O. marinus, Payk 



I have specimens of O. viridis in my collection taken by Mr. 

 W. H. Bennett at Pett, Sussex, which have been named by M. Sainte 

 Claire Deville. The specimens standing as O. man/ipallens in the 

 Power collection labelled " Baiuhani " must be referred to O. viridis, 

 and possibly also those from Gravesend. 



It should be remarked that; the deseri|)tion of H. angustata in 

 " i-'owler's British Coleoptera " applies much better to that species than 

 to E. longior, while his descri[)tion of O. marf/ipallens is much more 

 applicable to O. viridis.

A NEW BRFlTStl EARWIG? 

 BY MALCOLM BURE, F.L.S., F.O.S., F.E S. 



In the Ent. Record, vol xv, p. 254, 1908, I recorded two female 

 specimens of Forjicula nnricularia, Linn., taken in horse-dung at 

 Compton Bay, near Freshwater, in the Isle of Wight. These two 

 specimens are remarkable in that the wings are abortive and the 

 elytra are truncate. 



I have since examined these specimens again, and have compared 

 them with fresh examples of females of ForJiGula decipiem, Gene, 

 from Italy, and I can find no difference.
