STAGES 
This insect was found to have five instars with four molting 
periods. The length of the first instar was about 20 hours, the 
second was about 24 hours, the third about 26 hours, the fourth 
about 30 hours, and the fifth about 35 hours. The range of life 
of the nymph was from 5 to 11 days. The period of birth was on 
an average two and a half minutes, and the period of molting ten 
‘minutes, 
Molting. The time required for molting was observed to be 
from 10 to 20 minutes. The skin divides at the head which is 
moved forward and forced out of the cast. The feet and an- 
tennae are released first, followed by the body, the cauda being 
the last portion to be extracted. 
First and Second Instars. The first and second instars of this 
insect are almost identical in form, except that in the second 
instar the body becomes somewhat enlarged and elliptical in 
shape, tapering to a rounded point at the cauda; while in the 
first stage nymph the lateral portions of the body are almost 
parallel with the head, and the cauda tapers abruptly. Eyes 
reddish. 7 
The second stage nymph soon after molting takes on a pea 
green color. The last two segments of the feet are a dusky color, 
and the last two joints of the antennae are also dark. The distal 
half of the cornicles are darkened, beginning at the tip, with 
a dusky area on body joining the cornicles. Eyes dark red. 
Cauda pea green with blackish tip. ‘The nymph moves about
