patch ends posteriorly on the first median nervule, sometimes it reaches 

 the submedian nervure ; on the underside of the forewing the snbapical 

 band is sometimes present, usually absent ; on the liindwing there is 

 sometimes a discal series of large irrorated white spots from the costa 

 to the first median nervule, usually entirely absent; the blue and 

 orange submarginal markings are also more or less developed, some- 

 times both series are absent. It is very common on both Little and 

 Great Ke Isles. The larva is as variable as the butterfly, and feeds on 

 various trees, especially those of the Natural Order Aurantiacese. The 

 larva when young resembles a bird's dropping. When full-grown it is 

 smooth with no processes ; the head is pale green, the body is dark 

 green, becoming yellowish-green laterally, the second, third and fourth 

 segments beneath and the legs are brown, the fifth to thirteenth segments 

 beneath and the prolegs milky- white ; the fifth segment bears pos- 

 teriorly a broad transverse black band, and the eighth segment bears 

 an oblique short black band on each side just above the spiracles ; on 

 the fourth segment are two subdorsal milky-blue points on each side 

 one above the other, with a black spot just anterior to the spiracle ; on 

 the ninth segment are two subdorsal obliquely-placed milky-blue points 

 on each side one above the other ; and on the eleventh segment there is 

 one similar point on each side. Mr. Kiihn notes that the spots are some- 

 times greenish- brown.

Rober as P. ormenus, Guerin. Mr. Rothschild gives (b 2 ) : cf — ab. 

 pandion, Wallace, also (/ 8 ) : 9 — ab. polydorinus, Haase, also ( g 2 ) :

 to us from the Ke Archipelago. 



101. Papilio j;geus keianus, Rothschild. Plate I, Fig. 8, larva. 



Mr. Rothschild has described this local race from the Little Kei 

 Island (Kei Toeal) ; and also (a): 9 — f. amaranta, and (6): 9 — f. 

 blanca from the same island (Nov. Zool., vol. iii, p. 422, n. 4 (1896). 

 All our specimens appear to belong to this local race (not to P. ormenus, 

 Guerin), as in the males the discal white band ends on the first median 

 nervule, and does not reach the submedian nervure as it does in P. orme- 

 nus. In one of our male specimens the orange-red anal spot on the 

 hindwing on the upperside is absent, typically it is present, and Mr. 

 Rothschild has seen no specimen in which it is absent. It is rather rare 

 on Little and Great Ke. the female var. blanca especially so, and seen on 

 the wing only at the end of the wet season. The larva feeds on 

 orangeaceous trees. It is brownish -green, with lighter very fine lines
