VAKIETIES OF PERONEA CRISTANAy y'l^T^ ^91 — 



portance of collecting local races and the varietal forms con- 

 nected with them. 



ViTTANA Group. 



Upper part of wing chestnut-brown, button dark, vitta orange 

 or composed of striate lines. 



[The type vittana, Steph., is well known, and no comment 

 upon it is necessary.] 



Inter mcdiana, Clark. — The specimen Clark made his type 

 has a somewhat paler vitta than the form vittana of Stephens ; 

 there are two similar specimens in his series, and three in 

 Bond's, all of which are identical. The remainder of Clark's 

 series are normal vittana. This varietal name is therefore of 

 but little value. 



Spadiceana, Haw. — A well-known form. From the colora- 

 tion of its wings it is placed in this group, otherwise the vitta 

 being made up of dull and inconspicuous ashy grey lines, its 

 affinity to the striana group in this respect is at once apparent. 



Substriana, Steph. — An altogether darker insect, with the 

 chestnut costal portion much obscured. A well-known form. It 

 has no affinity with the striana group, in spite of the name. 



Profanana and semiustana Group. 

 More or less mottled wings, black or very dark brown tuft. 



A. No vitta. 

 [Profanana, Fab. — Well known, as is also semiustana, Curt.] 



B. Vitta orange to 'palest yellow or white. 

 [Provittana, Desv.J 



Flavostriana, n. ab. — In Bond's cabinet are three, in Clark's 

 one, and I have seen others ; of lightly mottled specimens 

 easily distinguished from the last. The vitta is distinct and 

 white, tinged along the middle with tbe faintest yellow. Head 

 and thorax pale cream. I propose for this variety the above 

 name, which was written on the ticket placed by Bond below 

 his specimens. 



A form wanting a name is similar to bentleyana, Curt., but 

 the head and thorax are white, palpi cream. The large central 

 tuft and vitta pure white. Several specimens have been taken 

 in the New Forest. A very handsome insect. 



Another form, somewhat like the last, but the paler blotches 

 upon the wings almost obliterated by the dark ground colour. 

 Head, palpi, and thorax cream, large button, some subsidiary 

 small tufts of raised scales towards the ends of the wings, and 

 vitta cream. Epping Forest and Folkestone. Can this be 

 Duponchel's combustana ? It may well be, although the mottled
