904 MR. H. J. ELWES ON THE BUTTERFLIES [NoV. 15, 



and placed in a different genus by Moore in liis recent paper on the 

 genus. 



Yphthima baldus, Fab. Syst. Eut. p. 323 (1793). 



? Y. argns, Butl. Journ. Linn. See, Zool. ix. p. 5G (1866). 



I follow Dr. Staudinger in considering the common Amur species 

 as Y. baldus, Fab., though in such a genus it is difficult to be sure. 

 I think there is little doubt that the Japanese Y. argus is identical 

 with the Amur insect, though the underside, as a rule, is paler. 



It appears to be common in Japan. 



Y. motschulskyi, Brem. & Grey, Schmett. nordl. China, p. 8 

 (1853). 



Satyrus motsehulshji, Men. Cat. Mus. Petr. t. vi. fig. 5. 



Distinguished from the last by having one ocellus on the upper- 

 side of hind wing instead of two or three, and three on the under- 

 side, of which that at the anal angle is double. It is extremely near 

 to, if not identical with, Y. nareda, Moore, from the N.W. Himalaya. 

 Specimens referred to this latter species are in Dr. Staudinger's 

 collection from Japan ; and a Himalayan specimen referred to 

 Y. motschulshyi is in the British Museum. It occurs also at Pekin ; 

 and a very similar, though smaller form, is in Pryer's collection from 

 Shanghai. 



? Y. AMPHiTHEA, Men. Schrenk's Reise, p. 41, t. iii. fig, 10. 



Nothing is known of this species except Menetries's figure and 

 description, based on a single specimen from the Amur, I very 

 much doubt whether it can be recognized in life, 



Y, zoDiA, Butl. Trans, Ent. Soc, 18/1, p. 402, 



A small species with the underside of the hind wings very pale, 

 and the ocelli reduced to mere points. It comes very near Y. methora 

 from India, and is perhaps hardly separable. It is found in the 

 Snowy Valley, hills of Ningpo, whence I have three specimens col- 

 lected by Fryer. 



Y. evanescens, Butl. Ann, & Mag. Nat, Hist, ser, 5, vii. p. 134, from 

 Nikko, Central Jaj^an, seems to be a mere synonym of this — though, 

 as it is described from a single specimen, it is impossible to say with 

 certainty. It is described as resembling " Y. lisandra, Cr., above, 

 and Y. zoclia beneath ; the ocelli arranged as in Y. stellera." 



Y. MEGALOMMA, Butl. Cist. Eut. i, p. 236 (1874), 

 This reallj' does seem to be a good and distinct species, easily 

 known from any I have seen by its shape and large ocelli. 

 Discovered by Pryer on the Ningpo hills. 



Pal^eonympha opalina, Butl, Trans, Ent. Soc. 1871, p, 404 ; 

 Lep, Ex. p, 86, t. xxxiii. fig. 3. 



This genns appears to be j)eculiar to Central China. It was dis- 

 covered by Pryer at the same time and place as the last (see Ent. 

 Month. Mag. 1877, p. 53).
