in the more common species, under wild conditions. 
If it does it must be very seldom as egg-cases collected 
out of doors have never given us any indication of 
such abnormalities as have been described in this note. 
Yet the fact that it occurs under the conditions we 
have described and that adults mav be bred from un- 
%j 
fertilized eggs without any artificial stimulation shows 
that the capacity for agamic reproduction has not 
been lost by the orthoptera, for it cannot be argued 
that this capacity is acquired as in the case of other 
orders where parthenogenesis is constant and regular. 
It may even be true that it is the constancy and the 
regularity which have been acquired in the higher 
orders and that the capacity for agamic reproduction 
has never been lost. 
There is still a great deal to be done and a wide 
field of properly planned experiments is open to sup¬ 
plement the haphazard observations here recorded.
