226 CATALOQTJE OF MOTHS. 



by the late George Wailes, who also supplied lists to Stephens' 

 Illustrations. As the occurrence of this species is not named 

 in the Illustrations, Mr. Wailes, if he were Stainton's authority, 

 must have found it subsequently to 1829, when Stephens' 

 vol. iii. was published. The only recent capture that I know of 

 is that Mr. D. Eosie took one at Fenham. It should be care- 

 fully looked for by the IS'ewcastle collectors, and will I hope be 

 turned up by them. Many of these species are so local that 

 the exact place of occurrence should be noted if it is to be 

 found again. It will be observed that IsTewman has fused this 

 and the preceding species into one.

An abundant species about Hartlepool, and apparently not 

 occurring elsewhere in either county. It does not occur at all 

 in Yorkshire, and it is difficult to explain its appearance here 

 in such numbers. Until within the last year or two it was 

 plentiful on the railway embankment beside the Wire Eope 

 Works, close to Ironworks, Cement Works, and other places 

 throwing out volumes of smoke and noxious vapours. This 

 place has been destroyed entomologically by the extension of 

 the town, but /Subsericeata is still common all the way along 

 the embankment to Hart Station. It is equally common in 

 the deep cutting from Hart Station to Hezleden Dene, being 

 especially abundant just beyond the first bridge over the 

 railway. It also occurs freely on waste ground — levelled 

 ballast — beyond the Cemetery. We find it commonly on the 

 sand hills beyond Hezleden Dene, and on the grassy banks at 

 Black Hall Eocks and beyond. I have dwelt at length on this 

 because it is very extraordinary that there should be an isolated 

 colony here, where the species may be said to swarm, and no 

 other habitat within at least one hundred miles. Meyrick says
