6 Notes on the Lepidoptera of America. 
Exxpanse, 4,1.75 inch. Length of body, 0.85 inch. 
Habitat.—Canada West (Saunders). 
We have as yet but a single male specimen before us, which 
came originally from Mr. Bowles’ Collection. We have con- 
jectured (L c¢.) that Sesia ruficaudis, Walker (non Kirby), was 
based upon the present species. From a comparison between 
Kirby’s description and that given in the British Museum 
Lists, it is evident that these refer to distinct species, and the 
descriptions have been properly kept apart by Dr. Clemens. 
From the brevity of Mr. Walker’s description, it cannot be 
properly ascertained what species is referred to, and the few 
points of resemblance between the description of S. ruficaudis, 
Walker, and H. gracilis, nob., may be accidental, a view which 
derives some support by the circumstance that Mr. Walker 
adds to his deseription the remark ; ‘This is probably a mere 
variety of S. thysbe”—a phrase that could not properly be 
applied to the very distinct H. gracilis. We have already 
(1. c.) given Kirby’s deseription of S. ruficandis, a description 
which will not apply to any species known to us, but probably 
to one which yet remains to be rediscovered.
