Some of the following species may be valid, or all may be food-varieties of 

 splendoriferella. Besides these species, larvae of the genus have been found on 

 several other food plants, but not distinctively named. 



2. C. lucifluella Clemens. Larva on hickory. Moth slightly grayer than splen- 

 doriferella, the golden area toward apex forming a broad band on costal third 

 only; rest of ground of outer half solidly dark brown; the gray basal portion 

 somewhat less extensive, and the markings generally not quite so far out. 



Cocoons may be found on the trunk under loose bark. 



3. C. ostrygefoliella Clemens. Larva on iron-wood (Ostrya) ; the mine larger 

 than usual in the genus, and the case comparatively small. 



The moth looks like a somewhat more richly colored splendoriferella, with some- 

 what more extended golden area. 



4. C. saliciella Clemens. Larva on willow. Practically indentical with splen- 

 doriferella but with the brown patch less sharply set off from the yellow; with two 

 full rows of yellow scales between it and the black apical spot. 



Missouri ; Washington. . 



5. C. diospyriella Chambers. Larva on persimmon. Moth markedly variable, 

 being either more or less yellow than splendoriferella. 



The moth flies in June in Ohio. 



6. C. ella Chambers, from hickory, is probably a strict synonym of lucifluella. 



7. C. juglandiella Chambers. Markings of moth like those of splendoriferella, 

 but larva feeding on black walnut; the case smaller; and the moth appearing 

 earlier. 



8. C. magnella Braun. Larva on Gaylussacia in August, in the usual mine. 

 Moth with the blackish area beyond the dorsal spot reduced, not extending 

 beyond it toward costa, and sometimes practically confined to the fringe. 



9. C. negligens Braun. Head, thorax and basal half of fore wings pale leaden- 

 metallic. Antenna? blackish. Apical half of fore wing bright ora-w^e-yellow, 

 more orange than any other species of the genus. Black and silvery apical mark- 

 ings essentially as in C. splendoriferella. 



Larva mining cranberry in May; working in the overwintering leaves. Moth 

 in June. One brood; apparently hibernating in the egg stage. 

 Buckeye Lake, Ohio. 

 Another rather distinct form occurs on white oak.
