216 CATALOGtTE OF MOTHS. 



A rare species, and one that appears to avoid the coast. It 

 has not as yet been recorded from the north side of the Tyne, 

 though it appears to occur generally on the south bank. Mr. 

 Patterson met with it at Chopwell ; Mr. Hedworth obtained 

 " several fine specimens at Thornley, in July." (See also Ent. 

 X., 256). Mr. Sticks says ^' only seen imago once, but ova and 

 larvae fairly numerous at Winlaton, Rowlands Gill, and Lintz 

 Green." Mr. Pickard reported it as '' generally rare at Wolsing- 

 ham, but common in 1870." Mr. Sang took it in "Whessoe 

 Lane, near Darlington and also at Hell Kettles. It certainly 

 ought to occur more frequently than these records imply.

I have received but few records of the occurrence of this 

 species, which probably does not extend very far into ]N"orthura- 

 berland. Mr. Einlay took it at Hartburn, but very sparingly ; 

 Mr. Henderson got one or two at Jesmond. Mr. D. Eosie found 

 it common at Swalwell, the larvae on Birch there ; Mr. Ehagg 

 met with it freely at Thornley ; while Mr. Hedworth said it 

 was common throughout that district. It is in the Manual as 

 occurring regularly at Darlington, possibly Mr. Sang thought it 

 too frequent to enter in his diary. "We find it regularly but not 

 commonly in the Denes about Hartlepool. It thus appears to 

 be confined to South Durham and to the neighbourhood of the 

 Tyne Yalley. The green shade on the wings is exceedingly 

 fleeting, and is rarely seen on a captured specimen, which might 

 readily be passed by a beginner as a worn Acidalia.
