followed by an irregular olivaceous patch on dorsal half of wing, beyond which 

 there is a blackish spot on end of cell, and one farther out on the dorsal margin; 

 middle of costa also with a dark pateh, obscured by the blackish shading. Fringe 

 dark; hind wing pale in the typical form, gray in the dark phase. 12 mm. 



June and July. 



New Hampshire to North Carolina and Manitoba. New York: Newcomb, Rock 

 City (Cattaraugus County), Batavia. 



35. 0. griseoalbana Walsingham. Whitish; costal edge dark gray, cut with 

 white toward apex; outer edge blackish, preceded by white striae. Base dark 

 gray, except at costa; a pale rounded gray patch at middle of dorsal margin, and 

 a smaller black one before hind angle, with some black striae on the white ground 

 between them. Hind wing dark. 15 mm. (Exartema). 



June to August. 



New Hampshire and Massachusetts to southern Ohio. 



36. 0. malachitana Zeller. Dull crimson, a little powdery, thorax and base 

 of wings dull powdery gray. A large olive patch reaching from end of cell almost 

 to base of wing and down to below A, striate with whitish on costa, and denned on 

 the whole lower side by an evenly curved whitish line. A horizontal brown crescent 

 from end of cell to outer margin, concave downward, and a spot at beginning of 

 dorsal fringe. Fringes concolorous; hind wing mouse gray. 15 mm. 



Larva on persimmon. 



Virginia and Pennsylvania to Quincy, Illinois, and south. 



37. 0. interruptolineana Fernald. Wood-brown, shaded with dull rose and violet. 

 Basal half light grayish toward costa, ending abruptly at a square brown median 

 costal patch, and edged below with a sharply denned dark brown bar extending 

 from inner margin near base a third way to apex. An irregular brown patch 

 extending from cell opposite the median costal spot to middle of outer margin, 

 constricted so as to appear composed of three partly fused patches, of which the 

 first may fuse with the median costal spot, and the middle one may be hardly 

 darker than the ground. Apex often brown, cut off by a pale stria. 13 mm. 



May; July and August. Larva on Vaccinium. 

 New Hampshire to District of Columbia. 



38. 0. osmundana Fernald. Dull gray-brown. A large yellow-brown patch 

 extending from middle of inner margin two -thirds way to costa; a dark brown 

 patch, half as large, at anal angle; a subterminal bar and a short oblique bar 

 from middle of costa, all fairly clean-cut and finely pale-edged. Hind wing mouse 

 gray. 10 mm. 



Larva on Osmunda regalis; also reported from seeds of Ambrosia. 

 Maine; District of Columbia. 



39. 0. ochromediana Kearfott. Base chocolate brown; the outer boundary irregu- 

 lar and farther out on costa; median area even ochre yellow, twice as wide on 

 inner margin as on costa; outer two-fifths chocolate brown, a little mottled and 

 shaded with gray, but without clearly defined patches. Hind wing mouse gray. 

 10 mm. 



July. One New Hampshire specimen is suffused with ochre yellow, with the 

 usual marks just traceable. 



New Hampshire to Pennsylvania. 



40. 0. murina Packard. Mouse color, dusted thickly with luteous scales. Head 

 and thorax darker; fore wing with small obscure pale luteous costal spots, becom- 

 ing paler toward apex; forming a very vague fascia from beyond middle of costa 

 to anal angle; iringe also pale. Hind wings pale, dusky toward apex. 20 mm. 



Of this species I have seen only a single fragmentary specimen. It appears to 

 be a suffused form of the capreana group. 



Straits of Belle Isle, Labrador. Reported as common.
