234 I.EPIDOPTERA. 



almost limited to the casual specimens which at rare in- 

 tervals were disturbed from among the sedges by the footstep, 

 or by the scythe of the mower ; though Mr. F. Bond is said 

 to have taken specimens at one time at sugar ; and a very 

 few have been noticed to fly at sunset in especially favourable 

 weather. But in the year 1871 Dr. F. D. Wheeler commenced 

 to use powerful movable lamps, for the attraction of moths 

 at night, in Wicken Fen, and in that year took twenty-one 

 specimens. From that time to the present the same method 

 of capture has been used with success, and it has become 

 evident that though so seldom seen, the insect must have 

 long been common in this fen. It was formerly taken, 

 though rarely, at Yaxley and in other Cambridgeshire fens, 

 and has been found quite near to Cambridge ; but it has, so 

 far as I know, no other haunt in these Islands. Abroad it is 

 found in France, Piedmont, Germany, Lower Austria, and 

 Livonia, and is reported from Tartary.
