inner fourth of dorsum. Cilia very pale fuscous-brown, heavily dotted

 white. 



Expanse, 24-28 mm. 



Five specimens, all Denver, Colo., four from Dr. Barnes's collection,

Eucosma tomoniifia, sp. nov. 



Head, palpi, antenna and thorax hoary-gray; abdomen and legs light 

 cinereous-gray, latter dusted with coppery-brown. 



Fore wing hoary-gray, with two blackish-brown dorsal spots. Even 

 under a lens the ground colour is almost uniform, with but very faint 

 strigulations. The costa is streaked with long lines of grayish-brown; one 

 from just beyond middle goes to anal angle, beyond this is a short dash, 

 then a longer line that curves outwardly and ends in middle of termen, 

 enclosing the rounded ocellic area ; between the latter line and apex are 

 two shorter lines that join beneath costa, and continue as a single line to 

 termen beneath apex. The gray ground separating these faint brown lines 

 is slightly shining, and on the costa, in each of the gray interspaces, is a 

 narrow darker dash. Below the middle the ocellic area is shining gray, in 

 which are a few horizontal black dashes. The dorsal spots are very con- 

 spicuous on the light ground colour; the inner is a flattened triangle with 

 narrow base, on inner third of dorsum ; it curves obliquely outward, the 

 upper end, as a fine line, reaching middle of wing ; the outer spot is 

 ovate, with its broadest and flat side between outer third of dorsum and 

 anal angle ; it does not extend beyond lower fourth. Cilia speckled gray_ 



Hind wing light smoky-gray, paler beneath costa, cilia whitish-gray ; 

 under side the same, faintly reticulated at outer end. Under side fore wing 

 smoky-fuscous, whitish beneath fold. 



Expanse, 12-15 mm.
