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 H.S. Adel, Leeds {C.S.) ; Bram- 

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

 Rombald's Moor (/. IV. C. and C.S.); Richmond (/ Sang); 

 Ripon (/. Waite); Scarborough (T. [F.). 



Larentia didymata L. Abundant everywhere. 



Very dark forms are common in the south West 



Riding. 

 Larentia xx\\x\X\sXr\ga.v\a. JIazu. Of general occurrence and 



in many districts plentiful. Mr. Butterfield has taken a 



peculiar dark form near Bingley. 



Askhaiai Bog {W.P.) ; Barnsley (/Z/'.) ; Bradford! 



(/ IV.C); Huddersfield!! (a r./'.); Meanwood!(/ W.T.); 



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



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



Larentia caesiata 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.P.) ; Ilkley ( IV.E.C.) ; Pateley Bridge {G.Jackson) ; 

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

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



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 Z. ccesiata was not mistaken for it.
