 waiitin<;- in the specimens examined. Transverse anterior line upright 

 or nearly so, even, brown, usually i)receded by a pale shade, quite often 

 outwardly diftusc. Transverse posterior line narrow, brown, followed 

 by a broader yellow or whitish line, both even, usually nearly ui)right 

 or a little outcurved; but sometimes broadly outcurved over the cell 

 and corresi)oiulingly drawn in below. Subterminal line pale, irregular, 

 rarely continuous, sometimes punctiform and often obscured in the 

 lower part of its course, preceih'd and detined by a dusky shade which 

 is also sometimes broken into spots, but is more usually diffuse, dark- 

 ening the entire subterminal space. A series of more or less distinct 

 terminal Idack dots or lunules. A broad, diffuse, iii)right median 

 shade is present in some specimens and varies to total obsolescence. 

 Orbicular small, round, yellow, often absent, rarely black. Keniftn-m 

 upright, narrow, somewhat constricted, yellow, with black points, a 

 black lunule, or entirely invaded by black. Secondaries paler, dirty 

 gray with an even central pale line preceded by a dusky shade, and 

 an irregular, pale subterminal line wdiich is often obsolete. Beneath, 

 coarsely powdered, with a vague discal lunule on secondaries, and on 

 all wings a brown extra-median line and often an exterior pale line. 

 The latter is, however, quite fre(]uently lost altogether and yet more 

 often lost on the primaries alone. 



Expanse of wings, 20 to 30 mm. = 0.80 to l.l'O inches. 



Habitat. — Canada to Alabama, to Texas, New Mexico; New Y(ni< 

 and New Jersey, July and August; District of Columbia, Indiana and 

 Illinois in July; Texas in May and June. 



This is our most common and widely distributed species, and it is at 

 the same time the most easily recognizable. The clear, even trans- 

 verse posterior line is unique in the genus, and this is continued to the 

 secondaries, giving some specimens a very distinct geometriform 

 appearance. The line of variation has been somewhat indicated in 

 the description, and while it is considerable it is not confusing, because 

 the characteristic median lines dominate everything. The difference 

 in sex is strongly marked in the pali)al structure. In the male they 

 are quite decidedly recurved, while in the female they are straight or 

 at most ol>li(]iU'.
