 By II. Grose-Smith, B.A., F.E.S., F.Z.S., &c. 



Ornithoptera litany sp. n. 



c? . — TJpperside. Anterior wings black, with a broad 

 yellowish-green band extending along the costa and partly 

 invading the cell, narrowest at the base, but becoming wider 

 in the middle and tapering towards the apex, which it does 

 not reach ; on the disk from the base and thence below the 

 median nervure to the inner margin is a yellowish-green 

 triangular area, the apex of" which is a little above the lowest 

 discoidal nervule ; this green area, between the median ner- 

 vules, does not extend to the median nervure, nor does it 

 reach the outer margin, which is broadly black ; there is no 

 stigraatic brand as in the 0. ^rmw? us group. Posterior wings 

 golden yellow, with a black outer border, which is narrow 

 along the costa and becomes wider at the apex ; the outer 

 edge of the yellow area is golden green, which colour extends 

 inwardly along the veins; beyond the yellow area, which 

 extends rather beyond the lowest median nervule, to tlie inner 

 margin the wings are jet-black, the abdominal fold, which is 

 bordered basally by golden scales, being very wide; on the 

 disk towards the apex in the yellow area between the veins 

 are three large oval golden-green patches, in the upper part of 

 each of which is a black spot, which represent the spots on 

 the underside. 



Underside. Anterior wings golden green, the costal, outer, 

 and inner margins broadly black, the veins black; on the 

 disk between the veins is a row of four rather narrow black 

 lunules. Posterior wings golden yellow, with a golden green 

 submarginal and inner-marginal area, the latter very wide ; 

 three large oval black spots on the disk, the uppermost sub- 

 apical, the two others on either side of the lowest subcostal 

 nervule ; outer margin nairowly black ; abdominal fold pale 

 buff, with long hairs of the same colour. 



In shape the anterior wings are very broad, less produced 

 at the apex than in the 0.j9ria7??Ms group ; posterior wings 

 convex and rather truncate at the anal angle. Antennae, 

 thorax, and legs black ; abdomen yellow, with small black 

 spots on either side ; orbits white. 



Expanse of wings 7| inches.
