We have as jet but a single male specimen before us, which 

 came originally from Mr. Bowles' Collection: We have con- 

 jectured (1. 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 description the remark : " This is probably a mere 

 variety of S. thysbe " — a phrase that could not properly be 

 applied to the very distinct II. gracilis. We have already 

 (1. c.) given Kirby's description of S. ruficaudis, a description 

 which, will not apply to any species known to us, but probably 

 to one which yet remains to be rediscovered.
