]62 MESSES. H. J. ELWES AND JAMES EDWAKDS : 



! Hesperia bieti. 

 Syrichthus bieti, Oberthiir, Etud. d'Ent. xi. p. 26, pi. vi. fig. 50 (1886). 

 Hespci-ia bieti, Leech, Butt. China &c. p. 578 (1894.)- 



Hab. Western China (Jide Leech); N.E. Tibet {^de Al/pheralcy). 



Hesperia oberthuei. 



Syrichthus oberthiiri. Leech, Entomologist, sxiv. Suppl. p. 59 (June 1891). 

 Syrichthus delavayi, Oberthiir, Etud. d'Ent. xv. p. 20, pi. iii. fig. 31, (J (July 1891). 

 Hesperia oberthiiri, Leech, Butt. China &c. p. 579, pi. xli. fig. 5, c? • 



Hab. Western China {fide Leech) ; Yunnan {fide Oberthiir). 



We rely on Mr. Leech's identification of H. delavayi with H. oberthuri, not having 

 seen the former. 



! Hesperia zona. 



Scelothriw zona, Mabille, Ann. Soe. Ent. Pr. 1875, p. ccxiv. 



Scelothri'x [Pyrgus) alhistriga, Mabille, t. c. 1876, p. xxvii. 



Pyrgus sinictts, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xix. p. 96 (1877). 



Syrichthus sinicus, Pryer, Rhop. Nihon. p. 35, pi. x. fig. 22 (1889). 



Hesperia zona. Leech, Butt. China &c. p. 577, pi. xli. figs. 1, 3 (1893-4). 



Hab. Japan, Shanghai {Pryer) ; Central China {Pratt) ; Korea {Leech). 



We rely on Mr. Leech's identification of H. sinicus with H. zona., which is, we 

 believe, correct. We do not feel equal confidence in the constancy of the characters 

 by which he separates it from H. maculafus, especially as the difl'ereuces in their 

 genitalia are of degree only. 



! Hesperia maculatus. 

 Syrichthus maculatus, Bremer & Grey, Schmett. N. China's, p. 11, pi. iii. fig. 6 (1853) ; Pryer, 



Rhop. Nihon. p. 35, pi. x. fig. 31 (1889). 

 Pyrgus maculatus, "Menetries, Cat. Mus. Petr. pi. v. fig. 5 (1855). 

 Hesperia maculata, Leech, Butt. China, &c. p. 576, pi. xli. fig. 2, (J (1893-4).

! Hesperia thibetanus. 

 Syrichthus maculatus, var. thiheta7ius, Oberthiir, fitud. d'Ent. xv. p. 20, pi. iii. fig. 27 (1891). 

 Hesperia thibetana, Leech, Butt. China &c. p. 578 (1894). 



Hab. Western China {fide Leech). 



We follow Mr. Leech in treating this as a distinct species, as our material is insufllicient 

 to decide the question ; the differences noted are not, however, very striking. 



! Hesperia sid^.

 (1798-1803).
