Tunis. From a much larger Mantis ootheca, name and locality 
at present unknown, I have bred four species of chalcids, three 
of which, possibly hyper-parasites, are very small and have no 
long ovipositor. The way in which these are able to get to the 
egos in the middle of the ootheca is a problem well worth the 
attention of anyone who may have the opportunity of observing it.
