20. Hemaris BUPFALOENSIS. 



Hamorrhagia buffaloensis, Grote & Robinson, Ann. Lye. Nat. Hist. New York, vol. viii. p. 437 

 pi. 16. figs. 18, 19 (1867). 



Buffalo. 



Very closely allied to, if not identical with H. ruficaudis of Walker (1 Kirby) ; the 



body, however, seems greener in colouring, and the cell of primaries less open. 



21. Hemaris gracilis. 



Ilamorrhagia gracilis, Grote & Robinson, Proc. Ent. Soc. Phil. vol. v. p. 174, pi. 3. figs. 1, 2 (1865). 



Trenton Falls, New York (E. Boubleday). B.M. 



This may at once be distinguished from even the most similar examples of //. ruficaudis 

 (Kirby 1) 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 Chamcesesia (Bull. Buff. Soc. 

 Nat. Sci. i. p. 8, 1873). 



22. Hemaris floridensis. 



Htemorrhagia floridensis, Grote & Robinson, Ann. Lye. Nat. Hist. New York, vol. viii. p 439 

 pi. 16. fig. 20 (1867). 



Florida. 



Allied to II. fuscicaudis, but with the external margin narrower and not dentated ; 



in H. fuscicaudis it is much more strongly dentated than in //. thysbe. 



23. Hemaris fuscicaudis. 



Sesia fuscicaudis, Walker, Lep. Het. viii. p. 83. no. 6 (1856). 



Hcemorrhagia fuscicaudis, Grote & Robinson, Proc. Ent. Soc. Phil. vol. v. p. 174 (1865). 



Georgia (Abbot). Type, B.M. 



Unquestionably the finest species in the genus. 



Section Cepiionodes, Hubner. 

 (Potidcea, Wallengren.)
