tlie inner line is rarely distinct, while the others are fairly well marked 

 in most instances, sometimes becoming' obsolete toward the costal mar- 

 gin. Beneath, varying greatly in color and in the distinctness of 

 maculation. Usually iiU wings liaAe a discal lunule, though this is 

 often absent on the i)rimaries and not infrequently on the secondaries 

 also. All wings also with an extra median dark and subterminal pale 

 line, followed by a series of brown terminal lunules. Sometimes all 

 this disapi)ears, but more usually the tendency is to obsolescence on 

 the primaries only, and rarely, in dark specimens, both the lines will 

 be pale. 



Expanse of wings, -0 to 24 mm. =0.80 to 0.95 inch. 



Habitat. — Canada to Louisiana and Texas; Middle, (-eiitral, and 

 Southern States; Missouri in August; Canada in June; New York in 

 May; J)istrict of Columbia in August. 



This rather common species is (piite readily recognized by the 

 peculiar color alone. This is a mixture of a pale clay yellow ground 

 overlaid by a darker, more olivaceous yellow brown, and of this the 

 markings consist. The prominent, rigid transverse anterior line and 

 the equally ])romiiient upright rigid shade in the subterminal space 

 distinguish the species at a glance, even though it varies greatly iu 

 the depth of its ground to an almost smoky purplish gray. Fresh 

 specimens are quite handsome.

Head moderate, not prominent, without distinct frontal tuft. Eyes 

 large, not prominent, naked. Ocelli distinct, smaller in the male, close 

 to the compound eye, ami rather near the base of the anteniue. Tongue 

 moderate iu length, strong. Palpi long, compressed, curved ui)ward, 

 and sometimes rising nearly ui)right, but not recurved. Vestiture not 

 long, so the joints are not broad as seen from the side; the terminal 

 joint or its vestiture truncate at tip. There is no notable difference 

 between the sexes. Antenna' moderate in length, scarcely exceeding 

 half that of the primaries; simple iu the female, in the male with mod- 

 erate lateral bristles, and interiorly the joints have shorter fine hair, 

 arising from small tubercles. The body is small, the abdomen slender, 

 cylindrical, reaching to or somewhat exceeding anal angle of seconda- 

 ries. Legs moderately long and stout, tibite with long unequal spurs 

 as usual, the anterior pair modified in the male. The tibia is short, 

 with a narrow, long, membranous anterior process, not e(pialing in 

 length the basal joint of the tarsi, and without special modified scales, 

 tufts, or pencils of hair. Wings moderate, primaries rather elongate 

 and narrowed, differing in the sexes.
