Closely allied to Prosthesima nigrita, Fabr., but larger, and 

 differs in the structure of the genital aperture. An adult 

 female, found at Dunmore in Scotland, was received in 1878

 examples, which I believe to be also of this species, were 

 received some years ago from Mr. W. Farren, by whom they 

 were found in Wicken Fen, Cambridgeshire.
