'D. C., August 10; Nebraska, West Point, in May; Northern, Eastern 
‘Middle and Central States. — 
. This is the most common of our eastern species, and it is either double 
brooded or the hibernating imago flies for a long period. Dr. Lintner 
reports the larva on Solidago September 1 and 24. 
A long series of specimens, largely from the collection of the U.S. 
‘National Museum, is before me, and shows little variation. The costa 
‘js sometimes alittle darker, the yellow shading sometimes more intense, 
‘the ordinary spots occasionally a little more marked; but otherwise 
‘there are no noteworthy differences. The secondaries are whiter and 
more hyaline than in any others of the first series, montana, its nearest 
‘ally in this particular, being quite distinctively different in macula- 
‘tion of primaries. 
The harpes of the male are longer and narrower than in the preced- 
ing species, the tip more oblique and superiorly more produced. In 
type characters it does not differ in the least.

( Head dark brown, palpi paler in front, a black, followed by a pale 
‘line on vertex. Collar deep, somewhat carneous gray, with a black 
‘transverse line near base. Patagize deep bluish ash gray. Dorsum 
/ blackish, with a black-tipped, truncate, posterior tuft. Dorsal tufts of 
; abdomen small, but distinct, dark brown or blackish. Primaries deep 
‘bluish gray, with a carneous tivge, costal region from base to apex suf- 
‘fused with brown, extending inward to the median vein. Median 
i lines vaguely marked on costa; the median tooth of t. a. line fairly evi- 
(dent. TT. p. line pale through the submedian interspace, preceded ‘by 
1 &@ distinct, followed by a less evident black line. It is incurved to vein 
‘one, thence very oblique inwardly to the hind margin. A blackish 
streak extends inward along inner margin, nearly to base. Preceding 
_ the s. t. line in the submedian interspace is a small blackish or brown 
Shade, and following it to the outer margin is a brown shade which 
‘ fills the interspace and extends to the outer margin, superiorly empha- 
| sized by a black streak. A broken series of vague interspaceal dashes 
1 along the course of thes. t. line. A series of black terminal lunules. 
‘ Fringes concolorous or fuscous. A fine black basal streak. Ordinary 
‘spots variably distinct, always traceable, sometimes concolorous, more 
/usually paler. They are defined by a very narrow black line, inside of 
‘ which is sometimes a broad gray annulus; in that case the center is 
‘brown. Secondaries yellowish fuscous, smoky outwardly, darker in the 
female, veins dark marked. Beneath, smoky or blackish, powdery, 
| Somewhat paler at the base of the secondaries.
