Notes on TABLE IV. 
The females of Huripus 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 Papilio paradoxus 
telesicles (Feld.) by Rothschild & Jordan (Novy. Zool. vol. i1.). 
It is possible, however, to distinguish three main groups. One, 
almost entirely dark blue, isa mimic of 7'repsichrois mulciber (Cr.), 
and approximates to 4. cimamomeus (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.) ¢ ; this group is 
nearest to H. pfeiffere (Feld.). The third group, near #. eupleoides 
(Feld.), corresponds closely in coloration and markings with 
Danisepa lowei 2. 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 rhadamanthus (Fab.) (the continental 
form of Danisepa lowe?) 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 Huripus halitherses 2 of the 
eupleoides type have larger white markings on the upper side 
than the insular forms; I have not seen continental forms of 
Isbarta rhadamanthus (Fab.) or of Papilio caunus (Westw.), 
but I expect that a parallel variation will be found in these. It 
is curious that the almost identical males of D. rhadamanthus and 
D. lowei are extremely common in their respective localities, whilst, 
on the other hand, the female of D. lowei is very rare, and the 
very different female of D. rhadamanthus 1s as common as its male. 
Hypolimnas anomala (Wall.) is very Eupleeine in its flight as 
well as in appearance; it is not an uncommon species and the 
1 [A closely similar example of Miillerian mimicry was sent for exhibition to the 
Entomological Society in 1894 by Mr. G. A. J. Rothney (see Proc. Ent. Soc. Lond. 
1894, p. xv). The species Phauda flammans (Walk.) and Serinetha augur (Fab.) 
were observed in abundance on roots and trunks of trees in Mysore in Noy. 1893 by 
Mr. Rothney.—H. B. P.|
