Gelechia viscariella. Staint. Man., vol. ii., p. 338. 

 ,, „ Meyr. Hdbk. Brit. Lep., p. 594. 



A northern species, and rather local. Mr. Hodgkinson ap- 

 pears to be the only collector who has taken it in N'orthumber- 

 land — in the west of that county. Mr. Sang took it at Dar- 

 lington nearly thirty years ago. More recently Mr. Gardner 

 has met with it in Hezleden Dene, and bred the insect from 

 larvoe found feeding in shoots and stems of Lychnis. 



142. G. marmorea, Haw. 



Gelechia marmorea. Staint. Man., vol. ii., p. 339. 

 ,, ,, Meyr. Hdbk. Brit. Lep., p. 596. 



A coast species, abundant on many sandy shores, where the 

 larva lives in a tube below the sand, feeding on Cerastium,. It 

 is given as a local species in Mr. Maling's list in the Transactions 

 for 1875, p. 282. In Durham Mr. Sang took it at Seaton Carew 

 in 1853, at Castle Eden Dene mouth, and at Black Halls in

 and Hezleden Dene.

(partim : nee larva).

At the time of, and for fifty years after, the discovery of 

 G. instabilella, other closely allied species, showing like it 

 great variation but now recognised as distinct, were confused 

 with it under the name i?isiabilella by all our leading 

 authorities, including Mr. Douglas himself as well as Mr. 

 Stainton. In 1894, however, in his monograph entitled 

 '^ Lita instabilella, Dgl. and its nearest British allies," and 

 published in the Ent. Mo. Mag., ser. 2, vol. v., p. 80, etc., Mr. 

 Bankes dispelled the deplorable confusion of ideas that had 

 accumulated round the group to which this and the four 

 following species belong, and his conclusions were adopted in
