Tunis. From a much larger Mantis ootbeca, name and locality 

 at present unknown, I have bred four species of clialcids, 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 

 eggs in the middle of the ootheca is a problem well worth the 

 attention of anyone who may have the opportunity of observing it.
