* Pterophorus paludum Ze//. I was much astonished to 

 take a very fine specimen of this species (hitherto only 

 known as British from the Cambridgeshire Fens, and a 

 restricted area in Dorsetshire), right on the open part of 

 Thorne Moor, on July i8th, 1891. The determination 

 has been confirmed by Mr. C. G. Barrett and Mr. 

 Sydney Webb (see Ent. Mo. Mag., October 1891, p. 

 275, and Nat., October 1891, p. 312). Since then I 

 believe Mr. John Harrison, of Barnsley, has taken 

 another specimen on the same ground.
