Hindwin*. — Light brassy fuscous, cilia gray, underside whitish gray ; under- 

 side forewing bronzy brown somewhat overlaid with white. 



Five specimens, Aweme, Manitoba, May 12 to 25, collected by- 

 Norman Criddle ; ten specimens from A. J. Oslar, Chimney Gulch, 

 Golden, Colo., April 14. 



Type in my collection. 



The venation, shape of wings and structure of palpi agree with 

 figure of Gelechia terrella Hbn. in Meyrick's Hand Book British Lepi- 

 doptera, except that vein 5 of hindwing rises about one third from 

 lower angle of cell and veins 6 and 7 are separate. Mr. Busck 

 regards this species as G. virge lla Thnbg. {longicornis Curt.). I have 

 carefully compared a series of this European species and do not agree 

 with his opinion. 



Coleophora elaeagnisella, new species (PI. Ill, Figs. 7 and 8). 



Expanse 15 to 21 mm. 



Head, thorax and palpi dull white (or white with the least trace of a grayish 

 shade), palpi shaded with gray externally ; antennal brushes white in front, gray 

 behind, twice as long as basal joints; antenna white with broad cinereous annula- 

 tions ; abdomen cinereous ; legs dull white, anterior pair dusted with gray in front, 

 all faintly darker between joints. 



Foreiving. — Dull white, slightly shining, dotted sparsely to heavily with dark 

 brown in horizontal rows, except at extreme base ; the dark dots are more closely 

 spaced in apical third of wing. Nowhere do they congregate into larger spots or lines. 

 The white color extends out to the end of the cilia at extreme apex, and is heavily 

 dotted with dark brown ; below apex cilia is grayish cinereous. 



Hindwing. — Shining grayish fuscous, cilia cinereous. Underside both wings 

 the same. 



Winter case about 3 mm. long, the ends and under surface are dark brown, on 

 the upper surface is a large grayish patch : the case is scimeter-shaped, dorsal edge 

 well rounded, radius about Ioo°, ventral edge with an enlargement in the middle, 

 mouth at an angle of about 45 from the ventral line. It is securely attached by the 

 mouth end only to the bark, sometimes in a fork. 



Mature case, 10-12 mm. long, 2.25 mm. wide, 1.75 mm. thick ; of the same 

 general shape as the winter case but less rounded on the dorsal edge, and the hump 

 on the ventral edge is depressed in the middle. The appearance of the mature case 

 would indicate that it was not entirely new, but that the winter case had been used 

 and enlarged by splitting along the ventral line and broadening it out with gray silk, 

 then adding to the open end as the larva required more room. The old part is 

 blackish brown, middle cinereous gray, outer end dark brown, the additions are 

 added on the same angle as the mouth opening, giving an oblique direction to the 

 ridges. 



Fig. 7 shows maculation of forewing, Fig. 8 the large mature case 

 and the small winter case, all three drawn to same scale.
