TORTRICINA. 47 



transverse, interrupted, and undulating lines, especially on the costal 

 and dorsal margins ; the apical portion reticulated. Apical scales 

 dull, very short, dull brown at base ; apices clay-colour. Cilia also 

 dull, and coloured like the apical scales. Posterior wings pale 

 straw-colour, with a pale fuscous cloud at the anal angle ; the apex 

 slightly streaked with brown. Marginal scales slightly grey towards 

 the anal angle, straw-colour at the apex. Cilia whitish at the anal 

 angle, merging into straw-colour at the apex. $ Exp. al. 9-J lin. An- 

 terior wings with the markings somewhat darker than in the <$ . 

 Posterior wings with a pale grey cloud at the ana] angle. Marginal 

 scales grey, with luteous bases. Cilia pale grey at the apex, merging 

 into pale straw-colour at the anal angle. 



A rare species, much resembling L. heparana in the anterior 

 wings, which however are slightly broader, and the ground- 

 colour is not so dark ; the posterior wings are pale, like those in 

 L. semialbana. 



The imago appears in July, and has been taken near Lewes 

 by Mr. J. J. Weir : it occurs also at Monkswood (its original 

 locality) . 



The larva feeds upon Oak, from which it has been bred by 

 Mr. T. Brown of Cambridge. 



6. heparana, Schiff. Alis anticis testaceo-runs ; fusco reticulatis ; 

 fascia basi, media obliqua maculaque postica costali saturatioribus ; 

 margine posteriori fasciae medias dentata ; posticis cinereo-fuscis. 

 c? Exp. al. 8-10 lin. 



Head and face dusky red brown. Eyes velvety, dark plum-co- 

 lour. Palpi longer than the head, but of same colour above and at 

 sides, dull drab between and beneath. Antennae dull brown above 

 and beneath; the basal joint clothed with dusky drab shining scales 

 beneath, and dull brown above. Thorax and patagia dusky red 

 brown. Anterior wings pale red brown, with a purplish tinge on 

 the costal region, and deep ferruginous markings, which are thus 

 disposed ; at the base is a patch with an oblique angulated edge ; an 

 oblique fascia commencing at the middle of the costa, and extending 

 to the dorsal margin, within the anal angle : this fascia is narrowest 

 shortly after its origin, and widest in the middle, being obtusely an- 

 gulated on each edge. Between the central fascia and the apex, on 

 the costa, is a trigonate patch, most clearly denned on its anterior 

 edge ; the markings are mostly edged with a pale line, as in L. cin- 

 namomeana, and the whole surface is thickly streaked with fine 

 irregular dusky grey, interrupted, transverse lines, not assuming the 

 appearance of reticulations. Apical scales short, concolorous with the 

 ground-colour of the wing. Cilia : sometimes paler, at others darker 

 than the marginal scales, and merging into shining grey at the anal 

 angle. Posterior wings dull fuscous, darkest towards the apex. Mar-
