c? ? . A pale form, not always distingnishable from the pale individuals of 

 m. memphron. The forewing of a nuiform grey colour, with the transverse lines 

 more or less obliterated ; the black oblique bar at the end of the cell, the apical 

 half-wing, the costal markings midway between the two — the costal part of the 

 discal lines — and the two discal streaks very prominent on the pale ground. In 

 two of our specimens, without further indication of locality than Japan, those black 

 markings are much enlarged, the two discal streaks being only separated by 

 the vein, and the costal and apical markings being twice as heavy as in ordinary 

 individuals.
