black lines across it. Terminal line black on costal half of wing, preceded 

 with silver, subterminal line also silvery. 23 mm. 



Common and generally distributed, in June. Larva on moss; refusing grass, 

 at least when young. New York: common everywhere. 



2. C. myellus Hiibner. Chocolate brown, shading into ochre yellow at mar- 

 gins; three silver-white patches in middle of wing, separated by brown fasciae, 

 the first running to the middle of the wing, obliquely triangular, the second 

 half as long and rather trapezoidal, the third a narrow subterminal bar. Ter- 

 minal line obscure, continuous; fringe gray, cut with white opposite the cell. 

 22 mm. (luctuellus Fernald, not Herrich-Schaeffer ) . 



July. Caterpillar under moss; brown, with black head and cervical shield. 

 Labrador to Carbondale, Pennsylvania, and west to British Columbia. New 

 York : Karner. 



3. C. agitatellus Clemens. Fore wing broader than that of C. laqueatellus, of 

 the same pale yellow, becoming darker along the markings, and nearly white on 

 the inner margin. Silver streaks broader and separated only by the fine, often in- 

 complete line along R; the longer streak less than three-fourths of the length 

 of the wing. Middle of wing silver white from cell to outer margin, cut by the 

 silver and yellow subterminal line. Apical marks as in laqueatellus; terminal 

 line fine and bla<-k on costal third, replaced by five thick dots along outer margin 

 below; base of fringe silver white toward costa, the rest silver gray. Hind wing 

 cream white, lightly shaded with gray. 20 mm. (saltuellus Zeller.) 



Generally distri-buted and common, especially northward; flying mostly in July. 

 New York: North Elba, Summit of Mt. Marcy, Newcomb, North Creek, Rock 

 City (Cattaraugus County), Ithaca, Trenton Falls, Scheneotady, New Windsor, 

 Crugers; Lynbrook, Long Island. 



4. C. alboclavellus Zeller. Identical with C. agitatellus except for the lack of 

 the brown line on R, probably a variety of it. Ground color usually a little 

 darker, and sometimes a little shaded with dark brown; trapezoidal patch beyond 

 the silver streak usually brighter silver and standing out more distinctly (cam. 

 linellus Haimbach ) . 



July and August. Larva on grass. 



Common and generally distributed. New York: Newport, Nevvomb, Lewiston, 

 Potter Swamp (Yates County), Ithaca, Big Indian Valley, Utica, Schenectady, 

 New Windsor, Fort Montgomery, Katonah. 



5. C. labradoriensis Christoph. Dark brown, diffusely shaded with whitish, 

 especially opposite the cell, over M, to CUj, and ih areas extending to the inner 

 margin before and on the middle of the wing; a silver bar in the cell, broad 

 outwardly, but hardly reaching beyond middle of wing, separated from the whitish 

 area beyond by a broad zigzag median band, the tip of the silver streak forming 

 two teeth, the lower of which is only a little smaller than the upper; costa 

 broadly brown; subterminal line normally silvery, a little enlarged at costa. A 

 triangle before and one beyond it at costa. A terminal line above, and dots below, 

 preceded narrowly with white. Hind wing fuscous. 20 mm. (luctuellus auct., 

 not Herrich-Schaeffer.) 



This species may prove to be a race of C. luctiferellus, of Europe, which has 

 Sc and R\ anastomosing. I have not examined the venation. C. dissectus Grote 

 appears to be the same, both names applying to light forms. 



New York (type of dissectus) and Mer Bleue, Ontario, to Oregon, and north. 



6. C. bidens Zeller. Similar to C. alboclavellus and C. agitatellus; silver streak 

 three-fifths length of wing, its tip bluntly angled, reaching costa, leaving only a 

 fine brown costal edge, and strongly toothed below, at origin of Cu 2 . Ground 

 brownish ochre; no silver patch in middle of wing beyond cell; but middle of 

 terminal space white; black terminal line extending below middle of wing; the 

 dots somewhat elongate and distinctly farther from the margin than the terminal
