were running about fully formed this morning. I have been 
quite unable to see any legs such as Pagenstecher describes 
for the newly hatched young ; from the time previous to hatching 
the normal legs are well formed and there are no others. Nor 
can I satisfy myself that there is any real ecdysis between the 
pupa-like form and the active young ; at least, all that is-shed 
is apparently a thin egg-membrane, chitinized, however, over 
the head, forming a sort of cap to protect the bulging anterior 
end in emergence. Since this structure is developed in the 
egg, and shed immediately after emergence, should it not be 
regarded as an oval envelope ? 
In view of the above observations, it certainly seems desirable 
that those recorded for Mantis religiosa should be confirmed, 
as I can hardly believe them to be wholly correct. The spe- 
cies observed by me is a Stagmomantis, either S. caro/ina or 
S. limbata; I am not sure which, as both occur in the Mesilla 
Valley. 3
