A common insect in Japan and Corea. My collectors met 

 with it in all the localities they visited in Central and 

 Western China. 



The Japanese specimens (referable to conferenda, Butl.) 

 are generally darker in colour, but they all have the charac- 

 teristic markings of consortaria. 



The Chinese specimens are tinged with cinnamon-brown, 

 and some examples are much larger than the type. 



Distribution. Europe; Amur; Askold; Corea; Japan; 

 Western and Central China. 



Boarmia corticaria, sp. n. 



Male. Pale brown, powdered with dark brown. Primaries 

 clouded with blackish before the whitish submarginal line : 

 first transverse line wavy, second oblique throughout the 

 middle of its course, but dentate below costa and above inner 

 margin, both black ; between these lines there is a black 

 spot and a blackish central shade, terminating in a dark 

 brown cloud on inner margin, and beyond the second line 

 there is a dark shade connecting the blackish clouding before 

 submarginal line with a smaller cloud on inner margin; from 

 this shade there are projections along the median nervules. 

 Secondaries have a black central spot, two transverse lines, 

 and a whitish submarginal line ; the latter is shaded inwardly 

 with blackish and the second black line is bordered outwardly 

 with dark brown. Fringes brown, preceded by a black 

 lunulated line. Under surface pale brown, irrorated with 

 darker brown ; there is a black spot and a broad submarginal 

 fuscous-brown band on each wing ; the latter is preceded by 

 a brownish line, which is bifurcated towards abdominal 

 margin and followed by some whitish patches on the outer 

 marginal area. Antennae bipectinated. Thorax agrees with 

 wings in colour ; collar dark brown ; tip of abdomen with a 

 tuft of long silky pale brown hairs. 



Female. Rather paler than the male on both surfaces.
