cell. Costa outwardly with paired lino white striae; the ground toward apex 

 shaded with yellow-brown. Speculum silver and cream-white, with some black 

 scales; preceded by a region striate with black, and followed by a black bar; 

 fringe light; the basal series of scales narrowly black-tipped, but "hardly forming 

 a line. Hind wing mouse gray, paler at base between veins. 13 mm. 



August. Type only seen. The veins in the fore wing are distinctly approxi- 

 mate at the margin, which is concave. 



Kennebunkport, Maine. 



15. E. obfuscana Dyar. Base gray, transversely striate with blackish, its outer 

 boundary about one-third way out, erect, and very slightly excurved; somewhat 

 diffuse. Outer part of wing white, striate with light gray, slightly more densely 

 in the postmedial region. A black apical dot, and terminal bar at middle of outer 

 margin; fringe dull black, whitish at anal angle. Hind wing dark gray. 16 mm. 

 (obfuscata Riley, undescribed). 



May to September. Larva in Solidago. 



General in distribution. New York: Rock City (Cattaraugus County), Ithaca; 

 Clove Valley, Staten Island. 



16. E. illotana Walsingham. Wings broader than in scudderiana. Base black- 

 ish, mottled with dull black on blue-gray ; outer part nearly white, the boundary 

 diffuse and farther out on costa; wing shaded with light gray toward apex, and 

 before anal angle; speculum represented by two or three black dots before outer 

 margin; fringe gray on costal half. Hind wing nearly white. 15 mm. 



May and June. 



Probably generally distributed. New York : Kinderhook. 



17. E. desertana Zeller. Basal third of fore wing blackish; strigose; with 

 waved, erect, outer boundary; rest of wing white, with some gray striae, gathering 

 to form a distinct gray and black triangular patch before the speculum, which 

 is a mere silvery patch, with an oblique gray line bounding it above, resting on 

 the outer margin. Terminal line and fringe blackish except at anal angle. Hind 

 wing gray. 15-20 mm. 



Larva in Solidago. Moth at end of May. 



New York and District of Columbia to Texas. New York: Peru, Ithaca, New 

 Windsor, Ramapo. 



18. E. suffusana Zeller. Hind wing with a deep fold on upper side, below 3d A; 

 a thickening between it and the inner deep margin, containing a hairy pencil aris- 

 ing near the base of the wing. Base, a postmedial patch toward anal angle, and 

 apex dull gray; the medial area and speculum white, rather heavily shaded with 

 light blue-gray, more heavily than in Eucosma scudderiana; costal edge dark gray 

 with double white striae on outer two- thirds; some small black dots in speculum, 

 and a transverse series of stronger ones just before it; fringe gray toward apex, 

 white below; hind wing mouse gray. 16 mm. (Notocelia Hiibner). 



European specimens usually show considerable brown shading toward the apex 

 and before the speculum, but more rarely are quite like the American strain, which 

 is probably introduced. 



June. Larva a bud-worm on rose (fig. 278). 



Maine; northern New Jersey, Maryland; Pennsylvania; Europe. 



14. EUCOSMA Hiibner 



(With Pcedisca, Steganoptycha, Halonota, Spilonota,, etc., in part; 

 Euryptychia; Monosphragis Clemens, etc.) 



Palpi somewhat rough and beaklike (fig. 280) ; head rougher than in Las- 

 peyresia and Hemimene, normal. Thorax smooth or tufted. Hind tibiee with 

 a moderate amount of loose hair only. Fore wing normally rather long
