TORTRICINA. 19 



1 . semifasciana, Haw. Alls anticis griseis ; nebulis saturatioribus ; 

 maculis duabus costalibus (basi una, altera pone medium) fuscis 

 nigro-punctatis ; posticis griseo-fuscis, margine saturatioribus. 

 c? Exp. al. 8-9 lin. 



Head fuscous, darker behind antenna. Face fuscous. Eyes 

 black. Palpi above, at sides, and beneath, hoary; between paler. 

 Antennas fuscous. Thorax pale fuscous, streaked transversely with 

 dull brown. Patagia fuscous at base, somewhat hoary in the middle, 

 and paler at the apex. Anterior wings dull, ashy grey, palest at 

 the apex, with numerous pale fuscous, undulating, transverse, in- 

 terrupted streaks, most distinct on the costal and dorsal margins. 

 Near the base of the costais a short, pale, dull fuscous fascia margined 

 with darker brown ; in the middle of the costa is a large, irregular, 

 somewhat quadrate fuscous patch, bordered and dotted with dark 

 brown, and having the inner edge broadly and sharply black. In 

 the middle of the subapical portion of the wing are several obscure 

 brown spots placed on the nervures of the wing. Apical scales 

 deep fuscous, with the apices and bases pale grey. Cilia pale 

 fuscous. Posterior wings shining, fuscous, deepest at apex. Marginal 

 scales fuscous, with luteous bases. Cilia grey, with a fuscous tinge. 

 Abdomen pale fuscous grey. $ Exp. al. 9J-10 lin. 



This species is far from common, but in some places it is 

 occasionally taken in plenty. It does not vary. 



The imago appears from June to August about Sallows and 

 Willows. It occurs in Kent and Hampshire, at Wandsworth, 

 formerly in Battersea Fields, and in many places round London. 



The larva feeds on various species of Sallows and Willows, in 

 the young shoots and in the catkins. 



2. Hartmanniana, Linn. Alls albidis, subnebulosis ; fasciis duabus 

 interruptis fusco-nigris, una ad basin, altera pone medium, ob- 

 liqua, in qua linea atra ; posticis griseis. <$ Exp. al. 8-9 lin. 



Head and face pale rusty brown, the latter somewhat paler below. 

 Eyes black. Palpi above, at sides, and at apex, beneath, dark hoary 

 grey ; the bases beneath and between drab. Antennas fuscous. 

 Thorax pale fuscous, streaked transversely with dusky brown ; the 

 bind tuft dull brown. Patagia coloured like the thorax. Anterior 

 wings dull, pale drab ; the costa widely alternated with pale brown ; 

 near the base is an interrupted curved fascia of umber colour and 

 black. The central fascia is umber- coloured, mottled with black, and 

 interrupted longitudinally in the middle ; it is widest on the costa, and 

 on attaining the dorsal margin curves inwardly, running along it to 

 the base, thus enclosing, in conjunction with the basal fascia, an 

 oblong-ovate space on the median fold, marked with three dots. In 

 the apical region are some curved streaks, the darkest bearing one or 

 two black spots. Marginal scales umber, with the bases and apices
