may be added to variations common to corydon and acyon, and not to 
icarus and bellary us, an occasional aberration in aegnn and corydon, 
showing a few black spots additional to the discoidal spot on upper

scaling allowing some reproduction of markings of undersides on 
uppersides, probably most commonly in icarus.
