CITALOGUE OF MOTHS. 139 



from this district is that Mr. Sang took it at Hell Kettles, near 

 Darlington, in August, 1881. He took one on the 6th and four 

 more subsequently, so that it was evidently a very scarce insect 

 there. Mr. Gardner took one at a brick pond near Hartlepool 

 some years ago. This pond is now filled up, but there are 

 plants of Spm^ganium in some of the ditches near.

A very common species generally, yet I have had no record 

 sent to me of its occurrence here, and the only notice of it in 

 our district is in the " Manual," where it is marked as occurring 

 at Newcastle-on-Tyne, and regularly at Darlington. I do not 

 think it is found in Scotland, yet it is singular that no one 

 appears to have met with it during the last half century. It 

 may be that it has left the district, but this seems very unlikely. 

 Can no one find it now ? The larva feeds on oak, beech, etc., 

 and the moth should be beaten from these.

A very local species, and, so far, not taken in Northumber- 

 land. Indeed I have but two localities in Durham, though 

 others are sure to be found when this group is collected. The 

 insect is not uncommon on the railway side, Hartlepool, and 

 Mr. Gardner tells me it also occurs on the banks of the Wear 

 at Chester-le-Street. The larva feeds in stems and roots of 

 Artemisia, and I expect where that is plentiful the insect will 

 be found.
