108 CATALOGUE OF MOTHS. 



most brilliant little species, has only once been met with in ■'' 

 England, except in the county of Durham. Gelechia 

 tetragonella also, which is erroneously included in Porritt's 

 Yorkshire list, has not been found at any northern locality, 

 except at Greatham Salt Marsh, Co. Durham, and its only two 

 other known stations are in Dorset and Norfolk respectively. 



Other peculiarities of our fauna will be mentioned in their 

 places. I have no doubt, when both counties are fully examined 

 by competent collectors, many additional species will be found. 

 As it is, the bulk of those on the following list have been taken 

 by less than half-a-dozen collectors in the two counties. 



EXAPATID^. 

 EXAPATE, Zell. 



1. Exapate gelatella, Linn. 



ExajJate gelatella. Staint. Man., vol. ii., p. 282. 



,, congelatella. Meyr. Hdbk. Brit. Lep., p. 543. 



Generally common, but occurring so late in the year, that it 

 is not often taken on the wing. Meyrick gives its most northern 

 recorded habitat as York {i.e., Yorkshire), but Mr. Finlay found 

 it comparatively common in Coal Law Wood ; Mr. Maling took 

 it at light in November (see Transactions, 1875, p. 282), and 

 Mr. Henderson found it in Jesmond Dene. In Durham we get it 

 in Hezleden Dene when we venture there in November or later ; 

 Mr. Dixon took one at Hartlepool in 1883, probably a wanderer 

 from the dene ; and Mr. Sang met with it around Darlington. 

 The female has very small forewings, and seems incapable of 

 flight. I have no doubt the species will be met with all over 

 both counties. 



DASYSTOMA, Curt. 



2. Dasystoma salicella, Hub. 



Dasystoma salicella. Staint. Man , vol. ii., p. 282. 

 Cheiniophila ,, Meyr. Hdbk. Brit. Lep., p. 615. 



Not a very common species ; Meyrick does not give its east-
