On new Indo-Malayan Lepidoptera. 407 
gradations between them, just as we have seen to be the 
case in the Eocene species, and, as pointed out at the he- 
ginning of this article, long known in many Jurassic species 
also. The objection, therefore, had it been considered 
sound, might have been raised many years ago; but the 
facts are much what we might expect on any hypothesis of 
the origin of Balunocrinus from Isocrinus, and are certainly 
consistent with the special hypothesis here advocated of the 
multiple origin of Lalanocrinus from successive species or 
species-groups of Isocrinus. It may be impossible to assign 
an isolated ossicle to its correct genus, but the stem must be 
considered as a whole. 
Admitting the polyphyletic origin of the genus Balano- 
crinus as hitherto conceived, our future task is to divide it 
into sections, each of which may be regarded as a subgenus 
of Isocrinus if not as a full genus.~ One such section will 
undoubtedly comprise the forms herein discussed. In that 
event the validity of Balanocrinus itself will not be settled 
by the variations or growth-stages of this Cretaceo-Tertiary 
assemblage, but by the relationships of the genotype, the 
Oxfordian Balanocrinus subteres; and “that is another 
story.”

3. Upperside dark olive-brown, the outer margins paler 
and somewhat ochreous-tinted: fore wing with a rather large 
and round bluish spot below the middle of vein 2, with a 
smaller one immediately below it and seven submarginal 
bluish spots decreasing in size from the apex downwards : 
hind wing with the costal space pale ; a large ochreous-grey 
patch covering the upper half of the cell and a space above 
it, a postdiscal row of obscure dots and another submarginal, 
the uppermost one most pronounced. Underside: fore wing 
coloured as above ; a very large ochreous-grey hinder mar- 
ginal space which extends to the median vein and a little 
beyond vein 2; a large round ochreous-grey spot below 
vein 3 near its base, a small one above it, and a whorl of four
