408 MR. J. H. LEECH ON THE BUTTERFLIES [May 3, 



18. PlERIS DAPLIDICE, L. 



Var. bellidice, O. 



Anthucharis belemida, var. orientalis, Brem. Lep. Ost-Sib. p. 8. 



This species occurs at Gensaii in June, flying over corn-fields in 

 the neighbourhood of the Japanese settlement ; it does not differ from 

 European specimens. 



19. Anthocharis scolymus. 



A. scolywus, Bntl. Journ. Linn. Soc, Zool. ix. p. 52 (1866). 



A. thunbtryii, de I'Orza, Lep. Jap. p. 14 (1849). 



Common all over Japan in early spring ; it is very variable in size. 



20. Leucophasia sinapis, Linn. 



Var. amurevsis, Me'n. Schrenk's Raise, p. 1,5, t. i. figs. 4, 5. 



L. sinensis, But!. Cist. Ent. i. p. 173(1877). 



L. vibilia, Jans. Cist. Ent. ii. p. 272 (1878). 



L. morsei, Fenton, P. Z. S. 1881, p. 8.5.5. 



Common all over Japan and at Gensau. All the intermediate forms 

 between amwensis and sinapis exist, and forms without any black 

 apex to the fore wing corresponding to var. diniensis are not unusual. 



21. Rhodocera rhamni, Linn. 



B. 7iipalensis, Doubl. Gen. Diurn. Lep. p. 71 (1847) ; Gray, Lep. 

 Nep. t. V. fig. I (1831). 



R. maxima, Butl. Trans. Ent. Soc. 1885, p. 407. 



R. aspasiu, Me'n. Schrenk's Reise, p. 17, t. i. fig. 8. 



R. acuminata, Feld. Wien. ent. Mon.vi. p. 23 (1862). 



Occurs all over Japan and Corea. The rhamni (maxima) form 

 occurs at low elevations in Central Japan. I only took " acuminata " 

 in the mountains ; from Gensan I have a specimen of true rhamni, 

 and I have just received from Ningpo two specimens which resemble 

 acuminata in the shape of the wing, and rhamni var. farinosa ' in 

 colour. There can be little doubt that these refer to one species, but 

 I can form no opinion with any certainty until I receive larger series. 



22. Colias PALiENO, Liuu. 



Occurs in Yesso and mountain-districts of Central Japan. 



23. CoLiAS hyale, Linn. 



C. poliographus, Motsch. Et. Ent. ix. p. 29 (1860). 

 C. simoda, de I'Orza, Lep. Jap. p. 16 (18G9). 



C. neriene, Fisch., Motsch. Et. Ent. ix. p. 29. 

 C. erate, Esp., Murray, Ent. Mon. Mag. xiii. p. 34 (1876). 

 C. erate ah helictha, Led., Biem. Lep. Ost-Sib. p. 93. 

 C. siihaurata, Butl. Ann. & Mag. Nat. Hist. ser. 5, vii. p. 138. 

 C.elwesii, Butl. Ann. & Mag. Nat. Hist. ser. 5, vii. p. 135. 

 C. pallensi, Butl. Journ. Linn. Soc, Zool. ix. p. 50. 

 Common all over Japan and Corea. The spring form is rather 

 smaller than the summer brood. 



1 B. farinosa, Zell. Isis, 1837, p. 5 ; Mann, Wien. eut. Mon. v. p. 157, t. ii. f. 6.
