and 0. Euplwrion : the abdomen is above of a dark fuscous 

 coloui" resembling" tliafc of the 0. EupJiorion and 0. Richmondia, 

 but dissimilar to the 0. Priamits, 0. Fronomus. and 0. Archideus. 



We trust that the distinctions we have pointed out are even 

 more than sufficient to constitute this fine example into a new 

 species, and we now proceed to enter more into detail. 



Length of wings, 7f inch in expanse. Upper surface of wings 

 (fig. 1, PI. 10) rich black brown, relieved by markings, but in a 

 lesser degree than any of its congeners. The primary — with 

 various patches and spots of impure white, principally running 

 obliquely ; three of these are placed in the discoidal cell, and one 

 in the disc immediately under, between the 2nd and 3rd median 

 nervules ; another, large and distinct, in each of the spaces 

 between the ord, 4th, and 5th sub-costal nervules ; two in each 

 space between the 5th sub-costal, and 1st and 2nd discoidal 

 nervules ; and a few small and indistinct spots running parallel 

 to the outer margin. The secondcij-y— possess three wedge 

 shaped markings of dusky white, becoming dull ochraceous 

 towards their outer margins, and bearing in their centres large 

 somewhat heart shaped spots of dark brown, which unite in the 

 disc with the median nervules. The sub-quadrate patch at the 

 anal angle, and a small triangular shaped one between the 2nd 

 sub-costal, and discoidal nervules, are of dull ochraceous colour, 

 whereas those situated near the anterior angle and between the 

 1st and 2nd sub-costal nervules are of brighter yellow. The 

 antennte, head, neck, and thorax, are dark black-brown, the 

 latter bearing a short central longitudinal band of metallic green, 

 while the pro-thorax on each side is edged with crimson. The 

 abdomen dark black-brown, becoming grayish towards the tip. 



The under surface (fig. 2, PL 10) is similarly marked to the 

 upper, but the white is purer, and a bright yellow replaces the 

 ochraceous tint : the margins of the large wedge shaped patches 

 are also here entitle. Each side of the thorax is clothed with 

 hairs of bright carmine, and the abdomen broadly barred with 

 yellow. 



The Ornithoptera Cassandra $ , is from the cabinet of Mr. 

 William MacLeay, Junr., and was captured at Port Denison ; 

 the male, we regret to say, is at present unknown.
