well. In the young state the bird is destitute of the scarlet orbits

5. Descriptions of some Butterflies from the Collection

Although differing greatly in size and colouring from the figures 

 of Cramer and Hiibner, I have no difficulty in believing that the 

 Butterflies here figured are varieties of the same species. 



The insects previously figured are from Amboyiia ; these are from 

 New Guinea, where, Mr. Wallace remarks, the Butterflies are gene- 

 rally smaller than those of Amboyna. 



The male of the Amboyna insect is without the white band of the 

 anterior wing ; the female has it. The male now figured seems to 

 represent the female of that insect. The upperside of the female 

 here differs but little from the underside of Cramer's figure of the 

 same sex. The undersides of both sexes of the Amboyna and New 

 Guinea Butterflies are nearly identical. 



I think it is not at all unlikely that the other figures in the plate, 

 which I have preferred at present to consider as a distinct species, 

 may be only another variety of D. Pandarus. 



The insects of this genus are well known to be subject to great 

 variation both in size and colour. D. Lasinassa has been figured 

 by Cramer alone under thirteen different names ; and I have no 

 doubt that P. Alimena, pi. 221, and P. Vitellia, pi. 349, both of 

 Cramer, are one and the same species.

Hah. Ke Islands, near New Guinea. 



All the insects of the plate are kindly lent to me from the private 

 collection of Mr. Wallace. 



Diadema Deois, Hewitson (PI. LIV. figs. 3, 4, 5). 



Upper side, male (fig. 4), dark brown. Anterior wing with an 

 indistinct transverse band of lighter brown beyond the middle. 

 Posterior wing with a large central rounded white spot, with, be- 

 tween it (touching it) and the anal angle, a rufous spot marked with 

 two black eye-like spots, each with a central dot of light blue, two 

 other indistinct black spots towards the costal margin touching the 

 central white, each with a scarcely seen dot of blue. 



Under side. Anterior whig as above, except that the central band 

 is nearly white, that the wing beyond it to the apex is lighter brown, 

 and that there is a black spot with a dot of blue near the anal angle.
