166 TORTRICINA. 



of the costal patch and the brick-red colour of the patch itself, 

 which in the latter species is almost always umbreous; the 

 ground-colour, too, is considerably less ochreous. 



There is one well-defined variety, the Tortrix latifasciana of 

 Haw., L.B. 414, No. 65, which has a rhomboid brick-red patch 

 at the base, followed by an abbreviated streak of the same colour, 

 originating on the dorsal margin ; the costal patch is much 

 amplified, and extends to, or nearly to, the opposite margin. 



The imago appears from August to September, among Sal- 

 lows and Willows. It is taken at Birch, Coombe, Darenth, Wick- 

 ham, and Meonstoke Woods, the vicinity of London, Cheshire, 

 in the north of England, in Scotland, and in Ireland. 



The larva feeds on the Sallow and Willow, and Mr. J. H. 

 Harding quotes the Meadow Sweet (Spirtea ulmaria) as the food- 

 plant. It is to be found in plenty on the Willows in Plaistow 

 Marshes, near London. 



2. comparana, Hub. Alls anticis ochraceis ; macula trigona medio 

 cost* saturate fusca ; striga abbreviata obliqua ad marginem dor- 

 salem punctulisque elevatis fuscis ; posticis griseis. tf Exp. al. 

 7-9 lin. 



Head and face fuscous, sometimes dull ferruginous. Eyes black. 

 Palpi above and at the sides same colour as the head, whitish be- 

 neath. AntennaB fuscous. Thorax and patagia fuscous, sometimes 

 ferruginous. Anterior wings reddish ochre, with a large umbreous 

 triangular patch on the costa, with a leaden lustre, enclosing a small 

 dull ochreous space at the margin, and sometimes a still smaller 

 one nearer the apex. Near the base on the dorsal margin is a 

 short, dusky, oblique streak, with a small dark-brown tuft of elevated 

 scales at its apex, followed by two or three others of the ground- 

 colour of the wing ; below the apex of the triangular costal patch 

 are several tufts, and one near the middle of the dorsal margin ; 

 towards the apex are a few others ; the apex itself slightly reticulate 

 in appearance. Apical scales and cilia concolorous, but slightly paler, 

 especially at the anal angle. Posterior wings pale fuscous grey. 

 Marginal scales pale fuscous, with luteous bases. Cilia pale fuscous 

 grey. Abdomen pale fuscous; the caudal tuft dull straw-colour.

 warmer tint. 



In size and general appearance somewhat resembling P. Schal- 

 leriana } but is much more ochreous in the ground-colour of the an- 

 terior wings, and the costal patch is almost always umbreous. It 

 is not subject to much variation. 



The imago is frequently taken in company with P. Schal-
