194 W. Doherfcy — The Butterjiies of Stmiha and Sambaioa, Sfc. [No. 2, 



veins is largest and broadest ; a slight diffused golden touch between 

 the upper and middle median veins, more distinct below. Below fore- 

 wing with the pale streaks whitish. Collar and patches at the base of 

 the wings red, abdomen mostly black except around the base of the 

 valves. 



Female, above dark brown, the pale streaks conspicuous, whitish, 

 occupying two-thirds of the cell, where they are broad with a conspicu- 

 ous streak in the middle. Hind wing with a golden area, slightly duller 

 than that of the male, occupying two-thirds of the cell transversely, and 

 six discal spaces from the subcostal to the fold above the submedian 

 vein ; a minute spot above the subcostal, the next area small, all of them 

 deeply incised outwardly; four pairs of triangular yellow spots are 

 usually on the outer disc, sometimes connected with the inner golden 

 area, by rays of the same colour ; there are a few marginal interner- 

 vular ochreous touches. Collar and base of wings red, abdomen laterally'- 

 and ventrally yellow with black spots. 



The outer margin of the hindwing of the male is remarkably 

 straight ; its expanse is nearly five and a half inches. 



The golden area of the male differs considerably from that of 0. 

 criton (Moluccas) and 0. plato (Timor). In plato the red patches are 

 wanting ; the female is unknown. In criton the female is altogether 

 different. The golden ai'ea is probably smaller in naias than in any 

 other species of Ornithoptera, except the Celebesian 0. haliphron, in 

 which the cell is all black. 



Common in Sumba, both on the coast and in the interior. 



In Samba wa occurs a variety (0. naias, var. sambavana), which is 

 considerably larger. The female has a large golden spot between the 

 costal and subcostal veins of the hindwing ; the outer discal pairs of 

 spots ai'e always connected with the central golden area, more or less 

 enclosing large black spots. In the male a golden spot (generally 

 present, though small in the Sumba form) between the upper and 

 middle median veins, is always absent, while in 0. criton, and presumably 

 in 0. plato, it is the largest of all.

Sumba, Sambawa. Both this and the Engano form resemble the 

 Javanese, which may and may not be the same as the typical Indian 

 one.
