46- PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



The variety autumnaria Gn. occurs at Hudders- 

 field {G.T.P.); at Richmond {G.F.H.) ; and doubtless 

 elsewhere. This latter variety is by some considered a 

 distinct species, and my own experience is that it is a con- 

 siderably earlier insect in appearance on the wing. 



Oporabia filigrammaria U.S. Adel, Leeds {C.S.) ; Bram- 

 ham {J.Sm.); Halifax {G.T.F.); Huddersfield {F.I.) ; 

 Rombald's Moor {/. W. C. and C.S.); Richmond {J. Sang); 

 Ripon {/. Waite) ; Scarborough {T. W.). 



Larentia didymata L. Abundant everywhere. 



Very dark forms are common in the south West 

 Riding. 



Larentia multistrigaria ^^za Of general occurrence and 

 in many districts plentiful. Mr. Butterfield has taken a 

 peculiar dark form near Bingley. 



Askham Bog {W.F) ; Barnsley (/^.) ; Bradford! 

 (/ W.C); Huddersfield!! (a T:^.); Meanwood!(/ W.T.); 

 Pontefract {B.H.) ; Richmond {/. Sang) ; Scarborough 

 {T. W.) ; Sheffield {A.D.) ; Wakefield {W.T.). 



Larentia csesiata W.V. Very abundant on all the high 

 moors in the West Riding, and many beautiful dark 

 varieties occur. 



Barden and Burnsall Moors !! {W.D.R.) ; Blubber- 

 houses ! {Lord Wahingham) ; Bradford !! {J. W.C); 

 Halifax ! {G.T.P.) ; Harrogate (/ Sang) ; Huddersfield !! 

 {G.T.F.) ; Ilkley ( W.E. C.) ; Pateley Bridge {G. Jackson) ; 

 Richmond {/. Sang); Scarborough {T.W.); Sheffield 



{A.D.) ; York, one specimen in 1877 ( W.F.). 



Larentia ruficinctata Gn. Mr. J. W. Carter sent me for 

 determination a specimen of this species taken on Mal- 

 ham Moor, August, 1876. It had previously been reported 

 from Huddersfield, but in that instance I am not sure that 

 a variety of L. ccesiata was not mistaken for it.
