Hemorrhagia buffaloénsis, Grote & Robinson, Ann. Lye. Nat. Hist. New York, vol. viii. p. 437, 
pl. 16. figs. 18, 19 (1867). 
Buffalo. 
Very closely allied to, if not identical with H. ruficaudis of Walker (? Kirby); the 
body, however, seems greener in colouring, and the cell of primaries less open. 
21. HEMARIS GRACILIS. 
Hemorrhagia gracilis, Grote & Robinson, Proc. Ent. Soc. Phil. vol. v. p. 174, pl. 3. figs. 1, 2 (1865). 
Trenton Falls, New York (EL. Doubleday). B.M. 
This may at once be distinguished from even the most similar examples of H. ruficaudis 
(Kirby ?) Walker, by the straight inner edge of the external brown border of primaries, 
the more heavily scaled discocellulars, and the smaller hyaline patch on secondaries. 
Grote separates it as a distinct group under the name of Chamesesia (Bull. Buff. Soc. 
Nat. Sci. i. p. 8, 1873). 
22, HEMARIS FLORIDENSIS. 
Hemorrhagia floridensis, Grote & Robinson, Ann, Lyc. Nat. Hist. New York, vol. viii. p. 439, 
pl. 16. fig. 20 (1867). 
Florida. 
Allied to H. fuscicaudis, but with the external margin narrower and not dentated; 
in H. fuscicaudis it is much more strongly dentated than in H. thysbe. 
23. HMARIS FUSCICAUDIS. 
Sesia fuscicaudis, Walker, Lep. Het. viii. p. 83. no. 6 (1856). 
Hemorrhagia fuscicaudis, Grote & Robinson, Proc. Ent. Soc. Phil. vol. v. p. 174 (1865). 
Georgia (Abbot). Type, B.M. 
Unquestionably the finest species in the genus.
