Sang took the insect first at Hell Kettles near Darlington, on 

 8th October, 1879. Next year he found the larvse there on 

 17th June, and on 29th September he again took the perfect 

 insect. I have no other record.

An abundant insect everywhere. The larva feeds on many 

 trees, but appears to have a preference for birch, and wherever 

 there is plenty, Solandriana is common. Mr. Finlay says 

 abundant among birch in July and August. Mr. Maling also 

 recorded it in the Transactions for 1875 (p. 281). Sang found 

 it at High Force in July, 1873, and elsewhere. It is abundant 

 in Hezleden and Castle Eden Denes, and at Edder Acres, near 

 Thornley.

Bather a local species, and commoner in the south than the 

 north. Meyrick indeed limits its range to York, but that is far 

 wrong, for Mr. Einlay found it among poplars on Needless Hall 

 Moor. Mr. Sang found it in Castle Eden Dene in September, 

 1862. He afterwards showed me the place, a group of black 

 poplars, not very far from the mouth of the dene. "We took a 

 good many of the moths flying round the trees in the afternoon 

 sun. Meyrick gives aspen as the food {Populus tremula), but 

 they certainly fed on Populus nigra in Castle Eden Dene. Mr. 

 Gardner subsequently bred it from larvae found on the same 

 tree nearer Hartlepool.
