the iiicdian vein. 'I'lio suliiiiarginal sjiots of llu- liiii(lwin<rs, ncarlv alwavs five in 

 number, are large; behind (he costal margin there stands a yellow sjiot of variable 

 size in many individuals, e^l)ecially often in specimens from the Solomon Islands. 



Below, the patch in the cell of the forewings has seldom disappeared. The 

 discocellular veinlets of the hindwings and the median nervure from the apex of the 

 cell to the origin of the lower median branch are black : the breadth of this black 

 nervnlar line is variable; in the more greeni.sh examjiles it is apparentiv thinner than 

 in darker bbie specimens. 



$. Resembles the female oi T. priamus ■poseidon (DouliL), but the wings are of 

 a jialer brownish colour, and the markings are smaller and more dusted with blackish 

 scales. 



The white patch in the cell of the forewings is generally smaller than in poseidon, 

 and sometimes obliterated above and below. The second submarginal spot of the 

 hindwings is often prolonged along the subcostal nervnie, as in T. ■priamus rich- 

 'inondius (Gray). Below, the markings of.the hindwings are sometimes yellowisli.

Green instead of blue, otherwise the same as urviUianus. 



This green form seems to be confined to New Britain and New Ireland. I am 

 told by Captain ^^'ebster that urvMiawua is green when emerging from the chrysalis, 

 and that it gradually assumes the blue colour. Individuals which are killed too soon 

 after the emergence from the pupae have that peculiar bluish green or greenish blue 

 colour which Pagenstecher mentions (^.c). In New Britain a number of specimens 

 remain green and have the appearance of T. pritimus poseidon (Doubl.); they are, 

 however, distinguished from the latter by the band along the inner margin of the 

 forewings above being more or less olisolete, by the median xein of the same wings 

 being covered with a few green scales only, or being quite black, and by the much 

 spai'ser gi'een scaling of the upperside of the hindwings. This green aberration must 

 certainly be accounted for by atavism. One of my six s[)ecimens has only one black 

 spot on the upperside of the hindwings. 



In New Britain (and New Irehmd Y) occuv feUKilcs which are identical with 

 T. pi'iarmis poseidon (DoxM.), except in being paler brown; these can very well be 

 mated with the green poseidmi-like mtiles.

 (9 ), one might be justified in regarding it as being only a local fiMin of thai species ;
