MR. A. G. BUTLER ON THE BUTTERFLIES OF MALACCA. 
Genus Terinos, Boisduval. 
1. Terinos teuthras, Hewitson, P. Z. S. p. 89 (1862). ? , Malacca. 
2. Terinos robertsia, Butler, Ann. & Mag. Nat. Hist. ser. iii. yol. xx. p. 400, pi. 8. 
figs. 2-4 (1867). <5 ?, Malacca. This species appears to be tolerably common. Mr. 
Distant took both the above butterflies at Province Wellesley. 
Genus Messaras, Doubleday. 
1. Messaras erymanthis, (Papilio erymanthis) Drury, 111. Ex. Ent. i. pi. 15. figs. 3, 4 
(1773). c? ? , Malacca ; Penang. 
Genus Atella, Doubleday. 
1. Atella phalanta, {Papilio plmlanta) Drury, 111. Ex. Ent. i. pi. 21. figs. 1, 2 (1773). 
d ? , Malacca ; Penang. 
2. Atella siniia, ( Terinos sinha) Kollar, Hugel’s Kaschm. iv. 2, p. 438 (1848). 
S , Malacca. 
Genus Cynthia, Eabricius. 
1. Cynthia erotella, n. sp. Allied to C. erota , but much smaller, brighter in colour; 
the primaries generally comparatively shorter, the costal margin more arched, the ocelli 
smaller in the male, and the discal lunulated line much less strongly defined ; secon- 
daries of the female with four ocelli, with broad bright orange irides. Wings below 
slightly more reddish in colouring, with scarcely a trace of pearly grey clouding on the 
external area. Expanse of wings, <$ 3 inches 2-8 lines, ? 3 inches 7 lines. c? $ , Ma- 
lacca. 
I have examined a good series of examples, and am therefore confident of the dis- 
tinctness of this species. In general size and the indistinctness of the lunulated discal 
line it agrees with C. deione ; but it is altogether brighter in colour, with longer tails 
to secondaries, and a different arrangement of the lines on the under surface of the 
wings. Mr. Distant took it at Province Wellesley. 
Genus Parthenos, Hiibner. 
Parthenos lilacinus, n. sp. (Minetra gcimbrisius , Hewitson, Gen. Diurn. Lcp. pi. li. 
fig. 2). Differs from P. gambrisius in the lilac internal area of primaries and basal area 
of secondaries above ; in the blue-green basal areas of secondaries below, and the much 
better defined series of black liturae beyond the hyaline band of primaries. Expanse of 
wings 4 inches 2 lines. S ? , Malacca ; Penang. 
I have seen long series of both the Indian and Malayan forms, and am therefore 
satisfied that the differences are constant. The Eabrician type agrees with our examples 
from Silhet. 
Genus Cyrestis, Boisduval. 
1. Cyrestis rahria, Moore, Cat. Lep. E.I. C. i. pi. 3 a. fig. 2 (1857). S ?, Malacca; 
? , Penang.
