LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 625 



2. Markings very clean-cut; extreme base blackish, with a red shade before 



the antemedial line 1 . turpidella. 



2. Whole basal area reddish 0. vctustclla. 



2. Base mostly light gray, reddish at basal angle 5. contatella. 



1. Antemedial line not followed by a pale patch on inner margin. 

 2. Base distinctly paler. 

 3. Base yellow or reddish. 



4. Followed by a strong antemedial line, outer part blue-gray. 



5. Costa and inner margin broadly brown 11. cviatella. 



5. Outer two-thirds entirely gray 10. ba&ilaris. 



4. Antemedial line obscure, 



5. Base mostly yellowish 8. lavigatetta. 



5. Base yellowish toward inner margin only 7. celtidella. 



3. Base lighter gray without any yellow or brown. 



4. Antemedial space blackish 9. semiobscurella. 



4. A double black antemedial line toward inner margin only. 



13. purpurella. 

 2. Base not paler than outer part of wing. 



3. Antemedial region, and dark shades defining the postmedial line, strongly 



shaded with crimson 12. cameella. 



3. At most, with crimson streaks between the veins. 



4. Pale antemedial line strongly waved on fold and on A 5. contatella. 



4. Antemedial line almost straight on lower half of wing 4. afflictella. 



1. S. turpidella Ragonot. Powdery gray, the lines hardly paler, sharply edged 

 on both sides with black; the first line zigzag, normal, the second normal, rather 

 more irregular than usual. Discal bar continuous, black; a blackish median shade 

 below it toward inner margin; terminal line continuous, black; a slight brownish 

 shade in the fold before the antemedial line. 18 mm. 



Massachusetts and Colorado. 



Distinguished from all other species in the genus by its absolutely clean-cut 

 markings. 



2. S. annulosella Ragonot. Mid-tibia blackish with a contrasting pale tip, basal 

 segments of abdomen transversely banded with black. Scale tuft on antenna twice 

 as long as scape. Fore wing light gray, with blackish shades beyond the antemedial 

 line at costa, before it at inner margin, over costal end of postmedial line, and 

 sometimes covering most of the base; antemedial line obscurely paler; postmedial 

 faint, normal, preceded by a slight darker shade. Discal dots separate, black, 

 contrasting; terminal dots separate. 18 mm. 



The pale patch beyond the antemedial line is often obsolete in light specimens, 

 but the species differs from afflictella, in the nearly obsolete, diffuse, antemedial 

 line, and the much fainter postmedial. 



Massachusetts to Texas and Colorado. 



Northern records are possibly in error for S. engeli. The form with the base 

 shaded with brown is variety pumilella Ragonot: the type form has a blackish 

 base, while those with concolorous base are variety nubiferella Ragonot. 



3. S. engeli Dyar. Abdomen not banded with black. Dark fuscous, the markings 

 more or less obsolescent, except for a large whitish dorsal patch over and beyond* 

 the antemedial line, sometimes continued across to the costa. Some pale scaling 

 about the discal dots. Postmedial line traceable, pale. Tuft on antenna hardly 

 larger than scape. 18 mm. (annulosella, in part). 



May to July. 



Xew Jersey to Texas. 



4. S. afflictella Hulst. Base fuscous, out almost to the middle of the wing; 

 crossed by a strong whitish basal line; antemedial line whitish, fine, a little waved,
