DESCRIPTIONS OF FIVE NEW DERMAPTERA. 

 BT MALCOLM BUER, B.A., P.L.S., F.Z.S., F.E.S. 



A large number of new earwigs in the National Collection of the 

 Paris Museum have been described by me in an earlier paper (Trans. 

 Ent. Soe. London, 1904, p. 277), but since the appearance of that 

 article I have come across a few further novelties, which are described 

 here in order to be able to quote the species in the final list of the 

 collection. I have added a new species from Java, from among a 

 number of earwigs received for determination from the Amsterdam 

 Museum.

Allied to Gh. fece, Borm., but the form of the pronotum is 

 characteristic; in the shape of the forceps and pygidium it is 

 nearest to Ch.fece.
