By the HON, WALTER KOTHSCHILD, Pii.I), 



PAPILIONIDAE. 



1. Troides aeacus formosanus subsp. uov. 



i. Differs from the ludian form of aeacus in the white spots of the fringe 

 of the forewing being much smaller, iu the wedge-shaped interuervular portions 

 of the black marginal baud of the hindwing being longer, in the abdomen being 

 clothed with red hairs beneath at the base and bearing (like aeacus from Central 

 and West China) two rows of black ^Mis ou each side ventrally. 



Hab. South Cape, Formosa (received from Monsieur de la Touche), ii i 6 . 



2. Papilio nubilus musianus subsp. nov. 



S. Differs from the Boruean form of nubilus, Iris VII. p. 314 (1894) (Brunei), 

 in the following points : Forewing above with three postdiscal white patches, the 

 uppermost between SC^ and SO"", the following two longer, between SC'' and R-, 

 all three sinuate externally, an indication of a fourth patch between R- and R^ 

 7 mm. from edge of wing ; marginal spots nine in number, ujipermost between 

 SC^ and SC^, spot between SC* and SC* extremely small, visible only with a lens. 

 Hindwing above as in nubilus nubilus, no submarginal spots. 



Underside. Forewing with four postdiscal patches from SC^ to R'*, upper three 



just beyond apex of cell, fourth smaller, a little closer to cell than to outer margin ; 



in inner angle, between M- and SM-, a small patch with a small spot in front. 



Hindwing : submarginal lunules R^ — M- very faintly marked ; third discal patch 

 measuring 10 mm. in length, externally obliquely cut off', slightly concave, the 

 fourth more regular, '.i|l mm. long. 



Hab. Upper Palembang district, o' s. lat., !l03' long. ; \ S, received from 

 J\Ir. J. Volcker. 



NYMPHALIDAE. 

 3. Cynthia obiensis sp. nov. 



(?. Wings above deeper iu tint than in arsinoc h-ova Amboina — • — Forewing : 

 median series of bars heavy, very oblique, upper one close to upper angle of cell, 

 bar M- — SM- 6 to 7 mm. from tip of SM- ; admarginal line of lunules as in 



arsinoc, submarginal lunules very faint, except the last. Hindwing : median 



series of bars very heavy, the line broken at veins, upper bar curved like letter 

 S, bar R'* — M' more or less longitudinal, being mostly j)laced along D', bar 

 M- — (SM') also marked. 



IJndei'side from base to median lines of bars rufous red, especially ou 



hindwing. Forewing : median bars not so heavy as above, but also placed in a 



very oblique row ; apical white spots larger than in arsinoc, brown spot in inner 



angle small. Hindwing : outer half rather heavily shaded with rnibus red : 



median line of bars somewhat concave.
