area of primaries and outer marginal area of all the wings 

 suffused with violaceous brown. On the primaries the blackish 

 line limiting the basal area is biangulate below costa and 

 very oblique from median nervure to inner margin; outer line 

 oblique, blackish, appearing to commence below apex in the 

 undulated and diffuse blackish submarginal line and preceded 

 by a slightly wavy brown line, which limits the outer mar- 

 ginal area. Secondaries have a brown central line followed 

 by a blackish one parallel with it ; submarginal line diffuse, 

 blackish ; all the wings have a black discal dot, but that on 

 secondaries most conspicuous. Under surface similar to 

 above, but the basal two-thirds of secondaries paler. 



Expanse 37 millim. 



One male specimen from Chang-yang, June. 



Bab. Central China. 



Closely allied to X. subspersata, Feld., but the transverse 

 markings rather different, the outer line on primaries ter- 

 minates on outer margin below the apex ; outer margin of 

 secondaries is slightly crenulate, with a distinct projection 

 above the middle. 



Genus APERICALLIA, nov. 



Palpi porrect, densely hairy, extending considerably beyond 

 the frons. Antennae of male bipectinated to apex. Posterior 

 tibiee not dilated, with all spurs present. Primaries have 

 the outer margin slightly concave below apex, angled at 

 fourth vein, thence oblique. Secondaries have the outer 

 margin slightly angled at middle. Venation similar to that 

 of Pericallia. 



Type A. bih'nearia, sp. n. 



Apericallia bilinearia, sp. n. 



Primaries whitish grey, tinged with lilacine and freckled 

 and clouded with fuscous ; the central area is traversed by 

 two dusky-brown, almost blackish, lines : the inner one very 

 slightly curved and the outer one oblique and followed by 

 two blackish spots. Secondaries pale whity brown, pow- 

 dered with fuscous, and traversed by a dark brown line, 

 which tapers towards but does not attain the costa. Fringes 

 brown on primaries, grey on secondaries, merging into 

 brown at anal angle. Under surface ochreous brown, freckled 

 with blackish ; transverse lines and markings generally as 

 above, but the outer line of primaries is followed by a ferru- 

 ginous patch on costa ; the secondaries are whiter and have
