332. L. caledoniella, Stain. 



Lithocolletis caledoniella. Staint. Man., vol. ii., p. 421. 



,, corylifoliella. Meyr. Hdbk. Erit. Lep., p. 744 



fpartirri). 



This, as suggested by Stainton, is now known to be but a 



darker form of corylifoliella. The larva feeds in the same way, 



in the upper side of hawthorn and other leaves, and the insect 



appears at the same time. It would seem to be a northern 



form, though corylifoliella occurs in the north also. Mr. 



Finlay found caledoniella generally distributed and common 



in those parts of Northumberland where he collected. It is given 



in the " Manual " as occurring at Darlington. Mr. Sang took it 



at Dinsdale, as well as nearer Darlington. Mr. Gardner records 



it for Hezleden Dene only. I think it occurs on all our hedges. 



338. L. nicellii, Stain. 



Lithocolletis nicellii. Staint. Man., vol. ii., p. 421. 



,, ,, Meyr. Hdbk. Brit. Lep., p. 744 



(partim). 



A common species among hazel, on which the larva feeds. 

 It is entered by Mr. Hodgkinson in his list of "West Northum- 

 berland species. It is given in the " Manual " as being 

 abundant at Darlington. Mr. Gardner finds it commonly in 

 Hezleden Dene. It is one of those abundant species that Mr. 

 Sang never entered in his diary. 



334. L. dunningiella, Stain. 



Lithocolletis dunningiella. Staint. Man., vol. ii., p. 421. 



,, nicellii. Meyr. Hdbk. Brit. Lep., p. 744 



(partim). 



This insect is considered by Meyrick to be the same as the 

 preceding. The book description in Stainton ought to be 

 sufiicient to distinguish them.* The present species is reported 

 from West Northumberland by Mr. Hodgkinson, and from 

 Barnard Castle (West Durham) by Mr. Sang. I have no 

 further record. 



* They are readily distinguishable, nicellii being light and dtmningiella 

 dark in colour, but the latter is, nevertheless, a dai'k northern variety of 

 the former, and should be known as L. nicellii var. dunningiella, Stn. —
