tlie Corea. It also occurs iu Central China at Cliang-yang and Kiukiaiiji-, 
and in Western China at Chia-ting-fu. 
I have beautifully executed drawings of the types of zona and albistriqa, 
Mabille, and consider that both, together with siniciis, Butler, are referable 
to one species. Zo)ia^sinicus is the usual form met with, and has the dark 
submarginal band on under surface of secondaries well developed ; var. al/j/- 
■sfn'ga is a slightly smaller form, in which the ground-colour of under surface 
is more uniform in tint and the black submarginal band does not extend far 
beyond the anal angle. In some specimens the dark central band on under 
surface of secondaries is entirely obliterated as in fig. 3. 
Hesperia thibetana. 
Si/ric/it/iiis maculatiis, var. thlbetatnis, Obertliiir, Etiul. d'Eatom. xv. p. 20, pi. iii. fig. 27 
(1891). 
Yc-iy similar to H. maculata on the upper surface, but the white spots are generally rather 
smaller and the outer band of spots on secondaries is not elbowed. Oq the under surface the 
apex of primaries is white enclosing a dash of olivaceous brown, instead of being entirel_v 
brown ; the pattern on secondaries is similar to that of maculata, but the colour of ground 
and markings is the same as in //. hieti. 
Expanse 32-36 millim. 
Of this species, Avhich M. Oberthiir has considered to be a form of 
II. maculata, I have examples from Ta-chien-lu and AVa-ssu-kow in Western 
China, Avhere they were taken in May and June. 
Hesperia bieti. 
Sijrkhthus bieti, Oberthiir, Etud. d'Eiitom. xi. p. 20, pi. vi. fig. 50 (188G). 
" Voisin de macidatus dont il diffcre peu en dessus, mais tres distinct en dessous par les dessins 
gris jaunatre de ses ailes inferieures. 
" Le dessous de I'abdomen est blanchatre." {Oberthiir, 1. c.) 
This species is fiiirly plentiful at Ta-chieu-lu and Wa-ssu-kow, Western 
China, in May and June. 
Alpheraky * records ^S*. bifti from Tangout, plateau of xlmdo. AI. Grum- 
Grshimailo sent me a specimen as this species from the Nian-shan mountains, 
Thibet ; but it is quite diiferent to any Hesj^eria with which I am acquainted, 
and will probably prove to be ncAv.
