ON CERTAIN BRITISH LEPIDOPTERA IN EASTERN ASIA. 83 



black, being by far the most pronounced var, Idppocrates I have 

 yet seen. Every specimen was much larger than the parent." 

 An almost tail-less form occurs in Kashmir. 



PiERis BRASsic^, Linn. — So far this species does not seem to 

 have been received from either China or Japan. The Indian 

 examples do not differ materially from European specimens, 

 except that those taken at high elevations (11,000 — 17,000 ft.) 

 are smaller. 



PiERis RAP^, Linn. —Common in Japan, Corea, and N. China, 

 where it is often abundant in market gardens and on other 

 cultivated ground, as in England. A local form of this species, 

 known as criicivora, has the fore wings of the female thickly 

 sprinkled with grey-brown scales, especially at the base ; in the 

 male the second spot of the under side of the fore wing is repro- 

 duced more or less distinctly on the upper surface. This form 

 has been considered as a local race of P. brassicce, but Mr. Leech 

 has shown that it is connected by intermediate forms with 

 typical P. rapcB, which also occur in the same localities ; and 

 he adds : — " Mr. H. Pryer informs me that the larvae, which 

 feed on the cultivated Cruciferse, do not differ from the typical 

 forms, nor does the pupa." 



PiERis NAPi, Linn. — Extremely variable: occurs all over 

 Japan and Corea, and has been received by Mr. Leech from 

 several localities in N.W. China. Although typical napi are by 

 no means uncommon, most of the specimens from East Asia 

 are of the form melete, Men. Mr. Leech says of it : — " In 

 Central and Northern Japan napi seems to be the spring form, 

 and there are specimens in Mr. Fenton's collection in no way 

 separable from British examples, and I have all the intermediate 

 forms between Qiajn and melete in my own collection. In 

 Southern Japan the larger and darker forms predominate, and 

 there is less difference between the broods." Besides other 

 named forms of this species occurring in East Asia is one 

 analogous to bryonies from Europe ; this has been named aglaope 

 by Motschler, who obtained specimens from Japan. 



Ehodocera rhamni. — Various forms (?) of this species are 

 found in East Asia, and these are referred to by Mr. Elwes as 

 follows : — " The European form li. rhamni was found in the 

 Burisja Mountains by Piadde, and, according to Bremer, at 

 Pekin. The form called Pi. aspasia occurs in various parts of 

 the Amur region, and is usually known by its rather smaller size 

 and paler colour, and, according to Menetries, may be certainly 

 distinguished by the shape and venation of the wings, though I 

 am unable to follow the distinctions he draws in the specimens 

 before me. The Japanese form is like the one described by
