poh/les and poh/tes theseus in being (in individnals of equal size) larger (f. 22 and 

 23); the angles of the blade are less prominent than in poh/tes polijtes, hy which 

 character it leads over to P. pohjtes theseus (f. "^'s). 



c. P. polytes nikoharus from the Nicobars and Andamans ; f. 27. 



We have now received more material from these islands, and find that polytes 

 nikoharus can very well be kept separate from poh/tes polytes, as the greater pro- 

 portion of the specimens from the Andaman and Nicobar Islands are somewhat 

 different from /joh/tes polyti'S. The harpe confirms tliis ojiinion ; the outline of its 

 blade is more rounded (f. 27), not exhibiting the two angles found in polytes polytes 

 (f. 18), and resembles somewhat that of P. polytes theseus from Java (f. 29), except 

 in the apex being obviously truncate. 



d. P. polytes theseus from the larger and lesser Sunda Islands ; f. 28 to :W. 

 This subspecies differs in the male from P. polytes polytes in being generally 



smaller and in having the tail to the hindwing more or less obliterated. The harpe 

 of /'. polytes theseus is distinguished from that of polytes polytes by being in the 

 blade absolutely longer, less raised, much more evenly rounded, and by the aj)ex 

 being more pointed. 



Sumatra and Borneo individuals have the blade shorter and higher than Java 

 examples, and hence lead over to polytes polytes ; f. 28 is talceu from a small 

 examj)le from the Kina Balu (North Borneo). Timor specimens agree generallv 

 with the Javan individuals in the form of the harpe; f 30, however, is aberrant 

 in having the second angle of the edge of the blade faintly marked and the apex 

 distinctly truncate in a ventral view. 



e. P. polytes alcindor from Celeljes and Saleyer: f. 34. 



1\\e. female of this subspecies is very aberrant, the vinle much less so. Tiie 

 male bas one character in common with P. polytes polytes and P. polytes theseus, 

 namely the presence of bine scales on the underside of the hindwing outside the 

 macular white band, which scales are absent from the subspecies flying on the 

 Philippine and Moluccan Islands. So insignificant as this cliaracter is, it becomes 

 interesting wlien we see that the harpe of polytes alcindor (f. 3-t) comes closer in 

 outline to that of polytes polytes (compare f. 25) than to that of jwlytes alphenor 

 from the Sulla Islands (f. 33) or from the Philippines (f 32). We observe, however, 

 that the tip of harpe of polytes alcindor (f. 34), though short, is visibly curved 

 upwards in a similar way as in polytes ul/ihenor. 



f P. polytes permrsus from the islands of Sangir and Talaut; 1. 35. 



In external features this form combines to a certain extent in the male the 

 characters of polytes alcindor (Celebes) and polytes nicanor (Halmaheira). The 

 harpe comes nearest to that of alcindor; has the tip, however, a little more hook- 

 shai)ed. 



g. P. polytes a//;/iC/«3r from the Philippine Islands (inclusive of Palawan), tlie 

 Sulla Islands, and the Southern Moluccas; f 31 to 33. 



The males from tliese various islands agree very well with one another in 

 external characters ; the \^o\ymovii\\\c females, however, are partly different accord- 

 ing to locality, thus showing that the insect is on the way to develop into several 

 local races. The harpes of the males are, according to locality, slightly diflerent.
