Head and thorax light fawn color ; top of frontal crest and a broad dorsal band 

 of thorax chestnut brown ; vestiture white-tipped at base. Abdomen usually 

 somewhat darker, often concolorous with thorax, with dusky dorsal and lateral 

 lines, the latter sometimes wanting; often a series of obscure paler si)ots on each 

 side of the middle. Beneath, as a whole, paler, more reddish. Primaries light 

 fawn at base, darker beyond the oblique shade. Basal space crossed by one or 

 two darker wavy lines, which are sometimes wanting. A broad shade l)and ex- 

 tends obliquely from costa at basal fourth to the internal margin near the hind 

 angle, where it is marked by three black spots. This shade is widest on the disc. 

 At outer fourth there is a sinuate broad pale shade, in which are three narrow 

 darker lines: a distinct brown discal spot; a pale subterminal transverse shade 

 dentated opposite the apex. The excised part of the scallops of external nuirgin 

 is white; usually the specimens are veiy distinctly marked; rarely the macula- 

 tion is suffused. Secondaries with rosy red, the costal region darker; a large 

 black ocellus near anal angle with a round blue pupil ; the fringes also white 

 tipped. Beneath, primaries rosy red on disc, outwardly darker, with the macu- 

 lation of primaries reproduced. Secondaries pale fawn, tinged with rosy red at 

 base, with a broad paler median band, in which are three somewhat irregular 

 dusky lines. Expands 2.5 — 3.75 inches; 63 — 93 mm. 



Decidedly variable in size and ground color ; sometimes the males 

 are much darker with an olivaceous shade, more or less tinged with 

 purple. The coi-neous process of the male side piece is broad, I'ounded 

 at tij), emarginate superiorly before tip, the upper edge of the emar- 

 ginartion serrate. Sometimes vein 9 of the primaries forks near the 

 apex and then the full number of 12 veins is present. This, how- 

 ever, seems rather rare. 



The species is distributed thi-oughout the Eastern United States 

 and Canada, and is perhaps the most common of the Eastern Smer- 

 inthince ; there are two annual broods.
