A. clarescens, Grote (not Guen.). 



Primaries above chalky white, irrorated and clouded with 

 sandy greyish or yellowish and grey njixed, somewhat after 

 the ma.ni\ev oi A. jHoruIa; 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 reuiforra 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 otiier respects the 

 species is like A.furcifera, the male having whitisii and the 

 female more or less golden-brown secondaries with the usual 

 markings. Expanse of wings 40-45 millim.
