Phibalapteryx WgnaXal/ud. Skipwith Common {CD. A.). 

 Scotosia dubitata L. Grassington (JF.M.) ; Skipwith 

 {C.D.A.). 



Scotosia vetulata IF.V. LarvEe of this species were 

 taken in great plenty, from which moths were freely 

 bred, by several lepidopterists at Askham Bogs, on 

 the occasion of the Yorkshire Naturalists' Union's 

 Excursion there in 1900 {G.T.P.). 



Scotosia rhamnata U'.V. Skipwith {CD. A.) makes 

 a second county locality for this species. 



Scotosia certata Hiib. Everingham, scarce (/. Sianner). 



Cidaria psittacata W.V. Blubberhouses, September 26th, 

 1885 {CS.) ; Doncaster {H.H.C) ; Grassington {A. 

 Gibson-Rohertshaiv) . 



Cidaria corylata Thunb. Skelmanthorpe ! ! {B.M.). 



CidaPJa russata W.V. Mr. John Harrison takes very 

 fine almost glossy black specimens at Dunford Bridge ; 

 but the prevailing Yorkshire form is of a dark slaty- 

 blue colour, which is almost unknown in the southern 

 counties. 



Cidaria immanata Haw. I have to considerably modify 

 my remark in the previous list " that the variation in 

 this species is much paler generally than in russata,'"' 

 as in the South West Riding the reverse is often the 

 case. Many of the Huddersfield and Dunford Bridge 

 specimens are almost quite black, but there is also a 

 good deal of very handsome variation in those districts, 

 some examples being beautifully marbled with white ; 

 others variegated with a lovely dove colour ; whilst in 

 others the pale parts are filled with rich browns. (For 

 figures of some of the forms see Barrett's " Lepidoptera 

 of the British Islands ").
