THE CHECKERED SKIPPER

with more or less rounded spots. The fringes are black along 
the inner half and fulvous-yellow along the outer half; above 
the eye is a tuft of black hairs. 
(Under Side.) The under side of the fore wing is amber- 
yellow and the markings are similar to those on the upper 
side, but paler; the hind wing is densely dusted with 
yellow scales. 
Female. The female is rather larger than the male, and 
the spots are paler, especially on the hind wing; otherwise 
the sexes are similar. 
Life of Imago. The life of this very active little butterfly 
is probably between two and three weeks. 
Aberration. This species is liable to considerable aberra¬ 
tion in the development of the markings. Sometimes the 
spots are confluent and almost obliterate the dark markings, 
while in other specimens the spots are greatly reduced both 
in size and number. Gynandromorphism in the Hesperiidac 
is of extreme rarity.
