678 Mr. G. F. Leigh on Synepigonie series of 
October 18 and 26, some of the larve lagging behind the 
others in their rate of growth. Another change is now 
witnessed ; for the larvee of the last stage are blue-green 
(exactly matching the food-plant), with small orange 
spiracular spots and two blue spots invariably present 
on the third segment, other segments being sometimes 
similarly marked. 
The larvze began to attach themselves preparatory to 
pupation on October 27, and continued to mature for 
about a fortnight. The situation generally selected was 
a part of the food-plant where a leaf had been eaten 
completely away; although some pupated upon the netting 
and some upon the sides of the tin, Six larvee were killed 
for preservation, and a certain number failed to pupate ; 
but I obtained 56 healthy chrysalides, all of which were 
green, exactly matching the shade of the leaves of the 
food-plant. 
The imagines began to emerge November 7, and con- 
tinued to come out up to the 22nd. 
It is often stated that the males of Lepidoptera tend to 
emerge before the females, a conclusion which my experi- 
ence by no means confirms. In this case the first two 
which emerged were both females. I did not keep an 
account of the emergences after this, but the largest 
number to appear in one day was 11, of which 7 were 
females. According to my usual experience with bred 
specimens there were a larger number of females than 
males, viz. 27 to 18. The 11 remaining pupe either dried 
up or produced cripples.* 
All the specimens were smaller than those of the same 
broods captured in the wild state, and this I trace to the 
artificial conditions inseparable from the described method 
of breeding. 
In nature the females are far rarer than the males; one 
might probably see twenty-five of the latter to one of the 
former. ‘The female, I believe, flies but little in the open 
except when engaged in oviposition. Only two or three 
eggs are laid on each plant, and those growing under trees 
or otherwise in the shade are the most frequented. The 
* In future work of this kind when the material bears upon 
problems in heredity of the utmost importance and complexity, 
every dead pupa and every crippled specimen should be carefully 
preserved ; for the lens would certainly reveal the sex, while dissection 
would in many cases reveal the variety.—E. B. P,
