with whitish scales ; tarsi cinereous, first two segments whitish 

 interiorly ; posterior tibiae cream color, brownish just before the 

 spurs. 



Fore wings creamy white along the hind margin, on the costa 

 cinnamon brown; costal triangular spot cinnamon brown, bor- 

 dered outwardly above the fissure by a broad white line ; below 

 the fissure its apex is continuous with the brownish color of the 

 second lobe. Both lobes cinnamon brown, with a transverse white 

 line not reaching the hind margin of the second lobe. Fringes 

 cream color, sprinkled with cinnamon brown. Hind wings cinna- 

 mon brown, with fringes concolorous. 



Habitat. Nevada. Early stages and food plant unknown.

Expanse of wings, 16-20 mm. Head, palpi and frontal tuft 

 grayish brown. Antennae whitish, dotted above with dark brown. 

 Thorax gray in front, white behind. 



Fore wings whitish, heavily dusted with brownish gray. The 

 somewhat indistinct brownish triangle on the outer third of the 

 costa is followed by a whitish spot, and a subterminal white line 

 crosses both lobes. 



Habitat. Europe, Massachusetts. Food, Gnaphalium dio- 

 icum, G. arenarium. 



4 'The egg is pale green, smooth and somewhat elongated, and 

 the larva in its earliest stage is clear white with isolated hairs. 

 Head, thoracic and anal shields black. Later (in September) the 

 dorsal and lateral rows of rust-brown points appear, and in March, 

 after hibernating, it becomes stout without increasing very much 

 in length. The head, thoracic and anal shields are dark brown ; 

 dorsal stripe is crimson rust color ; the subdorsal and lateral lines 

 are of the same color but finer. The ground color of the body is 

 yellowish above and rust red beneath. The adult larva is a little 

 smaller at each end and cylindrical in the middle. The head is 

 small and black, the thoracic shields small, black divided by a 

 light line. The color of the body is dark ferruginous brown. On 

 the back stand whitish flecks with two pairs of black tubercles on 

 each segment, of which the hinder are placed farther from each 

 other than those in front; similar tubercles occur on the sides, 

 from which arise long light hairs. The anal shield and legs are 

 dark brown. These larvae frequently vary in the tone of the 

 color." (Gartner.)
