1. conchana, Hiib. Alls anticis rufo-cinereis, fusco-strigatis ; fasciis 

 tribus maculaque dorsali, ante angulum analem, aureo-brunneis ; 

 costa strigis albidis geminatis ; posticis griseis. rf Exp. al. 

 8-8| lin. 



Head and face dull brown, the former palest behind. Eyes black. 

 Palpi as long as the head, fuscous, paler at the base above. Antennae 

 fuscous. Thorax fuscous, banded with deep brown. Patagia : at the 

 shoulder deep brown ; apices and margin pale. Anterior wings 

 glossy, drab, or rich cream-colour, with chocolate-brown markings. 

 At the base is a streaky, mottled patch, extending one-fifth along 

 the costa, and nearly a third along the dorsal margin ; its posterior 

 edge obtusely angulated in the middle. Before the middle of the 

 costa commences an irregularly-shaped fascia, which terminates at 

 the middle of the opposite margin; its inner edge is tolerably 

 straight, but posteriorly it dilates, and is produced into two sharp 

 angles ; its origin and termination of equal breadth. At the anal 

 angle is an obtuse conical patch ; above the anal angle, and origina- 

 ting upon the apical margin, is a broad band proceeding obliquely 

 towards the costa, slightly dilating towards its apex. On the costa 

 are six geminations with chocolate interspaces: two before the central 

 fascia, which are clearly produced in lustrous streaks to the dorsal 

 margin ; the other four also lustrous and produced round the edges 

 of the principal markings. The apex and pale portions of the wing 

 suffused with pale ferruginous. Apical scales glossy, with umber 

 tips, and drab bases. Cilia glossy, iron-grey at the apex ; before and 

 beyond the anal angle the interspaces drab. Posterior wings some- 

 what dull, pale grey, with a slight pearly tinge at the base, and 

 merging into pale fuscous at the apex. Marginal scales and cilia 

 glossy ; the former fuscous, with paler bases ; the latter dull, cream- 

 colour, sometimes slightly fuscous. Abdomen pale fuscous, the caudal 

 tuft tawny. $ somewhat smaller than the tf , with the markings on 

 the anterior wings darker. 



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

 markings. 



The imago appears in July, and flies at sunset; it occurs at 

 Birch and Darenth Woods, Monkswood, Epping and New 

 Forests ; at Mickleham, and on the Downs beyond Croydon ; 

 in Gloucestershire, Cheshire, &c. ; also at the Black Forest in 

 Perthshire.

 saturatioribus. <? Exp. al. 7-8 lin.
