THE YOUNG NATURALIST. 



have occurred in the Southern part of the island— Cornwall, Devonshire, 

 Dorsetshire, and the Isle of Wight— and under circumstances that makes it 

 probable they were bred in this country. It is an American species of ex- 

 tensive range, and well known for occasional appearance in immense migra- 

 tory swarms. It seems doubtful whether a butterfly so powerful on the wing 

 as is this species could really cross the Atlantic, but a specimen was brought 

 me this year that had been taken on board a screw-steamer coming from 

 America. The gentlemen who brought it had omitted to mark the latitude 

 and longitude as he generally does, but he thought it was some 600 or 700 

 miles from New Orleans. It is easy to imagine a butterfly tired with so long 

 a flight might rest several days on such a vessel, and thus reach our shores 

 in safety and deposit its eggs. In 1876 the same species was captured in 

 Sussex, and was then also supposed to have been reared where taken. Indeed 

 there had been rumours for a year or two before this, of such an insect being 

 seen occasionally. It is quite possible for the species to become naturalized 

 here if a few impregnated females reached us, and like its near relation D. 

 Cfaysippus, that has also occurred in England, it has strong migratory instincts. 

 The time has not come yet, however, when it can be recognised as a British 

 species. 



3. Coleophora Potentillse, Boyd. 

 In the E.M.M. for April last (p. 254), Mr. George Elisha announced this 

 species. Like so many other novelties it appears to have occurred in more 

 places than one. Mr. Elisha took it at Walthamstow and Snaresbrook inEpp- 

 ing Forest. Mr. Fletcher, of Worthing, was taking it at the same time, and 

 Mr. Boyd had fully worked out its life history. Mr. Elisha does not describe 

 the species, and Mr. Boyd's MS. description appears to be unpublished, so 

 there seems a nice opportunity for some one to steal a march upon the dis- 

 coverers of the species and name it anew, thus helping to confuse our lists. 



4. Lithoeolletis Anderidse, Fletcher. 



This novelty is described by Mr. Fletcher in the E.M.M. for July last 

 (p. 40). It was bred from larvae mining birch leaves in October. 



5. Coleophora Tinctoriella, Coverdale. 



Described in September last by Mr. George Coverdale, from larvae found 

 by Mr. Vine, of Brighton, on Genista tinctoria. Mr. Coverdale's article in 

 the Entomologist (p. 225) carefully discriminates between this and the nearly 

 allied species. 



6. Gelechia Tetragonella, Stainton. 

 Described by Mr. Stainton in the E.M.M. for October (p. 99), from speci- 

 mens taken by Mr. Sang, amongst Artemisia maritima in salt marshes, at the
