90 LEPIDOPTERA. 



Sp. 17. Heydeniana, Herr.-Sclif. (1848). Heydeniana^ 

 Herr.-Schf., Heinera.; = impliciiana (Zeller), 

 Herr.-Schf. ; suhroseana, Wilk. 

 I long had this species separated from subroseana in my 

 collection, and my attention having been lately called to it 

 by Mr. Barrett, I sent specimens to Herr Heineraann, who 

 returned them with the above name. It may possibly be 

 subroseana, var. b, of Haworth. It frequents heaths, and 

 feeds (according to Heinemann in litt.) m the flowers of 

 G7iaphalium and Pyrethrum inodorum. The costa of the 

 fore- wings is straighter than in subroseana, the wings nar- 

 rower, the ground colour pale dirty greyish-white without 

 rosy suffusion, the central fascia narrower, the apical fringe 

 shorter, yellowish, and with a distinct dark line at its base; 

 the hind wings are pale and distinctly reticulated with grey, 

 whereas they are uniformly dark in subroseana. In Herrich- 

 Schaffer's work the description alone pertains to Heyde- 

 nianttj and not the fig. 369, erroneously referred thereto. 

 An insect sent as implicifana to Mr. Doubleday, by Herr 

 Lederer, does not show the reticulated markings of the 

 hind-wings, but is otherwise similar. 



Sp. 18. ROSEANA, Haworth (1812). roseana, Haworth et 

 Auct. Brit. ; = dipsaceana, Zeller, Herr.-Schf. 

 A common and well-known species, feeding on the seeds 

 of Dipsacus sylvestris. 



Sp. 19. FLAviciLiANA (Doubleday), Wilkinson (1859). 



Not known to Herr Heinemann. It occurs rarely in 

 chalky places in the south of England, where there is no 

 Dipsacus. A most lovely species when in fine condition, 

 and when fresh is suffused with a delicate carmine tint quite 

 different to that of its near ally roseanay which tint is beauti-
