Beneath : Primaries almost tmiformly blackish fuscous, the veins slightly 

 darker, some scattered pale scaling along costal region; secondaries somewhat 

 paler than above but heavily suffused with scattered blackish scales. A dark 

 discoidal spot prominent. At least a trace of a common line crosses both pair 

 of wings. 



Expanse: 31-37 mm. 



The present species belongs to the perplexa group of Lasionycta 

 with which it is almost identical in superficial appearance, but it is 

 easily separated from the other species of the group by the more 

 heavily serrate male antennae. Attention is called to the transfer of 

 perplexa to Lasionycta by Barnes and Lindsey, 1921, Psyche, XXVIII, 

 157. 



In addition to the types, the Barnes Collection possesses four speci- 

 mens from Laggan, Alta. which probably belong to this species.

CUCULLIINAE 



?C0P1CUCULLTA CUCULLIOIDES sp. nOV. 



Head and thorax mixed black and white scales. Tegulae crossed by a dis- 

 tinct black line. Primaries: ground color whitish, heavily powdered with black 

 scales and appearing gray. Lines and ordinary spots obsolescent except a black 

 terminal line. T. a. line, when traceable, produced to points in the cell and 

 the submedian fold. A thin, short, black, basal dash present below cell. A 

 distinct black dash in submedian fold from near the apex of the submedian point 

 of the t. a. line to the outer margin. A gray apical shade present. Some black 

 shading along inner margin. Fringe gray. Secondaries : white, suffused with 

 fuscous along outer margin and on the veins. Fringe white. Beneath : white, 

 more or less heavily powdered with gray. 



Expanse: 28-31 mm. 



Obviously belongs to the eulepis series of Copicucullia, both the 

 habitus and genitalia affirming this relationship, but the claws on the 

 fore tibiae are poorly developed; being mere outgrowths of chiten, and 

 covered with scales, so that the insect might easily be placed in 

 Cucullia.
