nella and C. caryaefoliella are well known. C. ostryae was named 

 from larva and case only, and, as far as I am aware, the imago 

 has not been described. I have a series of fourteen specimens bred 

 on Carpinus and Ostrya, and the moths are indistinguishable from 

 specimens of C. caryaefoliella bred on hickory. There is some 

 variation in the depth of color in the fore wings and in the shading 

 on the tarsal joints, but the limits of variation are about the same 

 as in C. caryaefoliella. The case agrees with the description given 

 by Clemens except that the notch near the hinder end is almost 

 always lacking. Allowing for the difference in texture between 

 the leaves of hickory, iron wood and hornbeam, the cases are sim- 

 ilar enough to belong to the same species. The habits of feeding 

 are identical. In my opinion, C. ostryae should be regarded as a 

 synonym of C. caryaefoliella. It may be that the captured speci- 

 mens taken "a mile away from any hickory trees," from which 

 Chambers described C. rnfolutceUa, were Ostrya-feeders, as the 

 cases are often very common. 



COLEOPHORA UMBRATICA, 11. Sp. 



Antennae with the basal joint brownish ocherous, slightly thick- 

 ened with scales ; antennal stalk whitish, annulate with brown, 

 more distinctly toward the apex. Palpi pale ocherous. 



Thorax and fore wings brownish ocherous, deeper toward the 

 apex, very pale toward the base. Costal margin from the base 

 to the costal cilia whitish, this whitish color shading imperceptibly 

 into the ground color of the wing, especially near the base. Cilia 

 concolorous with the wings, becoming grayer dorsally. Hind wings 

 brownish gray, cilia gray. 



Abdomen brown. Legs brownish ocherous, tibiae clotherl with 

 ocherous or reddish brown hairs. 



Expanse: 9-10 mm. 



Three specimens from larvae feeding on wild red plum, Primus 

 americana Marsh, Cincinnati, O. The earliest case is very small, 

 about 1.4 mm. long, and irregularly curved along its upper edge.
