io6 LEPIDOPTERA. 



Mr. iSyduey Webb has a male with soiiie of the white spots 

 faintly indicated on the fore wings, the rest, and the white 

 stripe of the hind wings, totally obliterated ; and others which, 

 having the hind wings normal, show only a spot or two of 

 white on the fore. Mr. S. Stevens has one of a dark brown 

 and another nearly black, in both of which the central white 

 markings are obliterated. In all these the orange-ringed 

 black spot of the hind wings is unafiected, but a similar 

 variety in Mr. S, J. Capper's collection has even this marking 

 greatly obscured. Mr. Herbert Goss has a handsome specimen, 

 in which the chocolate stripe which lies outside the white 

 band of the hind wings beneath, is visible also in the upper 

 side. Mr. Webb has one from Chichester, in which the 

 usually white spots are of a bu£E colour ; while some of the 

 Northamptonshire specimens show a strange alteration in 

 shape, the fore wings being refuse, and the apex shortened.
