residing in Japan, has by careful breeding proved that 7'. h reals and 7\ maiutarimi are one 

 species, or rather what Mr. Pryer calls "temperature forms" of one species, and he accounts 

 for the fact of breeding so many intermediate forms from one hatch of eggs by the qualifying 

 conditions of " having reared these specimens in a cold room, without much direct sunlight.*' * 

 Neotropical species afford the same difficulty, and that excellent naturalist, Mr, Bates, has 

 supplemented his account of those of the Amazon Valley by a '* note" stating that "the species 

 of Twins are a most difficult study, and it is with some hesitation that I have described several 

 as new," He further remarks: — 1( Their specific characters are not at all trench aut ; the 

 peculiar markings which may serve to distinguish well-characterised examples of a species are 

 subject to become obsolete in other examples ; the species, again, present many local varieties 

 in different parts of their area of distribution/' f I fully entertain this view with regard to the 

 species or varieties found in the Malay ^Peninsula, and where I have been unable to find a 

 published name for any species have refrained from giving it a new one, prefering to have 

 that done by some local lepidopterist who could give certitude to his work by breeding the 

 different forms* 



The llev. L. 0. Biggs writes: — " These butterflies are often seen by dozens together in 

 moist places on the road, or singly near the Malay villages, under the shade of cocoa-nut 

 trees, or crowding round the inky pools too often found in closest proximity to the Malays' 

 dwellings. They, with the smallest Lyaxmdat, and the Skippers, are among the first to venture 

 out in the morning after heavy dew, or at any time after a storm." J

Male. Wings above bright sulphureous; anterior wings with the costal margin narrowly, the- apex 

 and outer margin broadly, and Hu- inner margin also broftily, black (the apical and outer marginal black 

 area is inwardly oblique and dentately sinuate* occupying about half the distance between end of cell and 

 apes of wing, and terminating somewhat narrowly at the outer angle). Posterior wings with the outer margin 

 somewhat broadly black and inwardly obscurely sinuate. Wings beneath less brilliant sulphureous than 

 above ; anterior wings with a tsurvud Mack line near base of cell, two connected disco-cellular black lines at 

 end of coll, and a fainter curved narrow blackish fascia near apex ; posterior wings with one or two small 

 blackish spots near base, two connected disco-cellular blackish lines at end of ceil, a submarginal series of 

 small blackish spots, preceded on the costa by a larger and darker one, and a series of small but dark 

 marginal spots placed between the nervules. Body above black, beneath with legs sulphureous, tarsi 

 in fu seated.

I have not received the female of this species, which is probably paler in hue than the 

 male, and with the blackish margins broader,
