430 on the butterflies of japan and corea. [may 3, 



146. Hesperia ochracea. 



Pamphila ochracea, Brem. Lep. Ost-Sib. p. 33, t. i. fig. 11. 

 This seems to be rather a rare species ; I took it at Gensan in 

 June, and Nagahama, on Laive Biwa, in July. 



147. Hesperia rikuchina. 



Pamphila rikuchina, Butl. Cist. Eut. ii. p. 285 (1878). 



This species is very distinct from the last. I took a long series 

 of it at Nagahama and Tsiiruga in July, and none of the specimens 

 have one-third as much yellow as ochracea ; there is scarcely any on 

 the hind wings and none on the costal and inner margins of the fore 

 wings. 



This species occurs also at Nikko {Pryer). 



148. Hesperia flava. 



Pamphila flava, Murray, Ent. Mon. Mag. xii. p. 4 (1875). 

 Common all over Japan ; I also took it at Fusan, Corea, in June ; 

 there appear to be several broods. 



142. Cyclopides morphexjs. 



Papilio morpheas, Pall. Reise, i. p. 471 (1771). 



Common at Gensan in June. 



150. Cyclopides ornatus. 



C. ornatus, Brem. Lep. Ost-Sib. p. 33, t. ii. fig. 5. 

 This species occurs in Central Japan and Yesso. 



151. Pyrgus inachus. 



P. inachus, Men. Schrenk's Reise, p. 46, t. iv. fig. 2. 

 Occurs in several localities in Central Japan, but is far from 

 common. 



152. NiSONIADES MONTANUS. 



Pyrgus rnontanus, Brem. Lep. OstSib. p. 31, t. xi. fig. 4. 



Nisoniades rusticanus, Butl. Journ. Linn. Soc, Zool. ix. p. 58 

 (1866). 



Common all over Japan in spring. I have specimens from Ningpo, 

 Japan, and Amurlaud ; they all show a tendency to variation, but 

 nothing of any specific importance. . 



153. Syricthus maculatus. 



Syricthus maculatus, Brem. & Grey, Schmett. nordl. China's, 

 p. 11. 



Pyrgus maculatus, Men. Cat. Mus. Petr. i. t. v. fig. 5. 



P. sinicus, Butl. Ann. & Mag. Nat. Hist. ser. 4, vol. xix. p. 96. 



Common in Japan and Corea. 



Sinicus differs from maculatus in its smaller spots, and in the 

 absence of a second (siibmarginal) white band on the underside of
