Head and thorax rich chocolate brown ; palpi paler ; a dorsal stripe on thorax 

 paler. Abdomen sometimes darker, usually paler, with a dusky dorsal litie, 

 .sometimes with irregular tawuy spots; segments sometimes indistinctly paler 

 ringed. Primaries chocolate brown; basal space paler, with a dusting of lilac 

 scales, crossed by two darker rather indistinct wavy lines. A very oblique, dis- 

 tinct brown shade line from basal third of costa to hind margin somewhat beyond 

 the middle, where it joins an elongate purplish blotch resting on the hind mar- 

 gin and extending nearly to the anal angle. A series of undulated dark and 

 lilac transverse lines at outer fourth of wing; a yellowish ante-apical costal 

 patch, and another of the same color before anal angle. Through the tei-miual 

 space extends a lilac shade line angulated or dentate opposite the apex. A series 

 of dai-ker interspaceal longitudinal shades in the outer portion of wing most 

 marked opposite the cell and elsewhere often obsolete. A small, brown discal 

 spot. Secondaries: disc dull yellow, costal region and outer margin to middle 

 chocolate brown ; a yellow patch at apex. Ocellus black, with a large i)lue pupil. 

 Beueath, primaries rusty reddish brown basally, outwardly darker, with the 

 maculation of primaries distinctly reproduced. Secondaries reddish yellow 

 brown crossed by a series of pale blue undulated Hues, outer margin broadly 

 brown to the middle. Thorax and abdomen beneath powdered with pale lilue. 

 Expands 2 — 2.5 inches; 50 — 62 mm. 



Hab. — Canada to Georgia ; westward to the Mississi|)j)i. 



The corneous process of the % genitalia is rather hirge and hroad, 

 the tip produced at tlie u|)per angle into a short beak. 



The species is rare usually, though not difficult to rai.se it' one seeks 

 the larva. There is little variation in the si)ecies so far as it has 

 come under my notice, except in depth of ground color and distinct- 

 ness of maculation. From its nearest ally, astylus, it is easily sepa- 

 rated by the darker color and more complete maculation. The larva 

 has been often figured and described, but we have no com])lete life 

 history, and the descriptions vary so greatly as to indicate extreme 

 inconstancv in color.
