62 TORTRIC1NA. 



lin. Anterior wings dull, pale fuscous, but without the pale violet 

 tinge of the $ ; the curved patch at the base of the dorsal margin is 

 here represented by an undefined dark brown spot ; the central 

 fascia extends from the costa to the dorsal margin, narrow and 

 rather faint at its origin, then dilating widely towards the middle, 

 and afterwards gradually narrowing to its termination ; the curved 

 wedge-shaped streak near the apex, and that on the margin, as in 

 the <$ ; the edges of all these markings are undefined, and without 

 the bordering of drab scales ; the pale portion of the wing is streaked 

 transversely at the base, and reticulated at the apex ; apical scales 

 and cilia dark brown, both becoming paler at the anal angle. Posterior 

 wings fuscous, at the apex yellowish. Marginal scales fuscous, with 

 luteous bases. Cilia pale grey. Abdomen fuscous, the apex acute. 



This species resembles L. fulvana in size, but is distinguished 

 by the absence of yellow colour, and by the angulated anterior 

 edge of the central fascia in both sexes. It likewise very much 

 resembles L. Xylosteana, but is larger, and the ground-colour 

 of the anterior wings is darker, the marks more umbreous, and 

 the pale lustrous edges of the markings, as in this latter species, 

 are wanting. 



The imago appears in July, is somewhat local, and occurs but 

 sparingly. It has been taken, by beating, out of Poplars, Aspens. 

 Oak, Hazel, Birch, &c., at Darenth, Ardley, Swanscombe, and 

 Wickham Woods, Shustoke, in Warwickshire, &c. 



9. Xylosteana, Linn. Alls anticis griseo-testaceis, macula basi ; 

 fascia media lata ad costam bifida, alteraque postica brunneis 

 saturatis ; posticis griseo-fuscis, ad apicem flavescentibus. S Exp. 

 al. 8-8i. 



Head and face dull fuscous. Eyes black, shining. Palpi as long as 

 the head, above pale fuscous, at the sides ferruginous towards the 

 apex, yellow beneath. Antenna dusky brown, basal joint clothed 

 beneath with pale shining scales. Thorax dull, pale fuscous. Patagia 

 usually dull, pale fuscous, but with the base sometimes ferruginous, 

 and the apex paler than the thorax. Anterior wings shining, dull, 

 pale brown or fawn-colour ; near the base on the dorsal margin is a 

 rich brown oblong patch, extending obliquely to the middle of the 

 wing ; before the middle of the costa, commences the central fascia 

 of the same colour, darkest towards the apex, regularly undulate on 

 its anterior edge, and biangulated and dilating widely posteriorly, 

 ultimately attaining the anal angle ; the projection nearest the costa 

 tipped with black, or intense brown ; the usual semilunate patch on 

 the costa towards the apex is of a quadrate form, extending nearly 

 to the central fascia ; at the apex is a trigonate dark brown patch, 

 followed by another paler one below, which is acute, and points to 

 the apical margin ; the edges of the principal markings bordered
