Though not recorded in the Twizell list, this is certain to 

 occur in Korth Northumberland. In the Morpeth district Mr. 

 Finlay found it generally distributed though not very abundant. 

 Mr. Henderson met with it at Jesmond, Mr. Bhagg also obtained 

 it in the same neighbourhood. Mr. Hedworth recorded it from 

 the Derwent district as generally distributed and fairly common 

 in the larval state. Mr. Maddison recorded it from Durham, Mr. 

 Greenwell and Mr. Ross as common on walls, etc., about Bishop 

 Auckland, and Dr. Lees found it in Upper Teesdale. It is com- 

 mon enough about Hartlepool in most of the woods and denes, 

 and plentiful in "West Hartlepool Cemetery. The larvae are seen 

 more frequently than the imago, and, like some others of the 

 genus, they appear very small for the size of the insect produced.

 scarcely ever been met with south of Yorkshire and Cheshire. 

 It is most numerous in Scotland, but occurs freely on the moors 

 of both these counties. The perfect insect sits on walls or 

 palings, but the bulk of our cabinet specimens are bred. It
