this powdering is thinner on the inner and marginal portions 

 of the outer half of the wing, thus giving the appearance of 

 central and marginal bands. 



Female. Similar to the male, but the fascia of primaries 

 is hardly darker than other portions of basal two thirds. 



One example of each sex from Moupin, June. 



Hab. Western China. 



L/arentia rotundaria, sp. n. 



Outer margins of all the wings have a very rounded ap- 

 pearance. Primaries have the basal three fourths dark grey, 

 traversed by wavy darker lines, and divided towards the 

 base of the wing by a dark-edged, narrow, pale grey band, 

 the outer edge of which has an angular projection below the 

 middle ; the outer limit of this dark area is undulated, con- 

 spicuously lobed below the middle, and edged with white on 

 the costa ; the outer marginal area is silvery grey, clouded 

 with dark grey exteriorly ; there is a short oblique blackish 

 streak from the apex, and the submarginal line is represented 

 by a series of white marks on costa and a series of white dots 

 to inner margin. Secondaries smoky silvery grey. Fringes 

 dark grey. Under surface smoky grey : primaries have an 

 abbreviated white line, shaded with dusky, from costa, and 

 a macular white submarginal line ; secondaries have a dusky 

 wavy central line and an interrupted white submarginal line.
