650 (1). Oxygrapha tunicatana, sp. n. 



Antennce greyisli cinerous, paler beneath. Pa/p^' greyish 

 fusconS; very pale ochreous beneath. Head and thorax dark 

 purplish fuscous. Fore wings rather narrow ; dark purple, 

 or purplish fuscous, with scattered groups of raised scales, 

 the largest and most conspicuous crossing the middle of the 

 fold, with a few greyish cinereous scales at its outer end and 

 a small group of detached similar scales above it ; the costa 

 strongly fringed before the middle with mixed purplish 

 fuscous and greyish cinereous scales, giving it a more than 

 naturally depressed appearance ; at and beyond the middle of 

 the costa are some groups of greyish cinereous scales, and 

 from the tornus to the apex a large patch of greyish cinereous 

 extends widely to above the middle of the wing and narrowly 

 to the costa before the apex, this patch is strongly mixed 

 with rich brown scales, the lines of the veins running through 

 it being slightly indicated ; cilia chestnut-brown, tipped with 

 pale cinereous, a reduplicated pale cinereous line along their 

 basal half, a small purplish grey dot at the tip of the apical 

 cilia, with a slightly paler one below it. Underside with the 

 costa streaked obliquely with pale cinereous and fuscous alter- 

 nately. Exp. o?. 22mn). Hind wings ^a.\e, shining, whitish 

 grey, tinged with very pale cinereous towards the apex ; cilia 

 very pale cinereous. Abdomen pale cinereous. Legs whitish 

 ochreous, hind tarsal joints shaded above with bands of grey. 



Type, ^ (60195) Mus. Wlsm. 



Hah. Japan — Ikao {Leech, 1886) ; Hondo — Oiwake, X. 

 1886 [Leech). Two specimens. 



This is probably a variable species : the specimen from 

 Oiwake is almost certainly a variety in which the dark 

 purplish fuscous colour is confined to a dark basal patch, and 

 having a roseate suffusion over the middle of the wing extend- 

 ing to the tornus ; the raised tufts are in the same position as 

 in the type.
