where the band expands); the band is limited externally by the submarginal, 

 white, zigzag line; an oblique, blackish, apical streak, succeeded by a row 

 of submarginal linear dots; the marginal, black, interrupted line distinct; 

 fringe gray, with a mesial darker line, and checkered with dark gray opposite 

 the ends of the venules. Hind wings whitish, with two fain! miter lines, 

 the inner ut' the two consisting of dark venular dots; discal dots distinct; 

 beneath, the lines are faintly reproduced, (he discal dots are quite distinct, 

 and the costal half of the outer yellowish hand faintly appears ;• the dark 

 marginal line is distinct, and the dark checks in the fringe are darker and 

 more distinct than above. On the hind wings, the inner line is distinctly 

 scalloped. Abdomen with two tows of black spots.

This species may be at once recognized by the two broad yellow bands 

 on the fore wings, and by the deep discal sinus. It varies greatly in the 

 contour of the outer edge of the basal space; the scallops being either slightly 

 marked or acute and prominent. The width of the inner yellow band varies 

 much, being one-half as wide in some as in others. The inner edge of the 

 mesial band is scalloped with different degrees of distinctness, while the band 

 itself is in some specimens three times as wide as in others. The depth and 

 size of the discal sinus vary greatly, as also the form of the scallops and 

 the depth and 'distinctness of the broad submedian sinus. The form of the 

 fore wing in only one specimen approaches that indicated by Guenee, being 

 very square at the apex. The two White Mountain specimens would easily 

 be mistaken at first for different species: in one, the inner yellow hand is 

 half as wide as in the other, and the discal sinus is very small, while in the 

 other very large : and the mesial band is twice as wide in one as in the other, 

 with two distinct lines running through the middle of the space. The 

 specimen (female) from Vancouver's Island differs most from the others in 

 the basal yellow band being much wider than usual, with the edges irregu- 

 larly and sharply scalloped; the outer yellow hand is wanting, the outer third
