Generally common among oak, but I have few records. The 

 "Manual" gives it as abundant atbothNewcastle-on-Tyne and 

 Darlington. Mr. Finlay found it generally distributed around 

 Morpeth, and always common. Mr. Backhouse found it at St. 

 John's; it is very abundant in Hezleden Dene, where Mr. 

 Gardner has taken it freely.

I have no records for the occurrence of this insect in North- 

 umberland, and Meyrick limits its recorded range northwards 

 to Durham. Mr. Backhouse got it at St. John's ; the " Manual " 

 marks it as occurring regularly at Darlington, and Mr. Sang 

 appears to have taken it at several places around that town. In 

 August, 1860, he took it at street lamps. I have no other re- 

 cords. The larva feeds on willow and poplar, and I see no 

 reason why it should not be found in the more northern county. 



221. G. stramineella, Stain.

fpartimj. 

 Described by Stainton as distinct from elongella, but now re- 

 cognised as an uncommon variety of it. The only records I 

 have of its occurrence here are from the west of the county, 

 High Force, and Egglestone, where Mr. Sang took it in 1878 

 and 1879. His dates do not agree closely with those in the 

 "Manual," as he got it on 1st August, 1878, at High Force. 

 The Egglestone dates, 14th and 15th September, show the 

 ordinary time of the appearance of the second brood.
