Records observations, extending over two years, on the life
histories of A. tessellata and E. tiaratum bred in captivity
from eggs laid in the laboratory in January, 1959, by mated females.
In both species the incubation period ranged from eight to twenty months.
In the development of both male and female A. tessellata
each of the six nymphal stadia was approximately fourteen days.
For E. tiaratum there were six nymphal stadia for the female,
and five for the male. In the case of females of E. tiaratum
bred from eggs with an incubation of eight and nineteen months, the
duration of each stadium was approximately nineteen days and twenty-four
days respectively. Male nymphal stadia were slightly longer than those
of the female.
