THE RINGLET

this is known as ab. obsoleta, Tutt. In others, only very 
small white dots remain—ab. caeca, Fuchs, a fairly common 
form in certain localities. Another type with the white dots 
encirded by yellow is known as ab. arete, Mill. Between these 
forms every gradation in the development of the ocelli occurs, 
until they attain an extraordinary size, with the white spots 
much elongated and the whole of the markings developed 
into large oval ocelli, sometimes measuring as much as 6 mm. 
in diameter; this is ab. lanceolata, Shipp., and is of con¬ 
siderable rarity. 
A unique example of ab. lanceolata of extreme beauty was 
captured by the Rev. A. T. Stiff in the New Forest in 1933, 
having the great oval markings equally developed on both 
surfaces of the wings. 
7 he ground colour of the under side also is very variable, 
ranging from a very dark rich brown to pale greyish-buff.’ 
Specimens with asymmetrical spotting frequently occur. 
A. hyperanthus is occasionally liable to partial albinism, 
generally having one wing only more or less whitish, but such 
aberration is unusual in this butterfly. 
As in all the Satyrids, gynandromorphism is extremely rare 
in this common species.
