Type: Cat. No. 18183, U. S. N. M. 



Described from seven specimens reared June 28, to July 12, 

 1913, under Hopkins U. S. No. 11143 from larvae feeding on leaves 

 of Carpinus. There are also three specimens of the same species 

 in the U. S. National Museum, reared by Mr. Busck in 1-901 from 

 the same food plant. 



The larval case is dark brown, smooth; 6 to 7 mm. long and 1 to 

 1.5 mm. wide; cylindrical in form with posterior end flattened and 

 slightly wider than diameter of the case; mouth slightly deflected. 



This species resembles C. carycefoliella Clemens, from which it 

 differs in its smaller size, the dark apical dusting on fore-wings, 

 the generally darker color of wings and cilia and the greater de- 

 flection of the mouth of the larval case. 



Coleophora alniella n. sp. 



Palpi white very faintly tinged with ochreous. Antennae white, annu- 

 lated with golden brown; base slightly thickened with scales, white to 

 ochreous, not erected. Face and head golden ochreous shading to white 

 on sides. Fore-wing nearly a uniform golden brown with white streak along 

 costa from base to costo-apical cilia; cilia shading from white at end of 

 costal streak to golden brown on dorso-apical margin. Hind-wings and 

 cilia steel gray with faint golden tints. Abdomen brown with argentious 

 dustings above and beneath. Legs light golden brown on outer, silvery on 

 inner side; tarsi but faintly annulated. Alar expanse: 8 to 9 mm. 



Habitat: Hyattsville, Maryland. 



Foodplant: Alnus. 



Type: Cat. No. 18184, U. S. N. M. 



Described from three specimens reared June 30 and July 5, 1913, 

 under Hopk. U. S. No. 11139, from larvae feeding on leaves of 

 Alnus. 



The larval case is dark brown, rather rough and fibrous; 6 to 7 

 mm. long by 1.5 mm. wide; a slightly flattened cylinder in form, 

 with posterior end flattened to somewhat curved edge like the 

 blade of an axe; mouth deflected to 90 degrees. 



This species so closely resembles C. carycefoliella Clemens, that 

 it is difficult to separate the two on adult characters. I find 

 quite a little variation in the specimens of the hickory species 

 before me, so that whatever very slight size and color differences 

 there are, offer no sure means of differentiating the species. It 

 seems however, that in this case the differences in the foodplant 

 and larval cases should be sufficient to warrant the erection of a 

 new species. 



The chief structural differences are in the posterior end and 

 mouth of the case. In carycefoliella the posterior end is flattened 

 to a straight line, and the mouth deflects to about 40 degrees.
