104 Mr. J. H. Leech on 



971. Acronyda nigricans, sp. n. 



Head and thorax dark grey mixed with paler ; abdoineii fuseous- 

 grey. 



Primaries grey, clouded and suffused with darker grey and blackish ; 

 there are some blackish dots on the costa, and three white ones towards 

 apex ; transverse lines double, black, siinious ; the postmedial 

 line incurved below the middle and marked with white towards 

 inner margin ; submarginal line blackish, sinuous, interrupted and 

 edged with whitish ; reniform and orbicular stigmata outlined in 

 black, the former partly obscured by the blackish central shade and 

 the latter with a central blackish dot, a diffuse pale spot between 

 them ; there is a blackish transverse bar below the median nervure, 

 and a curved one, in a line with the last, from postmedial to outer 

 margin ; fringes dark grey, marked with black, and preceded by a 

 series of black > shaped marks. Secondaries white, the venation 

 fuscous especially towards outer margin ; fringes white preceded by an 

 interrupted fuscous line. Under surface of primaries fuscous, paler 

 on costa and on the outer margin ; secondaries white with a blackish 

 discal lunula and some dark scales on the costal area. 



Expanse 44-48 millim. 



One male specimen and four females from Wa-shan, 

 July. 



In one female example the basal area of the under 

 surface of primaries is pale fuscous. 



Habitat. WESTERN China. 



Perhaps nearest allied to the dark form of A. rumicis, 

 from which it is at once separated by the white secondaries. 

 From A. hrumosa, Guen., it can be distinguished by the 

 darker coloration and different marking of primaries, 

 especially with regard to the stigmata.
