 Geo. Ross; ''Rare in woods about Eishop Auckland," J. 

 Greenwell ; '' Darlington, gardens, etc.," W. Backhouse. 

 Darlington is also a ''Manual" locality. About Hartlepool 

 Bidentata is much less frequent than it was twenty or thirty 

 years ago. A fine form, with the space between the lines, 

 much darker than the other portions of the wings occurs 

 occasionally, and I took one on 4th June, 1900, in Hezleden 

 Dene, that is all dark brown, with only traces of the lines.

 accidental omission, as it is certain to occur there and there-

 common ; more than seventy years ago Mr. Ilewitson reported 

 it from Newcastle (Steph. Illust., vol. iii , p. 62), and it is still 

 plentiful all round the city ; Miss Rosie reported it from Xenton, 

 her brother from Dinnington and Stocksfield ; Mr. W. Patterson 

 from Jesmond Dene, around where Mr. Sticks found it fairly 

 common at light. He also found larva sparingly in the Derwent 

 Valley, and Mr. Hedworth took the species commonly through- 

 out that district. "A single specimen taken in a gas lamp at 

 South Shields" was deemed important enough to be recorded in 

 the Transactions of the Society (vol. v., p. 287), but more 

 recently Mr. Stephenson reports it as fairly common there. At
