A. clarescens, Grote (not Guen.). 



Primaries above chalky white, irrorated and clouded with 

 sandy greyish or yellowish and grey mixed, somewhat after 

 the manner of A. moruta; the submedian basal black streak 

 has somewhat the character of that of the true A. clarescens, 

 only it is more elongated, sharply defined, and its upper 

 margin is regularly tridentate; the reniform and orbicular 

 spots are narrowly black-edged ; the twin discal or post- 

 median lines are sigmoidal and dentate-sinuate, the outer line 

 being partly black ; the subapical longitudinal dash is vague 

 and diffused, and the dagger- mark has a brown background, 

 which gives it a blurred appearance ; in other respects the 

 species is like A.furci/era, the male having whitish and the 

 female more or less golden-brown secondaries with the usual 

 markings. Expanse of wings 40-45 millim.
