palpi longer than the 

 head ; above and at sides fuscous, paler at base, pale drab beneath 

 and between. Antenna? alternated with drab and brown. Thorax 

 and patagia fuscous, the latter slightly paler at the apex. Anterior 

 wings dull drab, marked and reticulated with fuscous and brown ; 

 at the base is a pale fuscous patch (sometimes obsolete or nearly so), 

 with its posterior border angulated or rounded, and edged with 

 castaneous brown. At the middle of the costa commences a rich 

 golden-brown fascia, which dilates soon after its origin, occupying 

 about twice the space upon the dorsal margin, is darkest and most 

 sharply denned anteriorly, where it is also streaked and spotted with 

 umber ; in the subapical portion of the costa is an undefined, some- 

 what triangular, fuscous cloud ; and sometimes below this are two 

 undulating umber streaks produced towards the anal angle ; the 

 pale portions of the wing more or less streaked or reticulated with 

 brown, particularly the apical portion. Apical scales drab, alter- 

 nated with patches of dark brown. Cilia glossy, tawny, and be- 

 coming iron-grey at the anal angle. Posterior wings and marginal 

 scales glossy, fuscous, with a bronze lustre, especially at the apex. 

 Cilia pale drab. Abdomen rich fuscous, the caudal tuft tawny. 

 5 Exp. al. 9-10 lin. Anterior wings paler, and with the central 

 fascia sometimes angulated and more suffused posteriorly. 



A common species, variable in size and in the intensity of its 

 colours, particularly in the 5 . In appearance coming nearest 

 to Tortrix transitana } both in size and markings ; the central 

 fascia, however, is more distinct, broader, and less interrupted. 



The imago appears in May amongst Brambles, and occurs at 

 Darenth, Coombe, Birch, West Wickham, and Plumstead Woods, 

 and other places in the metropolitan district, at the New Forest, 

 in Cheshire, Somersetshire, &c. ; it also occurs in the vicinity of 

 Edinburgh, and near Dublin and Enniskerry in Ireland. 



The larva feeds on the Bramble, between united leaves, and is 

 full-fed about September ; it then spins a slight cocoon, and 

 changes into pupa about November.
