varying in the latter from being entirely yellow to being above as black as in 

 cimeifer : in the specimens with the brownish black upperside of the abdomen the 

 sides of the aljdomen are of the same greenish yellow colouras in cuneifer. 



Thus there remain only the somewhat browner colour of the forewings, the 

 gi-eener tint of the hindwings, and the broader black band along the discal side of 

 the abdominal fold of the hindwings, by which cuneifer i is distinguished from 

 (imphri/sus and its local forms. I must add that the hindwings of cuneifer are of 

 a different shape, being less rounded in the anal region than in most aniphrysiis, 

 that the scent-organ within the abdominal fold is rather whiter than in (imphrijsuf, 

 and that the hind femora are black. 



?. In the female, however, there is not a single character by which all the 

 specimens of cuneifer can be differentiated from all the specimens of amphrysus. 

 In most (not in all) individuals of cuneifer the markings of the forewings, chiefly 

 those towards the hinder angle, are more yellowish, and the yellow region of the 

 hindwings is less yellow towards the base and beyond the cell.

The collar of this subspecies is either yellow or red ; the yellow-collared form is 

 confined to Borneo and the adjacent small islands, where it flies together with the 

 red-collared form, and is nothing but a local aberration. As, however, the name of 

 flavicollis (Druce) has the prioiity' over the name oi ruji colli s (Butl.), we must apply 

 that name to the subspecies; the name of fldvicollis includes therefore the red- and 

 yellow-coUared specimens. There occur e.xamples in which tlie collar is vellowish 

 red, and this proves that the colour of the collar is of no .specific value. 



cJ. The black border of the hindwings is obviously narrower than in ainp>hrysus 

 (Cram.) ; the yellowish markings of the forewings are restricted to the marginal 

 region of the wing in most individuals, and seldom occupy so much of the apex of 

 the cell as in amphrysus ; below, they are decidedly whiter than in the Java insect. 



?. Often scarcely or not di.stinguishable from amjjhrysus (Cram.); the white 

 patch at the apex of the cell of the forewings is more triangular, being more extended 

 along the subcostal than the median nervure ; in many individuals the white colour 

 is much increased on the forewings. The hindwings are less whitish towards the 

 base and lieyond the cell ; the yellow spot between the costal and subcostal nervures 

 is often larger than in amphrysus, especially in individuals with pale foi-ewings.
