The species reminds much of the genus Recurvaria from which 

 Eucordylia is a derivative. 



Recurvaria alnifructella n. sp. 



Second joint of labial palpi dark fuscous with apex white; terminal 

 joint white with two broad black annulations, one near the base and one 

 just before the tip. Face and head ochreous white. Antennae light fus- 

 cous with narrow black annulations. Thorax ochreous white, slightly 

 sprinkled with fuscous and with two minute black dots at the base of the 

 hindwings. Forewings black with white dorsal edge; an indistinct white, 

 outwardly curved costal streak at apical fourth and an opposite oblique 

 dorsal white streak limit an apical area, which is slightly mottled with 

 lighter scales; three small black tufts of raised scales on the border of the 

 white dorsal part; cilia ochreous fuscous. Hindwings silvery fuscous, 

 semitransparent; in the male with a long ochreous expansible hairpencil 

 at base; cilia ochreous. Abdomen dark fuscous with light ochreous anal 

 tuft and with an ochreous patch on the upper side of the first joints. Legs 

 black with ochreous white annulations at the end of all the joints. Alar 

 expanse; 12 mm. 



Habitat: Falls Church, Va., Carl Heinrich, collector. 



Type: Cat. No. 19226, U. S. N. M. 



The larva feeds in the catkins of alder and hazel in the same 

 fashion as Eucosma walkerana Kearfott, the larva of which is 

 described by Packard in his "Forest Insects" p. 636, misidentified 

 as Gelechia coryliella Chambers (Menesta tortriciformella Clemens).. 



The full grown larva of the present species is about 12 mm. 

 long with a light brown head, dark brown thoracic shield and 

 anal plate; small brown tubercles, arranged in a transverse row 

 on each segment; body is white with a broad pink annulation in 

 each joint; thoracic legs light brown; abdominal prolegs with a 

 circlet of hooks, which is broken on each side, interiorly and 

 exteriorly. 



Gnorimoschema gibsoniella n. sp. 



Labial palpi white dusted with blackish 1 rown scales; ;n ill-defined 

 b ackish annulation on the middle of terminal joint. Face and head white 

 speckled with blackish brown. Thorax white strongly dusted with black- 

 ish brown. Forewings with a bluish white ground color, so strongly suf- 

 fused with brown and blackish scales, as to make it difficult to determine 

 what is the ground color; each white scale has a dark band before the tip; 

 three ill-defined brown spots, one on the middle of the cell, one obliquely 

 below on the fold and one at the end of the cell; basal part and dorsal edge 

 of the wing least suffused with dark scales so as to slightly outline the 

 pattern found in the type of the genus; cilia white strongly dusted with 

 black and brown. Hindwings light fuscous with still lighter cilia. Abdo-
