0. Papilio codriis toealensis subsp. nov. 



S. Uppersifle : darker green thiui in rodrux codrux Cram, and coilrus medon 

 Feld.; the median maenlar band consists of nine spots, wliich are of the same pale 

 green colonr as in codrns codrus ; the last spot is rounded posteriorly, and measures 

 at the submediau vein ."),f mm. in length; the length of tlie preceding spot is (i mm. 

 at snbmedian vein and 5 mm. at lower median branch ; the two next spots are equal 

 in length (5 mm.). The hindwing is more prolonged than in medon, the first 

 median vein (traversing tail) having a length of 34 mm.; the grey scaling of the 

 basal half of the wing does not extend on the disc beyond the end of the cell, and 

 the tip of the tail is whitish grey for 1^ mm. 



Underside : darker brown than in medon ; the median band broader than above, 

 the last fom- spots touching each other and having somewhat increased in length. 

 Hindwing with a white mark behind the costal vein, situate 16 mm. from the base 

 and 11 mm. from tlie end of the costal nervure ; the mark is rounded (diameter 

 2^ mm.), and behind it there are some grey scales ; between veins 2 and 4 there are, 

 near the outer margin of the wing, two small patches of grey scales. 



?. Agrees with the malf, but the deep green gloss is absent from the upi)er- 

 side ; the tip of the tail is whitish grey to a greater extent (3 mm.), and tliere is a 

 huffish white, minute, marginal spot at the end of the second median branch of the 

 hindwing below. 



The variation is very slight. Tlie grey submarginal patches of scattered scales 

 on the underside of the hindwing between veins 2 and 4 are sometimes absent ; in 

 one of the/emales the dimensions of the costal mark of the left hindwing below are 

 only 1 and H mm., while those of the right hindwing are 2 and 2i mm. 



I/ri/j. Kei Toeal (Little Kei Island), collected by Capt. H. Cayley Webster, 

 January to March ISrn;. 



Is easily distinguished frnni /'. rodr/i.s codrKu Cram, by the presence of a large 

 pale green mark behind the submedian vein on the forewing; from codrus gilolensis 

 AVall. by the deeper green colour of tlie upperside (in S), the longer hindwings, 

 the larger and less rounded spots of the median band, and the costal mark on the 

 underside of the hindwing standing nearer the end of the costal nervure; from 

 codrus medon Feld. by the narrower median band, tlie less extended grey scaling 

 on tlie upperside of tlie hindwing, and the very much smaller costal mark. 



T. Papilio eurypylus melampus sulisp. nov. 



J. Forewing longer and Uiirniwcr than in tiie other Papuan races oi eurypylus, 

 vein 5 having a length of lo mm., vvliile the total lengtli of the wing is 44 mm. 



Upperside : median Ijand nearly as in /'. etaypylus euryjiyl/ts L., the last four sjiots 

 measuring in length 5, 7|, >*, and S mm. respectively; the last three not separateil 

 from one another; the preceding one is separated by the black vein ; cell with four
