220 THE ENTOMOLOGIST. 



in the west of Durham and Northumberland like Satley, Derwent 

 Valley, and Corbridge. In Scotland I have captured it at 

 Achterneed, in Eoss-sbire, and in Ireland I have seen it on rare 

 occasions dasbing along the shores of Lough Fea, Co. Derry. 



Sati/ms stmele, L. Like all grass-feedmg butterflies, this is 

 decadent in these two counties. I saw it last in Durbam near 

 Horden twelve years ago, although I took a single specimen 

 at Budle Bay, in the sister county, in 1915. No such disap- 

 pearance is threatened on the Moray Firtb, for it still remains 

 excessively plentiful all along the sandhills from Burgheadto the 

 Culbin Sands, and the same holds good of the sandhills in 

 Lancashire near St. Anne's. On Fair Head, Co. Antrim, it 

 abounds on the heather just bebind the higbest point. In Fife 

 near Kirkcaldy it seelns to be excessively rare. 



Pararge megie/a, L., and P. ageria, L. In the north-west of 

 England, wherever P. niegcera occurs, it abounds, whereas its 

 congener P. cegeria has vanished; hereabouts both are gone, but 

 in Ireland, in counties Tyrone, Derry, and Antrim, P. ageria is 

 very common. Only in Antrim, at Glenarrift', have I taken 

 P. megcera, and then very sparingly. 



Dianthoecia nana, Eott. {co)ispersa, Esp.). Quite typical forms 

 are to be picked freely enough off the rocks on the beach at 

 Kinghorn, Fifeshire. 



Agrotis agatluna, Dup. Larvae singly on all of the northern 

 Cleveland moors ; imagines at Erica flowers at Findborn, Elgin. 

 Asphalia Jlaricornis. L. Formerly I considered this moth 

 somewhat a rarity in the north-eastern area. Now^ I find it 

 plentifully everywhere with its food-plant birch. Not far from 

 Birtley, Durham, in a small enclosed wood, I find a beautiful 

 melanic form of a curious green-black colour. Also plentiful at 

 Stratbpeffer, Pioss-shire, Forres, and Kippen, Stirling. 



Demas coryli, L. Very common on birch at Forres ; rare on 

 Salix cinerea in Newham Bog, Northumberland. 



Notodonta ziczac, L. Apparently well distributed in the 

 north. On Salix cinerea, S. aurita. S. caprea at Ninebanks, 

 Northumberland ; on S. viminalis, S. alba. S. repens, S. triandra, 

 St. Anne's, Lancashire ; on S. cinerea at Cookstown, Tyrone : 

 on S. aurita, S. Derry ; on S. triandra, Ballycastle, Co. Antrim; 

 on all tbe Salices of tbe caprea group in Elgin. 



N. dromedarins, L. Even commoner and more widely spread 

 than the last species, not only in precisely the same localities, 

 but in addition found at Kippen, Stirling, and in many stations in 

 N. Durham. It also swarms as larvae on bircb on Eston Moor, 

 Cleveland. I have seen tbe larva feeding quite freely on Salix 

 cinerea, althougb birch and alder are the favoured trees in 

 general. 



N. dictceoides, Esp. Occurs fairly numerously on birch at 

 Eston and Inglebv Greenbow, Cleveland ; less commonly in
