of several scales which fail to meet at the tip; outer rim of the cap flat with minute, 
regular reticulations; extension of the chorion on the same plane with the outer 
rim of the cap in new laid eggs, after hatching or drying bending upwards or down¬ 
wards, squamous, minutely so towards the inner border, gradually coarser outwards, 
edge sinuate; chorial processes numerous, elongate, club-shaped, within the exten¬ 
sion of the chorion.” 
When the egg leaves the body of the female the fringe-like collar is 
folded up with the scales erect as is the bud of a flower, and forms a 
button-like knob on the top of the egg. Upon drying, however, the 
collar expands and takes a horizontal position as described above. 
This process of expansion, at least under the heat of a microscope lamp, 
requires less than a minute. 
Hatching: In from ten to fourteen days after being laid the eggs 
hatch. Stages in incubation and appearance of eye spots can not be 
seen because of the opaque shell. 
In hatching, the insect tilts the cap off and emerges slowly, requiring 
about two minutes for the operation. The young insect appears to be 
folded once upon itself and the top of the thorax appears first. The 
membrane of the post-natal molt is broken through and the body and 
appendages slowly freed. The legs, antennae and beak are folded up 
together and are extricated by repeated pulls, first on the hind legs, 
then the middle legs, then the front legs and finally the antennae. At 
each pull a slight advantage is gained. When nearly cleared, the 
appendages are bowed out to the sides and a little additional leverage 
gained in this way. The short, middle legs are freed first, the hind 
legs next, and the long front legs and antennae last. When the append¬ 
ages are all free the insect remains for a short time attached to the shell 
by the tip of the abdomen only, apparently waiting for the legs to be¬ 
come hard enough for use. Then it catches hold with its legs, easily 
frees the abdomen from the post-natal membrane, and stalks off. 
The cap of the egg frequently catches on one of the spines on the 
thorax and adds something to the already grotesque appearance. 
Feeding of Nymphs: After hatching, the nymphs were isolated in 
stender dishes, given a bit of stick to rest on, and fed daily. The 
smaller nymphs were fed plant lice, tender leaf hopper nymphs and very 
small caterpillars. Older nymphs were fed adult leaf hoppers, larger 
caterpillars, mirids, and various other insects. It was observed that 
ants and lady bird beetles were not attacked if there were other insects 
present that could be fed on. The nymphs, and adults as well, were 
canabalistic to a certain degree, but they seemed to prefer other species 
when they could get them.
