(8) C. concolorella Clemens. 



Alar expanse: 10 mm. 

 Locality : Pennsylvania ( June ) . 

 Food plant: Unknown. 

 Larval case : Unknown. 

 A pale mauve species near cinerella Chambers but apparently distinct. 



(9) C. cinerella Chambers. 



Alar expanse: 10 mm. 



Localities: Kentucky; District of Columbia. (End of May to July). 



Food plants : Birch and alder. 



Larval case: Similar to that of pruniella Clemens; dark rusty brown; 

 roughly cylindrical with a couple of serrate projections 

 on outer side; mouth deflected to 45 degrees; posterior end 

 rounded and flatly compressed. 



II. Entire insect of a shining metallic luster; unicolorous, larval case with 

 apex triangularly compressed. Larvce leaf miners on low plants. 



(10) C. aenusella Chambers. 



Alar expanse: 11 mm. 



Locality : Kentucky. 



Food plant: Unknown. 



Larval case: Unknown. 



Known only by Chambers' description. Easily recognized, however, being the 

 only metallic bronzy species in the eastern United States with simple antenna 

 thickened at basal joint only. 



(11) C. coruscipennella Clemens. 



Alar expanse: 11-12 mm. 



Locality: United States ( May- August ). 



Food plant: Unknown. 



Larval case: Unknown. 



A very common species, found nearly everywhere in the United States. Has 

 been frequently identified as the European spissicornis Haw. (fabriciella Vill. ). 

 C. auropurpurella Chambers is a synonym. 



(12) C. apicialbella Braun (apicella Braun). 

 Alar expanse: 9.511 mm. 



Locality: Cincinnati, Ohio, (late May and early June). 



Food plant: Silene virginica. 



Larval case: Gray, darker on dorsal surface; cylindrical; mouth slightly 



deflected; 7-9 mm. long. 



Easily distinguished from other species of this group by the antennae. These are 

 clothed with rough, purplish scales for basal four-fifths, the apical fifth being 

 silvery white without annulations but with a black dot on underside of each 

 segment. 



III. Moths with fore wings golden to dark brown; costa white, otherwise 

 unmarked; antenna thickened with scales near base, with very slight tuft on 

 basal joint. Larval cases cylindrical and with apices flatly compressed (The so- 

 oalled "cigar-case" type fig. 121b). Larvce leaf miners, mostly on trees and 

 shrubs. 



(13) C. rosacella Clemens. 



Alar expanse: 10.5 mm. 



Locality: Pennsylvania (late May and early June). 



Food plants: Rose and sweet briar. 



Larval case: Brown; smooth except for one or more serrations on upper 



edge; mouth deflected (from Clemens' description). 



The darkest of the brown Coleophoras with white costal markings on the fore 

 wing.
