20. Hemaris buffaloensis. 



Hcemorrhagia 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 (? Kirby) ; the 

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



$ ( 21. Hemaris gracilis. 



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



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



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

 (Kirby V) 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). 



* f 22. Hemaris floridensis. 



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

 pi. 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. 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).

Unquestionably the finest species in the genus.
