116 CATALOGUE OF MOTHS. 



An autumn species, well distributed and not uncommon. It 

 is in the Twizell list ; Mr. Finlay took it at Coal Law "Wood 

 and at Throphill Moor, generally most abundant at Heather 

 Blossom. Mr. Ehagg met with it at Allendale ; Mr. Hed worth 

 got it at sugar at Thornley and Dunston ; Mr. Backhouse at 

 ShuU ; Mr. Maddison at Durham ; Dr. Lees found it common in 

 Upper Teesdale ; at Bishop Auckland Mr. Boss took a single 

 specimen ; Mr. Sang took it at Bagwort flowers in August, 1858. 

 I took two or three at Bagwort in September, 1874, on our sand- 

 hills, and again in 1876, but I have not seen it there since. It 

 is not very rare, however, about Hezleden Dene, where I took 

 several at sugar in 1897. Only the type occurs with us.

An abundant species every where, plentiful on the coast sand- 

 hills, as well as on some, at least, of the moors, and marked as 

 plentiful in all the lists. Though a very constant species, some 

 curious aberrations of the insect have been met with, but not in 

 our district.

One of the commonest species, occurring abundantly every 



where. I have occasionally taken at Hartlepool examples in 



which the pale costal streak was suffused and obscured with
