S- P'orewings uniformly lilack above and Ijelow, darker than in ohloiujoniuculatus 

 (ftoeze). Cellular yellow .spot of the hindwings usually larger than in the typical 

 race, more obliquely cut off basally. Yellow spot before the .subcostal vein absent 

 or very small; that behind the cell longer than in oblongomaculatus. 



The black colour of the costal and basal portion of the liindwings penetrates 

 often only a little into the cell. Mostly the black colour of the cell is limited 

 obliquely, the bordering line having the direction of the subcostal nervule; sometimes, 

 however, only the apical half of the cell is yellow. The yellow mark between the 

 abdominal fold and the cell extends mostly to the base of the wing. 



?. The yellow area of the hindwings is of almost as deep a yellow colour as in 

 the male. The subdiscal black spots of the hindwings are small, and in many 

 individuals completely merged together with the marginal black border ; cellular 

 yellow spot more obliquely cut off basally than in oblongomaenljUus ; postcellular 

 yellow mark shaped as in the male, but longer and broader. Abdomen yellow below, 

 with a series of black spots on each side; in oblongomaculatus ? the imderside of 

 the abdomen is black, with the edges of the segments and the middle of the posterior 

 ones 3'ellow. 



The forewings are either black above and below, as in the male, or there appear 

 whitish streaks along the nervules, first on the underside, then also above. The 

 yellow area of the hindwings is seldom of the same yellow colour on both sides of the 

 wings; in mo.st specimens it has on the underside the pale buflSsh tint as in ohlovr/o- 

 maoulatus, especially so in the individuals with paler forewings.

Mr. Oberthiir kindly gave us a sketch of his papuanus, and T must state (hat 

 piijmanus lielongs to papuensh (\\'all.), not to criton (Feld.). 



The adnervular whitish streaks of the forewings in the region of tie end of 

 the cell are large and united in pairs at their bases ; apical third of the cell also 

 white. Hindwings with small, subdiscal, black spots, which are joined to tiie black 

 border or stand separate, or with a simi)le, very broad, black border to the outer 

 margin. 



This form of i\\f female is connected with the black form by every intergradation. 

 In all the yellow Troides (Aviphrisins Swainson) there occur two forms of the fern ate 

 sex, one with darker, the other with lighter forewings. 



Hab. New Guinea (11 <S, 14 ?). 



Occurs all over New Guinea (I have examples from Kedscar Hay, British New 

 Guinea), but is apparently locally rather scarce.
