Hah. — Bouru, Amboyna, Ceram, Goram, Ke Islands, 

 Waigiou, New Guinea. (Wallace) . 



This species varies much, and the sexes generally 

 differ greatly, but there are intermediate forms which 

 connect the whole into an unbroken series. P. Porphyria 

 and P. Velleda of Cramer, have usually been placed with 

 Diadema Lasinassa, but they agree very closely with 

 some of my specimens of this species. 



4. Diadema Polymena.

Hah. — Aru Islands (Felder) . 



This is an extreme form of Diadema Alimena, the 

 female assuming the white colour which characterizes 

 many butterflies of different genera in the islands south- 

 east of Coram.

Hah. — Amboyna, Coram (Wallace) . 



The female has the band across the upper wings either 

 creamy white or pale rufous ; the former appearing to be 

 characteristic of Amboyna, the latter of Coram. 



6, Diadema Pandora, n. s. 



Female. Wings rather more elongate than in D. Pan- 

 darus, the posterior margin more deeply scallopped. 



Above; the band on the anterior wings replaced by 

 four spots, the lower and upper of which are small, the 

 two middle larger, white, tinged with ashy violet; the 

 row of white spots parallel to the margin smaller and of 

 a subquadrate form; the submarginal lunules nearly 

 half-square instead of triangular. Posterior wings with 

 the black spots almost circular, the pupils almost ob- 

 solete.
