I entirely agree with this statement and my only 
regret is that it is not likely that I shall ever have the 
opportunity of bringing up a sufficiently large 
number of these voracious beasts to settle the ques 
tion. 
Indeed we could never have carried out our ob 
servations on M. Savignyi without the assistance of 
the staff of the Military Infectious Diseases Hospital 
at Shubra, among whom I would especially mention 
Lt.-Col. G. Hall, Capt. T. Rankin and Capt. L. T. 
Burra, all of the R.A.M.G. These gentlemen kindly 
supplied us daily with live flies caught in Japanese 
fly-traps in the hospital and its dependencies, so that 
my sister was able to bring up a very large number 
of mantids and her unfailing care and patience made 
it possible for me to obtain accurate data concern¬ 
ing the life history of this species. I take this oppor¬ 
tunity of expressing to them my sincere thanks for 
the help they gave us and my gratitude for the kindly 
interest they showed in our work.

not been possible to work up the data obtained in 
this manner during the years 1916 and 1917.

in more northern latitudes have well-defined broods, 
are continuous breeders. Some of these are of eco-
