BUTTERFLIES OF MAINE. 15 
37. CHronosBas JuTTA, Hueb. 
Chi-on-o’-bas jut’-ta. 
Expanse of wings, two and one-fourth inches. 
Upper side of wings, dark brown with four small black 
spots ringed with yellowish, nearly parallel with the outer 
margin of the fore wings. The two middle ones are scarcely 
visible. An irregular black band along the lower side of the 
median nervure in the males. The hind wings have a series 
of yellowish spots inside of the outer border, the first of 
which has a small black eye-spot on it, with a whitish pupil. 
Under side of hind wings costal and apical parts of fore 
wings marbled with grayish, dark brown and black. The 
rest of fore wings as above with the eye-spots reproduced. 
All the fringes pure white interrupted with black’ at the 
ends of the nervules. Head, thorax and abdomen, black with 
brownish hairs. 
This northern butterfly, which has never been taken else- 
where within the limits of the United States, has been taken 
for several years early in the month of June on a large bog 
in Orono. It occurs in the northern parts of both Europe 
and America, but its food plant has not yet been discovered. 
Its near relative Chionobas semidea, Say, on the White 
Mountains of New Hampshire, feeds on Carex rigida, and, 
as there are many species of Carex on the above named bog, 
it is possible that the larva of our species feeds on some of 
them.
