dorsum; ocellus consisting of two vertical bars of leaden scales in- 

 closing three or four short black streaks or dots; from outer third 

 of costa a narrow oblique band of lead colored scales extending to 

 and joining the inner bar of the ocellus ; a few faint whitish strigulae 

 on outer third of costa ; at apex a small round black dot ; cilia fuscous 

 brown with a darker basal line. Hind wing smoky fuscous; cilia 

 concolorous with a very fine whitish basal line. 



Male genitalia of type figured. 



Alar expanse. — 12 mm.

Described from male type from Aweme, Manitoba ("Criddle.

This is the species that has figured in our lists and been deter- 

 mined in our collections as the European incarnana Haworth. It 

 differs in genitalia (compare figs, 66, 67) as well as in pattern. The 

 true incarnana has a distinct black spot on the disk and considerable 

 whitish scaling on outer fourth of fore wing both of which are lack- 

 ing in substitutionis. Moreover the latter has a black dot at apex 

 which is entirely absent in the European species. The true incarnana 

 probably does not occur in this country and should be dropped from 

 our lists.

The genitalia of Clemens two species are alike in all details. 

 There is some slight color differences, but they grade into each other 

 through several specimens, and both have the same larval habit 

 and food plants, being inquilin feeders in galls on Salix. They have 

 also been reared, according to Kearfott,^'^ from larvae crumpling the 

 young leaves. I have compared our specimens carefully with the 

 types and have no hesitation in making the synonymy.
