352 LEPinOPTERA. 



an almost imperceptible ridge ; abdomen slender, reddish- 

 drab; lateral and aual tufts well developed, whitish-drab. 

 Fore wings rather elongated and ovate ; costa very flatly 

 arched, but more strongly so toward the apex, which is bluntly 

 angulated ; hind margin oblique, gently rounded ; dorsal 

 margin nearly straight ; colour very pale fulvous-brown, or 

 pale fawn-colour; basal line curved and indented, reddish- 

 brown, the enclosed space tinged with the same colour: first 

 line tawny, forming a sharp angle or tooth near the middle of 

 the wing, curved back, and again outwards at the dorsal 

 margin ; second line of the same colour, but much more 

 obscure, bulging strongly outwards above the middle, then 

 formed into a hollow curve to the dorsal margin, also faintly 

 edged outside with whitish-brown ; the enclosed space is 

 more tawny or red-brown, yet not conspicuouslj' so, forming 

 an obscure central band in which is a brown discal dot ; 

 hind-marginal area faintly shaded with tawny, and divided 

 by a faintly white rippled subterminal line ; cilia pale fawn- 

 colour. Hind wings long, evenly rounded behind ; silky 

 yellowish-wliitc. without markings, but with a faint fulvous 

 shade along the hind margin ; cilia yellowish-white. I-"'emale 

 rather larger, quite similar, except that the autennaj are 

 threadlike. 



Undersides of all the wings soft silky ochreous- white : a 

 brown spot on the costa of the fore wings indicates the faint 

 second line; beyond this is a still fainter transverse line; 

 another crosses the middle of the hind wings forming a con- 

 siderable curve. Body and legs pale brown. 



Usually varying only a little in the colour and distinctness 

 of the central band of the fore wings ; but I have seen a 

 specimen, taken in (iloucestershire, which a]>]iears to belong 

 to this species, in which the ground colour is leaden-brown 

 with faint clouds of the usual yellowish-brown colouring 

 between the nervures ; the central band broken up into 

 blackish-brown ovate blotches, those near the dorsal margin 

 the most distinct ; and the discal spot large. Hind wings
