Head and thorax fawn brown, often with an olivaceous tint; palpi reddish 

 l)eneath ; a hiteral whitish line often iucliniug to roseate, on head and thorax, 

 patagise edged above with ferruginous brown. Abdomen with a broad, dorsal 

 dusky baud, containing five somewhat indefinite darker lines and a rusty yellow 

 lateral band still less distinctly strigate. Primaries light brownish yellow, some- 

 times rich yellowish brown, somewhat purplish at the base, a dark smoky brown 

 patch below the origin of vein 1. From the apex a series of from seven to nine 

 darker brown, rather straight lines diverge tow'ard the inner margin ; a brown 

 shade accompanies the inner lines, reaching the hind margin rather close to base ; 

 a yellowish shade from the extreme apex to the middle of the inner margin, 

 broadening toward that point. The outer lines are rigidly parallel with the 

 outer margin. A small blackish discal dot. Secondaries black, outwardly mar- 

 gined with brown; costal margin and anal angle yellow, and with a series 

 of large wedge-shaped yellow subtermiual spots. Beneath, disc purplish, out- 

 wardly ochreoiis with ferruginous powderings; an indistinct, interrupted oblique 

 transverse line ; a row of black venular dots, outer margin purplish ; secondaries 

 ochreous with ferruginous powderings; two purplish transverse bands; a row of 

 blackish venular dots, not reaching the inner margin; outer margin ])urplish. 

 Legs grayish. .\b;lomeu with a series of small black stigniatal dots. Expands 

 from '2.-25— 3 inches ; 56 — 75 mm. 



Hah. — Canada to Massachusetts occasional, southward to Texas, 

 West Indies, Central and South America ; westward to Iowa. 



The most elegant and graceful of our species, varying only in the 

 ground color. Its home is South and West, where it is common, but 

 it I'anges northwardly as far as Canada as an occasional visitant. 



The larva was figured by Abbot, and subsequent authoi-s have, 

 apparently copied this figure and drawn their descriptions from it.

The differences between this genus and Philampelm are largely 

 comparative, yet evident. The head is larger, more prominent ; the 

 eyes larger ; antennaj more slender, and with a short hook at tip. 

 The thorax is further advanced before the base of primaries, and the 

 abdomen is larger and more slender. The wings, too, are somewhat 

 more narrow, the secondaries with anal angle prominent, and as a 

 whole the species are more graceful than in the other genus. The 

 single species is hardly a native of the United States, though it often
