428 Mr. W. J. Kaye’s Notes on the dominant Miillerian 
localities even as close as Venezuela and Trinidad Z. ceres 
occurs, and never shows the deep black colour on the 
hind-wing, while Z. pasinuntia has its home almost 
confined to Guiana and yet does not conform to the local 
influence to so great an extent nor in such a large pro- 
portion of the specimens. Both species occur chiefly in 
the long dry season which usually sets in at the end of 
August and lasts up to nearly the close of December, but 
odd specimens may be turned up at most times of the 
year, and I personally took several of each in May 1901, 
when the rainy season had begun in earnest a month 
previously. : 
As has already been seen with the Ithomiines the 
darkening of the hind-wing is far more pronounced on the 
upper-side, in fact on the under-side there is always a well 
detined area where the dark scales fail to obliterate the 
band. Tabulated, Lycorea ceres works out thus :— 
Lycorea ceres. UPPER-SIDE. UNDER-SIDE. 
Hind-wing distinctly banded 6 = 30% 18 = 90 % 
Hind-wing obscurely banded 12) 60/7 2— OR 
Hind-wing band obliterated PAO OS 
20 20 | 
We thus find that on the upper-side the specimens with 
a wholly and partially obscured band number 70 7%, while 
on the under-side they only number 10 as while the banded 
forms claim no less than 90 /, an almost complete reversal 
of the one to the other. 
That this species should vary so in regard to the 
colouring of the hind-wing is not to be surprised at, but it 
is very remarkable that the pattern of the fore-wing 
should remain so constant, as there is never any tendency 
to the form atergatis, such as is so frequently met with in 
Trinidad, nor is there any tendency to darkening of the 
fore-wing, such as is frequent in Peru, proving by the 
latter case that the species is in no need of adopting a 
more uniformly dark aspect, even though it is able under 
certain conditions to do so. The interest centring round 
Lycorea ceres must always be considerable. It is a species 
that occurs in one or other of its forms throughout nearly
