the Bureau of Entomology. The writer is indebted to .Mr. Busrk 

 for final determination of the species. 



Coleophora leucochrysella Clemens. Dyar X. A. Lp. No. 6026. 



Eleven* specimens of this beautiful moth \vere reared under 

 Hopkins U. S. No. 11135. 



Larval case 10 to 11 mm. long; first two-thirds made from material nf 

 the leaf; light yellow; elongate cylindrical, somewhat flattened and slightly 

 bulged in the middle with distinct fin-like projection from base to middle; 

 mouth deflected about 30 degrees; posterior third made of pure silk, slightly 

 darker, curving in to a blunt point and splitting vertically along the ]><>-- 

 terior extremity of the keel. 



Habitat: Falls Church, Virginia, and Charter Oak, Pennsylvania. 



Foodplant: Castanea dentata 



The larva mines the leaves from the under surface. The clear, 

 rectangular mine with the small circular entrance on the under 

 side clearly distinguishes the work of the species. A number of 

 full grown larvae collected at Falls Church, Virginia, during the 

 early part of May, by Mr. Busck and the writer, pupated June 2, 

 the adult moths issuing June 16 to 20. The larvae overwinter in 

 the cases, which are attached to the twigs or the bark of the tree, 

 and feed up during the following May. 



Two new species of Hymenopterous parasites of the larvae 

 (Microdus sp. and Microbracon sp., determined by Mr. S. A. 

 Rohwer) were reared from larvae collected at Falls Church, and 

 from a couple of larvae collected at Charter Oak, Pennsylvania, 

 by Mr. T. E. Snyder, of the Bureau of Entomology.
