Several specimens from Yokohama and Yesso in Fryer's 

 collection. Also recorded from Tokio. 



Cidaria minna, Butl., is most certainly a small form of 

 G. suffumata. One of my Japanese specimens measures only 

 24 millim. in expanse. 



The species is common in several localities in Western 

 China. 



Distribution. Europe; Altai; Japan; Yesso; Western 

 China. 



Larentia nitidaria, sp. n. 



Male. Primaries silvery grey, with a dark chocolate- 

 brown basal patch limited by a curved white line, and a 

 dark chocolate-brown central fascia edged with white, which 

 is broad on the costa but narrow from middle to inner 

 margin ; this fascia is apparently broken into three parts, 

 comprising a large triangular costal portion enclosing discal 

 spot, a small median spot, and an upright blotch on inner 

 margin ; on the apical area there is a large chocolate-brown 

 patch, which is intersected by a wavy oblique white line 

 extending from apex to the central fascia, which it penetrates 

 for a short distance ; submarginal line white, most distinctly 

 seen on the apical patch referred to ; there is a reddish-brown 

 shade on the middle of outer marginal area, and the space 

 between the basal area and the central fascia is clouded with 

 blackish. Secondaries grey, suffused with brownish on basal 

 area, and traversed by three pale central lines and a sub- 

 marginal line, the latter wavy. Fringes of primaries dark 

 grey and of secondaries pale grey. Under surface : primaries 

 fuliginous, with indications of a dark central line agreeing 

 with the outer edge of the fascia of the upperside and a white 

 macular submarginal line ; secondaries greyish, with darker 

 central line and discal spot. Antennse slightly ciliated. 



Female. Similar to the male, but the secondaries appear 

 more like the primaries in colour, that is silvery grey. On 

 the under surface the dark transverse lines are edged with 

 whitish, and there are indications of other whitish wavy lines 

 on the secondaries. 



Expanse 40 millim. 



One example of each sex from Pu-tsu-fong, June. 



Hab. Western China.
