the veins placed between the submarginal and marginal series of 
spots are far more prominent than above, and reach the anal angle. 
This interesting dimorphic form appears to be the only one present 
in Basilan Island, trom whence I have four specimens and many 
males captured by Mr. W. Doherty. It is evidently a mimic of 
_ Danais (Radena) juventa, Cramer, which occurs commonly with it. 
Herr Fruhstorfer appears to have described it as an entirely new 
species.

The specimen here figured is in the collection of Mr. F, A, 
Moller, who has kindly lent it to me, and was obtained by his 
native collectors at or near Buxa in Bhutan. It is three parts 
male and one part female, the left-hand side being entirely 
masculine, as is also the right-hand forewing, while the right- 
hand hindwing is entirely feminine. The markings are quite 
normal for both sexes, and as usual the single feminine wing 
is much larger than the corresponding wing on the opposite side. 
The feminine character in the markings which immediately 
attracts attention is the disc of the hindwing on the underside 
which is marked with bright ochreous instead of violet as in 
the male. This is the only Asiatic monster known to me which 
is only one-fourth gynandromorphous, though bilateral and com- 
mingled specimens are occasionally found, the latter much less 
commonly than the former. 7
