Lepidoptera of New York and Neighboring States 599 



line is. Sometimes with a broad brown ray in the silver streak. Hind wing 

 white, or cream with a white fringe. 18 mm. 



This species is usually found in peat-bogs. 



Quebec to Massachusetts, New York, and northern New Jersey. New York: 

 Niagara Falls. 



7. C. youngellus Kearfott. Closely similar to G. bidens, but smaller; brown 

 costal edge slightly wider, ground yellow and somewhat dusted with light brown; 

 a silver postmedian patch and a silver stripe on inner margin; terminal line stop- 

 ping above middle of wing, and dots only below; more or less silver along the 

 veins. Apical markings as in the preceding group; the terminal line and white 

 streak in the fringe not ending abruptly as in C. -floridus. Subterminal line 

 broader than in C. alboclavellus. 18 mm. 



Mer Bleue, Ottawa, Ontario. 



American records of C. hamellus appear to belong in part to this species. 



8. C. prasfectellus Zincken. Chocolate brown; inner margin hardly paler. Silver 

 streak covering cell, and extending well beyond it, but not reaching the sub- 

 terminal line, and separated from the costa by half its width; a slight silver 

 streak above its apex, but the veins on the disc hardly, or not at all, marked 

 with silver; subterminal line silvery, as usual; moderately bent opposite cell, 

 but little widened at the costa. Terminal space brown, with silver triangles above 

 and below an oblique apical dash; a few white scales in lower part of wing, but 

 no spot. Terminal line brown, hardly darker; dots below oval, and set well back 

 from margin. Fringe shining brown-gray, becoming white in its base, toward the 

 apex. Hind wing cream white. 2 mm. 



Two broods, flying mainly in June and August; common. New York. Common 

 everywhere. 



Generally distributed. 



Hardly distinct from G. leachellus. In the Colorado race, oslarellus Haimbach, 

 the hind wing is dark. 



9. C. leachellus Zincken. Like C. prcefectellus, but with the costal edge only 

 very narrowly brown toward the base; apex normally slightly more acute; region 

 beyond tip of silver streak distinctly yellow. Frequently larger; expanding up 

 to 27 mm. 



June and July. 



Common and generally distributed, flying with G. prcefectellus. New York: 

 Wilmington, Saranac Lake, Newport, Ithaca, New York City, Yaphank. 



This species is probably the true hastiferellus of Walker, rather than the fol- 

 lowing, which may be a southern race of it. 



10. C. quinquareatus Zeller. Closely similar to G. leachellus, the light area 

 beyond the tip of the silver stripe nearly white, and connecting it with the sub- 

 apical silver triangle, which is a little larger than in G. leachellus. Apex a little 

 more strongly pointed, but terminal line and white streak in fringe not ending 

 abruptly; terminal dots replaced by slender bars nearly as long as those of 

 C. laqueatellus, on a fuscous ground. No silver line above the tip of the streak 

 in cell, (extorralis Hulst; hastiferellus auct.,' not Walker.) 



Southern States, north to Pennsylvania; northern distribution uncertain on 

 account of confusion with C. leachellus (hastiferellus Walker.) 



11. unistriatellus Packard. Chocolate brown; a broad silver white stripe from 

 base to costal half of outer margin, leaving a brown costal stripe which is 

 extremely narrow at the base and apex, but reaches down to the cell between, 

 and is widest at three-fourths way out. Terminal line and dots very weak; 

 costal half of fringe white. 25 mm. (exesus Grote. ) 



Apparently rare. 



Labrador to Pennsylvania; west to California. New York: Saranac Inn, North 

 Creek, Newport, Trenton Falls, Schenectady.
