PORTLAND LEPIDOPTERA. 183 



GELECHIA DIFFINIS, Haw. Common. Larva in Rumex. 



* DISTINCTELLA, Zell. Chesil Beach. ' Sometimes common. 



BRYOTROPHA TERRELLA, Hb. Abundant. 



DESERTELLA, Dougl. Very abundant on Chesil Beach. 



SENECTELLA, ZelL Mr. Dale has taken four specimens 



near Portland Bill, which appear to belong to this 

 species (C. W. D.). Recorded Lep. Dorset, 1891, 

 p. 57. Confirmation is desirable, the specimens not 

 being in first-rate condition.

f UMBROSELLA, Zell. Very common on Chesil 



Beach.

 ,, SEMIDECANDRELLA, Sta. and Tlirelfall. Chesil Beach. Not

* The record of " G. celerella, Dougl. Chesil Beach by N. Richardson " 

 in Lep. Dorset, 1891, p. 57, refers to distinctella. 



t B. portlandicella, Rdsn. Not uncommon on Chesil Beach. I have 

 reason to believe that this form, which I described as distinct (Proc. XL, 

 74, and Ent. Monthly Mag. XXVI., 29), is undoubtedly a variety of 

 umbrosclla. It appears also to be specifically identical with mundellu, 

 to which the late Mr. Stainton regarded it as more closely allied than to 

 umbrosella, thus constituting with them, one variable species. Mr. 

 Meyrick unites it with mundella in his Handbook.
