556 MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 



Genus Plesioneura, Pelder. 



1. Plesioneura eolus, (Papilio folus) Cramer, Pap. Exot. i. pi. 74. fig. P (1779). 

 <? , Malacca ; Penang. 



2. Plesioneura alysos, Moore, P. Z. S. p. 789 (1865). 3 ? , Malacca. 



3. Plesioneura 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., S ? , Malacca (5 examples). 



4. Plesioneura dan, (Papilio dan) Pabricius, Mant. Ins. ii. p. 88. n. 798 (1787). 

 S , Malacca. 



5. Plesioneura Pinwilli, n. sp. (PL 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 ochreous ; neck 

 below white : antennae black above, testaceous below. Expanse of wings 2 inches 2 lines. 

 <S , Malacca. Most nearly allied to P. tabrica of Hewitson from Darjeeling. 



Genus Tagiades, Hiibner. 



1. Tagiades ravi, (Pterygospidea ravi) Moore, Proc. Zool. Soc. p. 779 (1865). 

 S % , 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, (JPterygospidea gana) Moore, P. Z. S. p. 780 (1865). 6 ? , Malacca. 

 Originally discovered at Bengal. 



3. Tagiades calligana, n. sp. (PI. LXIX. fig. 11.) Closely allied to T. atdcus, 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. J 1 ?, Malacca 

 (2 examples).
