2l6 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



Cidaria suffumata W.V. This is another exceedingly 

 interesting- species in our county. The so-called "Dover 

 form," from its having- been first recorded from, the town 

 of that name, was, for many years previously, well 

 known in the Huddersfield district. In it the band is 

 very bright blackish-brown, on a bright pale straw- 

 coloured ground, and it is most extraordinary that it 

 should not even yet be known from any district between 

 Yorkshire and Kent. The beautiful black and white 

 form, which since the publication of the last list has 

 been named var. porrittii by Mr. Robson has again 

 been repeatedly taken by Mr, B. Morley and others al 

 Skelmanthorpe, where the " Dover form " is also 

 common, and from which form I have bred the var. 

 porrittii. Mr. Brady records two specimens of var. 

 porrittii at Wad worth, near Doncaster, in 1900 ; and 

 Mr. Sydney Webb, of Dover, has one labelled " Leeds." 

 Mr. Arthur Whitaker records the var. piceata from 

 Worsborough, near Barnsley. (For figures of York- 

 shire forms see Barrett's " Lepidoptera of the British 

 Islands ").
