suggestion of oblique dark shades over end of cell, and opposite it at anal angle. 

 Fringe concolorous; hind wing slightly paler. 30 mm. 



September.

14. E. fulminana Walsingham. Deep dull brown, practically the same shade as 

 in E. sombreana and mandana; more or less, though usually only slightly, mottled 

 in two shades; often with an area of narrowly white-tipped scales below and 

 beyond the end of the cell, and some scattered white scales. Costa with geminate 

 paler striae, becoming distinctly whitish toward the apex; the last one nearly 

 1 mm. back from the apex. Speculum composed of two broad, vague, irregular, 

 lead-gray bars, the outer one normally broken in two, with, as a rule, some black 

 scales between them. Hind wing mouse gray. 27 mm. 



Late July. 



Illinois and Wisconsin to Texas. 



15. E. rusticana Kearfott. Fore wing luteous on dorsal half and toward outer 

 margin, including apex; shading into blackish on costa, except at the apex; the 

 darker parts more or less streaked with black. Speculum a vague, paler, and 

 grayer area, with a couple of long black streaks. Fringe luteous and light brown. 



June; August. 



North Carolina to Illinois and south. 



16. E. sombreana Kearfott. Dull gray-brown, mottled faintly, and becoming a 

 little warmer brown toward the outer margin; with geminate pale costal stria?; 

 base slightly darker, with oblique outer boundary; a lead-colored line along outer 

 margin, nearly meeting a shorter one at anal angle; with some black scales in 

 the space between, but no definite speculum. Fringe powdery. 16—22 mm. 



July and August. Larva in Helianthus. 



New York to Manitoba, North Carolina, and Arkansas. New York: Ithaca, 

 Brooklyn. 



17. E. albiguttana Zeller. Pale ochreous, with scattered silvery gray spots of 

 a few scales each; costa obliquely striate with whitish, the outer striae lightly 

 edged with black; speculum of two vertical silver bars, connected by three con- 

 trasting fine black streaks. Base of fringe dusted, black and white. Hind win£ 

 very pale gray. 12 mm. {ochraceana Fernald).

18. E; graciliana Kearfott. Doubtfully distinct from E. albiguttana; ground 

 brighter cchre yellow; silver spots clean-cut and sharply gray-edged, as well as 

 the strise on the costa; one stria from the costa reaching practically to the outer

19. E. cataclystiana Walker. M 3 and Cu\ of fore wing becoming coincident at 

 margin. Fore wing dull ochre, somewhat mottled, or more rarely, yellow -brown; 

 costal strise pale, somewhat silvery, distinctly defined with dark, the last one 

 running along the outer margin, which is drawn out and subfalcate, about as in 

 the lowest species of Ahcylis. First silver bar of speculum slightly oblique, 

 preceded by a brown shade and followed by two strong black dots; outer bar short, 

 marginal. Base of fringe powdered, black and white. 16 mm. 



Aberrant specimens have a brown ground color and the area above the speculum 

 crisply dusted with white. In western specimens, the anterior bar of the speculum 

 is more oblique.
