Hybernia rupicapraria W.V. Bretton!! (B.M.) ; Everlng- 

 ham ! ! (/. Sum?ier) ; Skelmanthorpe, "scarce " (B.Af.) ; 

 Skipwith ! ! {C.D.A.). 



Hybernia leucophaearia W. V. Light and dark forms 

 (the latter including the variety nigricaria Hiib.), in 

 about equal abundance at Doncaster {H.H.C.) ; the 

 variety nigricaria at Everingham {/. Stini7ier) ; Great 

 Ayton (T.A.L.) ; Guisborough {T.A.L.) ; Skelman- 

 thorpe ! {B.M.). 



Hybernia aurantiaria Hilb. A suffused, almost melanic, 

 male specimen was taken at Horsforth in 1890 by 

 Mr. W. Mansbridge ; and I have also an unicolorous, 

 very dark male bred from a Huddersfield larva {G.T.P.). 



Hybernia progemmaria Hiib. The variety fuscata 

 Mosley has extended its range to other divisions of 

 the county, and is recorded from Mapplewell, near 

 Barnsley ! ! {A.W.)] Doncaster, very rare {H.H.C.) ; 

 York {W.H.). 



Hybernia defoliaria L. Several unicolorous and almost 

 black specimens at Saltaire in November 1896, by 

 Messrs. J. Beanland and F. Booth {W.H.). 



Anisopteryx aescularia W.V. Skelmanthorpe ! (^.vl/.). 



Oporabia filigrammaria H.-S. Apparently common on 

 all the moors in the South West Riding, and in some 

 seasons I have found it abundant at Dunford Bridge, 

 and at Harden Moss Moor and adjoining woods, 

 Huddersfield. At Dunford Bridge, in 1891, I took a 

 very pretty buff-coloured variety, which is figured in 

 Barrett's "British Lepidoptera." The species also 

 occurs at Blubberhouses (G.T.P.); and at Sheffield, 

 " larvae abundant on heather at end of May " {L.S.B.).
