Harpella bracteella. 'I'his species was recorded as 

 British in the E. W. I. (iii. 179) from 

 specimens taken and bred at Shotlcy near 

 Gateshead, and I took a beautiful specimen 

 at light near Throston,Hartkpool\n June I 880. 

 It is therefore widely spread in the county, 

 but not enough is known of its habits for it 

 to be often taken. I believe less than a 

 dozen British specimens exist, all from 

 Durham but one. The larva feeds on rotten 

 wood
