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



18. PlERIS DAPLIDICE, L. 



Var. bellidice, O. 



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



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

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

 European specimens. 



19. Anthocharis scolymus. 



A. scolymus, Butl. Journ. Linn. Soc, Zool. ix. p. .52 (1866). 



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



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



20. Leucophasia sinapis, Linn. 



Var. aniurensis. Men. Schrenk's Reise, p. 15, t. i. figs. 4, 5. 



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



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



L. morsel, Fentou, P. Z. S. 1881, p. 8.5.5. 



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

 between amurensis and sinapis exist, and forms without any black 

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



21. Rhodocera rhamni, Linn. 



R. nipalensis, Doubl. Gen. Diurn. Lep. p. 71 (1847) ; Gray, Lep. 

 Nep, t. V. fig. 1 (1831). 



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



R. aspasia. Men. 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 liave 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 PAL.(ENO, Liun. 



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

 C. erate ab helictha. Led., Brem. Lep. Ost-Sib. p. 93. 

 C. suhaurata, Butl. Aim. & 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 R. farinosa, Zell. Isis, 1837, p. 5 ; Manu, Wien. eut. Mon. t. p. 157, t. ii. f. 6.
