(Lepidoptera, Coleophoridcs) 



By CARL HEINRICH 



The two following species were reared by the writer in con-

 Bureau of Entomology, at the eastern station. 



Coleophora lentella, new species. 



Palpi yellowish, slender ; third joint little more than half as 

 long as second; very slight tuft on second joint. Antennag 

 whitish yellow, annulated with light golden brown; basal joint 

 tufted above with pale ochreous scales. Face, head and thorax, 

 pale ochreous. Forewings light golden brown, shading to darker 

 brown in apical portion, with white costal streak from base to 

 costo-apical cilia; cilia golden brown. Hindwings brownish 

 gray; cilia very light golden brown. Underside of fore and 

 hind wings lead colored. Legs ochreous, dusted with dark 

 brown on outer sides ; tarsi faintly annulated with light brown. 

 Anal tuft light ochreous. Alar expanse, 8 mm. 



Habitat: Great Neck, Long Island. 



Food Plant: Betula lenta (Sweet-birch). 



Type, Cat. No. 19897, U. S. Nat. Mus. 



Described from moth reared June 22, 1915, from larva 

 mining leaves of "sweet birch." This species is nearest to C. 

 alniella Heinrich and belongs to the carycBfoliella group. 



The larval case is quite characteristic, being shorter and 

 broader in proportion than that of any other species in this 

 group. It is light brown, smooth; 4}^ to 5 mm. long by 1^^ 

 mm. wide; a slightly flattened cylinder in form, the posterior 

 end not so wide as middle of case and flattened to a straight 

 edge ; mouth deflected to 45 degrees. 



Coleophora gaylussaciella, new species. 



Palpi creamy white, slender; third joint as long as second; 

 second joint but slightly tufted. Antennae white, annulated 

 with light brown ; conspicuous tuft of creamy white scales 

 above basal joint. Face, head, and thorax creamy white. 

 Forewings light buff shading to white at extreme base; apex
