monticola; for although Stainton himself, after describing it 

 (I.e.) as alpi7ieUa, subsequently sunk it, in the index to the 

 "Manual" (ii., 472), as a variety of Tiilmunella, he was in 

 error in doing so.

Eather a common species generally, but I have few notices 



of its appearance here. Mr. Hodgkinson took it in West 



Northumberland, the only record from the county. The 



"Manual" gives it as being abundant at Darlington — too 



common probably for Sang to enter in his diary. The only 



other records I have are that Mr. Gardner has taken it in 



Hezleden Dene and nearer Hartlepool, and that it has been 



captured at Sunderland by Mr. Corder. It is probably common 



in both counties. The larva feeds in several grasses.

This was introduced as a new species in the Entomologist's 



Annual for 1855, having been reared from the larva by Mr. 



C. S. Gregson ; however Mr. Bankes informs me that the 



imaginal and larval differences pointed out by Mr. Stainton 



between gregsoni and nigrella are held to be unreliable, and 



that they are now considered to be one and the same species. 



But I enter gregsoni separately, keeping to my rule to follow 



Stainton in all such cases. Mr. Sang took it " flying in the 



sun, 3 to 4 p.m., in Coniscliffe Lane," on May 15th, 1872; he 



took it again at Hell Kettles, and the next year he found the 



larvae there, April 5th to 19th, 1873. In 1877 he found larvae 



in Coniscliffe Lane on April 3rd, and the following year he got 



it again, but earlier, March 1st to 17th.
