which occurred during the periods of this study (June 25-August 8, 
1956, and June 19-July 18, 1958). 
Color notes were made from microscopic observations of living 
larvae and these were supplemented by color photographs taken of 
freshly killed larvae. The drawings of Plates 5 and 6 were pre- 
pared by the author from these notes, from material fixed in Peter- 
son’s KAAD fluid (see Peterson, 1953, for details of preparation) 
and stored in alcohol, and from the examination of cleared specimens 
in temporary glycerine mounts with a binocular dissecting microscope 
and with a phase-contrast compound microscope. All measurements 
were made with an ocular micrometer calibrated with a stage mi- 
crometer. All indices of dispersion given in this paper are standard 
errors of the mean. 
Description of The Developmental Stages 
Oviposition and embryonic development — The three females used 
in this study were confined for periods of nine, fifteen and twenty-two 
days, during which times a total of ninety-four eggs was deposited. 
These were produced in a series of small lots which, with one excep- 
tion, contained between one and eight eggs (x = 3.53 ± 0.53 eggs/ 
lot). In a single instance a freshly caught female, whose abdomen 
was noted to be tremendously swollen with eggs, laid twenty-seven 
eggs during her first twenty-four hours of confinement. Subsequent 
to this, however, the egg production of this female fell within the 
limits noted above. In all cases oviposition occurred at night and 
was never observed by the writer. 
In addition to the ninety-four eggs produced by these females, 
the remains of an undetermined number of other eggs were noted 
which had, apparently, been partially consumed by the females. Six 
of the ninety-four eggs regarded as normal may also have been dam- 
aged by one of the females as these were slightly distorted in shape 
when first seen and none of them showed any signs of embryonic 
development. Three additional eggs although seemingly normal in 
all respects also failed to show any indication of development. Of 
the eighty-five eggs which showed apparent normal development, two 
failed to hatch.

surface attached to substratum. Color, a pale greyish-yellow, becom-
