220 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



AcPOnycta aini L. Recorded from numerous additional 

 localities, including larvae found on ash and aspen. 



AcPOnycta ligustri W.V. Everingham ! (/. Sumner) \ 

 Grassing-ton {F.B. and J.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, igoo 

 {G.T.P.). 



Acponycta menyanthidis Esp. Danby and Glaisdale 

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

 Ash has sent me the black form, u'hich 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.

 {C.D.A.). 



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

 brough [T.A.L.).

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

 Huddersfield is a mistake).
