Type: Cat. No. 19223, U. S. N. M. 



Reared by Mr. Brunner from Populus trichocapa. The spe- 

 cies is closely allied to the other Populus species, M. dollii Neu- 

 moegen, and castaneum Beutenmuller, but at once distinguished 

 by the clear hind wings. 



Psacaphora cambiella n. sp. 



Second joint of labial palpi reddish golden; terminal joint black. Face, 

 head and thorax shiny iridescent black. Antennae black with silvery white 

 tips. Forewings purplish-black with a large, central, light brick-red part, 

 which occupies about half the wing area; within this red part are three 

 small oval black spots edged with purplish silvery scales ; one of these spots 

 is on the middle of the fold, the other at the end of the cell and the third 

 about the middle of the cell, touching the black costal edge of the wing; 

 at apical fifth is a light yellow costal dash, continuing into the cilia and 

 on the terminal edge is a purplish silvery longitudinal streak within the 

 black border; cilia black. Hindwings and cilia purplish black. Abdomen 

 black. Legs black with golden yellow inner sides and with a golden annu- 

 lation on posterior first tarsal joint. Alar expanse: 13-14 mm. 



Habitat: Evaro, Mont., J. Brunner, Coll. 

 Type: Cat. No. 19224, U. S. N. M. 

 Bred from cambium of Salix. 



Close to P. purpuriella Busck, in coloration, but different in 

 pattern. 



Eucordylea gallicola n. sp. 



Second joint of labial palpi white with three indistinct dark brown annu- 

 lations; brush dirty white with dusky tip; terminal joint white with two 

 clear cut black annulations. Antennae thick, ochreous with black annu- 

 lations. Face and head ochreous white, head sprinkled with fuscous. 

 Thorax whitish fuscous. Forewings light fuscous with three black costal 

 dashes, one near base, one on the middle and one at apical third; these 

 black costal spots are exteriorly edged by thin, ill-defined white lines, 

 which continue obliquely across the wing, the two outer ones meeting on 

 termen just below apex; two longitudinal black streaks on the middle of 

 the wing, one just before and one after the end of the cell; before and below 

 the first of these is a small group of slightly raised, rust-red scales on the 

 fold; cilia fuscous dusted with black. Hindwings light fuscous with 

 ochreous fuscous cilia; in the male with a large expansible, bright yellow 

 hair tuft at base. Legs ochreous white sharply barred with black; tarsi 

 with black annulations. Alar expanse: 13 mm.
