MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 
Genus Plesionetjra, Eelder. 
1. Plesionetjra folus, ( Pajpilio folus) Cramer, Pap. Exot. i. pi. 74. fig. E (1779). 
3 , Malacca ; Penang. 
2. Plesionetjra alysos, Moore, P. Z. S. p. 789 (1865). 3 ? , Malacca. 
3. Plesionetjra Asmara (Moore in litt.). Similar to P. dan , but not tawny-tinted, 
the three spots in the centre of primaries united, and hyaline white : expanse of wings 
1 inch 8 lines, 3 $ , Malacca (5 examples). 
4. Plesionetjra dan, ( Papilio dan) Eabricius, Mant. Ins. ii. p. 88. n. 798 (1787). 
3, Malacca. 
5. Plesionetjra Pinwilli, n. sp. (PI. LXVIII. fig. 4.) Primaries black with a 
bluish shot; a broad oblique shining pale-yellow subhyaline patch, separated by the median 
nervure and its second and third branches into three spots ; two small spots of the same 
colour, placed obliquely below it, on the interno-median interspace : secondaries bright 
orange, the base and the apical portion of external border chocolate-brown ; remainder 
of outer border, a rounded spot at end of cell, a second near anal angle, and five, sub- 
marginal, touching the outer border, black : head and thorax greenish grey, vertex of 
head edged with sordid white ; abdomen orange banded with black. Primaries below as 
above, excepting that there is a bifid whitish spot above the end of the cell, a whitish 
spot at base of interno-median area, and that the inner margin is brown : secondaries 
bright orange ; the costal and outer borders irregularly purplish black ; fringe brown- 
ish ; a subcostal dash, a rounded spot at the end of the cell, and a reniform spot near 
the anal angle black : body below and legs bright ochreous, palpi pale oclireous ; neck 
below white : antennae black above, testaceous below. Expanse of wings 2 inches 2 lines. 
3 , Malacca. Most nearly allied to P. tabrica of Hewitson from Darjeeling. 
Genus Tagiades, Hubner. 
1. Tagiades rayi, ( Pterygospidea ravi) Moore, Proc. Zool. Soc. p. 779 (1865). 
3 ? , Malacca. I have compared this with the type, with which it entirely agrees. 
I have seen specimens of what is evidently a nearly allied species labelled as T. ravi ; they 
differ in having the hind borders of the secondaries above, and the abdominal half below, 
white. 
2. Tagiades gana, ( Pterygospidea gana) Moore, P. Z. S. p. 780 (1865). 3 ? , Malacca. 
Originally discovered at Bengal. 
3. Tagiades calligana, n. sp. (PL LXIX. fig. 11.) Closely allied to T. atbicus , but 
the secondaries much narrower, and the two black spots towards anal angle wanting, 
leaving only two submarginal black spots ; submarginal spots below contiguous, 
almost forming a border. Expanse of wings 1 inch 8 lines. 3 ?, Malacca 
(2 examples).
