70 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



the costa instead of being white is olive-green, and indeed 

 the upper wings are marbled all over with this olive-green. 

 Mr. N. F. Dobree says that this variety greatly preponder- 

 ates about Beverley {G.T.P.). 



Acronycta rumicis Z. Abundant everywhere. 



The dark variety, salicis Curt, is very common at 

 Huddersfield, and doubtless throughout the south West 

 Riding. It also occurs at Doncaster ( W. IV.) ; Richmond 

 {G.P.H.) ; and Selby (T.F.) ; so is probably as widely dis- 

 tributed as the type. 



Acronycta menyanthidis Esp. Generally common on heaths 

 and moors, and sometimes in woods containing bilberry 

 and ling, on which the larva feeds.

 mon, York ( W.P.).
