sand or else turn the forceps over their hack in a very threatening 

 attitude. _ The stones they seem to prefer to hide under arc the flat 

 ones resting upon the fine sand, and under them they often make a 

 pit in which to rest. I generally found one under a stone, although 

 sometimes there were two; but under a piece of lino, about 2 yards 

 by 1 yard, that I turned over, I counted a large number of adults and 

 nymphs. The thing that puzzled me was what they could find to 

 feed upon ; there were no plants or seaweed near where they were 

 found, nor were there fish of any kind. The only tilings l" found 

 were some beetle larvae, like wire-worms, about \ in. long, that live 

 in the sand. Some earwigs that I brought home alive have eaten 

 these larvae very readily. They have also eaten raw beef ; but they 

 seem to like best living house-flies. These they chase and catch, 

 using their forceps to hold their prey whilst they feed. They also 

 use the forceps for carrying the flies about if they are disturbed while 

 feeding. I hope to be able to keep some alive and discover at what 

 period of the year they oviposit, and if the female is as attentive to 

 the ova as is that of the common earwig, Forficula auricularia,
