as the ordinary scales, the white ones are smaller, again 
similar to those in the primaries, but they are depressed and 
below the usual level, whilst the grey androconia are in a small 
pit, and I imagine that the main part of the tuft of hair-like 
scales in the primaries lies in this androconial pit. There is 
in addition to this the long tuft of hairs risingin the fold between 
veins la and the cell, its base is covered by ordinary scales, 
but on the denuded membrane is seen a short ridge which is 
no doubt the source of this tuft, the scales underneath this 
seem to be but little displaced by its presence. The membrane 
itself is only changed in the androconial area and to some 
extent in the surrounding area occupied by the white scales; 
it is a hollowed pit, and from the points of attachment shows 
the enormous number of minute scales that must be crowded 
in so small a space. 
In Dioptes catalla we find the tuft in the primaries to be so 
similar to that in Deudorix camerona as not to need further 
mention, but the androconial patch on the secondaries is 
quite different; it is interesting to find that all the scales 
immediately surrounding the brand sweep round from the 
horizontal position with apices facing up to it: the brand itself 
is composed of probably thousands of minute erect scales, 
very long in proportion to their breadth, of almost equal 
width throughout, and having rounded apices, and packed 
together as tightly as possible, not flat but vertically from the 
membrane; this alters the whole wing below it, even the under- 
surface, for there is apparently a bare patch in that spot 
on the underside; when carefully examined however it is 
found to be covered with neutral grey scales which are quite 
transparent, and when viewed under transmitted light are 
quite colourless; the patch is quite peculiar, having much the 
outline of a full blown rose. The brands of the Indian species 
of the genus Rapala are very closely allied to Dioptes so far 
as the patch in the secondaries is concerned, though they differ 
somewhat in the primaries; in petosoris there is so to speak a 
double tuft of hairs the larger of which has its origin on vein 
la, emitting a small and short little fringe upwards just over 
the vein, but sending all the long hair-like scales downwards 
to the inner margin (whilst another less copious one ascends
