390 CATALOGUE OF MOTHS. 



It is difficult to explain the apparent almost total absence of 

 this common insect from these counties. Well distributed in 

 Yorkshire, it scarcely seems to occur here at all. Mr. Finlay 

 took one at Greenleighton ; Mr. Backhouse took one at Sliull ; 

 Mr. Greenwell sent me one to name that he had taken near 

 Bishop Auckland ; and I have taken one in nearly fifty years 

 collecting about Hartlepool. In contrast to this Mr. Gardner 

 says, "Black Halls, common in damp places, Teesdale common 

 in similar situations." I feel sure my friend is mistaken as to 

 Black Halls, and no one but himself appears to have met with 

 it in Teesdale.

 Though rather a common species, extending quite to the 

 North of Scotland, and often abundant where it is found, 

 Unidentaria (which Mr. Meyrick fuses with the last species) 

 does not appear to occur in these counties, the only 

 capture being one taken by Mr. Bolam. He says, *' This is 

 another good record, which, though I believe it is included 

 by Selby in his Twizell list, does not appear to have been 

 taken by any one else in the district, nor so far as I am aware 

 in Northumberland. My only specimen I took upon the wing 

 at Newham Bog on 25th May, 1893" (Trans. Ber. F. Club, 

 vol. XV., p. 302). The species is not included in the Twizell 

 list, and it is quite a puzzle to me why these common Coremia 

 are so nearly absent from this district.
