Notes on Table IV. 

 The females of Euripus halitherses (D. & H.) are extremely 

 variable, in fact no two specimens of the fine series of this species 

 in the Sarawak Museum collection are exactly alike, and almost 

 every specimen deserves a varietal name of its own, as has been 

 done to a certain extent for the mimetic Fapilio paradoxus 

 telesicles (Feld.) by Rothschild &■ Jordan (Nov. Zool. vol. ii.). 



It is possible, however, to distinguish three main groups. One, 

 almost entirely dark blue, is a mimic of Trepsichrois nvulciber (Or.), 

 and approximates to^. cinnamomeus (Wood-Mason). Another is 

 dark brown with a blue gloss and an oblique discal white fascia 

 on the fore wings and some white streaks on the hind wings, and 

 is a close mimic of Danisepa lowei (Butl.) d ; this group is 

 nearest to U. pfeiferce (Feld.). The third group, near U. euploeoides 

 (Feld.), corresponds closely in coloration and markings with 

 Danisepa lowei $ . A considerable number of variations of this 

 highly variable species have been separated into distinct species, 

 but I prefer to regard these as merely varietal names. 



The females of Danisepa rhctdamanthus (Fab.) (the continental 

 form of Danisepa lowei) have much more white on the upper side 

 and are readily distinguishable from the Bornean representatives, 

 though the males are practically indistinguishable. In accordance 

 with this, the continental forms of Dttripits halitherses $ of the 

 eup)loioides type have larger white markings on the upper side 

 than the insular forms ; I have not seen continental forms of 

 Isharta rhadamanthus (Fab.) or of Papilio caunus (Westw.), 

 but I expect that a parallel variation will be found in these. It 

 is curious that the ahnost identical males of D. rhadamanthv s and 

 D. lowei are extremely common in their respective localities, whilst, 

 on the other hand, the female of D. loicei is very rare, and the 

 very different female of D. rhadamanthus is as common as its male. 



Hypolimnas anomala (Wall.) is very Euploeine in its flight as 

 well as in ajDpearance ; it is not an uncommon species and the 



'' [A closely similar example of Miillerian mimicry was sent for exhibition to the 

 Entomological Society in 1894 by Mr. G. A. J. Rotimey (see Proc. Ent. Soc. Lond. 

 1894, p. xv). The species Phauda fiammans (Walk.) and SerinetJia aiigur (Fab.) 

 were observed in abundance on roots and trunks of trees in Mysore in Nov. 1893 by 

 Mr. Rothney.— E. B. P.]
