220 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



AcPOnycta aini L. Recorded from numerous additional 

 localities, including larvas found on ash and aspen. 



Acronycta ligustri W.V. Evering-ham ! (/. Sumner) \ 

 Grassington {F.B. and/.B.) ; Kildale {T.A.L.) ; I found 

 larvae commonly on ash at Leyburn on the occasion of 

 the Y.N.U.'s Excursion there on August 4th, 1900 

 (G.T.P.). 



Acronycta menyanthidis Esp. Danby and Glaisdale 

 (T.A.L.); Penistone Moors! (A.W.); the Rev. C. D. 

 Ash has sent me the black form, which is very fine, from 

 Skipwith Common, near Selby, where he says it is 

 common {G.T.P.). The species is common in the hilly 

 moorland districts of the South West Riding, but very 

 singularly only the very pale form seems to occur there. 



Leucania conigera W. V. Everingham ! (/. Sunmer) ; 

 Saltburn {G.T.P.) ; Skelmanthorpe ! (B.M.); Skipwith 

 {C.D.A.). 



Tapinostola elymi 7>. Common at Tod Point, Middles- 

 brough {T.A.L.). 



(NonagPia cannse Oc/is. This species must be deleted 

 from the old list. I feel sure its recorded occurrence at 

 Huddersfield is a mistake). 



Nonagria typhae Esp. Everingham ! ! (/. Sumner) ; 

 Gilling, near Helmsley [L.S.B.) ; Hull (/. W.B.) ; Sher- 

 burn {Lord Walsitigham) ; Stokesley (T.A.L.).

 brough {T.A.L.) ; "one on a gas lamp just outside the 

 town of Sheffield in 1895 " {L.S.B. ). 



Gortyna flavago W.V. Ardsley! ! {A. W.) ; Everingham!!
