is sometimes dentate npon the veins, more often indented, and also often separated 

 into spots or dots ; from none of our twenty-one males is the border entirely absent. 



?. The brown streaks of the forcwinjif are much more reduced than in the mnle, 

 but they are not absent from the outer-marginal region of the wing as in the ? of 

 orbona orbona ; in one hxw femnle the brown streaks are as well developed as in the 

 palest male of signijicans. The hiudwiug is either without indication of a black 

 outer border, or has a band of small marginal spots. On the underside the outer 

 region of the forewing is not quite so extended fuscous as in the male, the veins 

 traversing this area yellow ; mostly the fuscous colour is nearly or altogether 

 rej)laced by yellow ; there is always a black spot each at the costae of the fore- and 

 hindwing : these spots vary in size, but are generally much smaller than in the 

 mule.

S- Resembles orbona sig)ujicav.i very much, but the two patches of the upi)er- 

 side of the forewing are more distinctly white, being seldom somewhat tinged with 

 ochraceons ; the brown streaks, which are much more extended than the ochraceous 

 ones in all our specimens, are less dark fuscous, having an obvious yellow tint ; the 

 two yellow stripes upon and behind vein 2 are narrower than in (rrbona significans. 

 Tlie hindwing has mostly a narrow black border, cut by yellow veins {type), or is 

 uniform in colour ; the black border varies very much in extent, but does not seem 

 to become ever so broad as it sometimes is in signijwans. On the underside the 

 fuscous apical area of the forewing is traversed by yellow veins, and is less blackish 

 than in orbona siqnijicans; in a specimen from Mackay the fuscous colour is nearly 

 absent. The black costal spots are as in the New Guinea form. 



?. A specimen iu Dr. Standiuger's collection agrees with i\\e. females from 

 Fergusson Island, but has the brown colour in the middle of the forewing much less 

 broken up by the veins.

Though we. have not compared s])ecimeus from Goram Island, where the tifjie of 

 ochrealis came from, we believe we are right in identifying the Kei Islands specimens 

 with ochrealis. 



$. The variability is very great. There occur specimens which have the fore- 

 wing streaked brown, like the average specimen oK significans, and the two ochraceons 

 or whitish ochraceous patches well marked, while there are also specimens in which
