NYMPHALLDAE: SATYRLNAE. 1779 



upon it in tlie interspaces; the inner border of tlie raliUlle baud is formed of aseries of 

 right angles from tlie costal border till it has passed the median uervure; in the space 

 above the cell it forms a right angle whose limbs arc equal, projecting borderwards, 

 in the cell one whose limbs are unequal projecting basewards, the short limb being the 

 continuation of that of the interspace above, extending to the middle of the cell, whence 

 it is directed to the origin of the first median nervule, is again bent here at right angles 

 before reaching it, and continues to the internal nervure, whence it extends, bent 

 slightly borderwards, to the inner margin ; the outer border of the band starting from 

 the costal border of the wing passes in one arch to the second subcostal nervule, here 

 extends borderwards to the middle of the interspace opposite the extremity of the cell, 

 and thence moves in a gradual crenulated curve, passing just beyond the extremity of 

 the cell to the inner border ; the band is broader than in most species of the genus, 

 and is especially so on the median nervures ; the nervures are all distinctly flecked 

 with white. Expanse of wings, 50 mm. 



This butterfly appears to be confined to the high northern regions of the 

 eastern half of the continent, being thu.s far known only from Rupert House* 

 at the southeastern extremity of Hudson Bay and Car'bonear, Newfound- 

 land. Nothing is known of its history or seasons.

Imago. Head covered with mouse brown and gray hairs, the fringe of the palpi 

 with many Ijlack ones; the antennal stalk black brown, narrowly annulate at the base 

 of the joints with white, the club luteous, a little infuscated. 



Wings above dark brown with a chocolate tinge ; the outer Iwrder witli a faint, slen- 

 der, pre-marginal, somewhat lunalate, narrow, blackish brown stripe, not greatly 

 darker than the ground, and on the fore wings limiting in the lower half of the wing an 

 exceedingly broad orange yellow band which traverses the wing beyond the middle, of 

 nearly equal width throughout and extending from the costal to the snbmedian nervure, 

 its inner margin gently arcuate or bent in the middle and lying wholly beyond the cell; 

 in the upper outer corner of tliis broad belt and occupying the whole width of the low- 

 est subcostal interspace is a large, round, black spot with a blurred margin, containing 

 a distinct, though small caernlean blue pupil ; in addition there is often in the middle 

 of the lower median interspace a black point, or sometimes an incomplete ocellus. On 

 the hind wings there is no such yellow band, but at a corresponding point of the lower 

 median interspace, that is, a little bej'ond the middle of the interspace, is a black ocel- 

 lus with a brownish yellow areola and a bine pupil ; the areola sometimes obsolete, the 

 whole nearly or quite as large as the permanent ocellus of the fore wing; fringe of 

 all the wings of the ground color but on the lower portion of the outer margin of the 

 fore wings a little paler; in .all the wings preceded by a delicate black line at the ex- 

 treme base of the fringe, and this, on the hind wings, by a pale brown line of similar 

 width.
