grey. Mr. De Grey informs me that he has observed the 

 females on the flowers of Senecio Jacohcea, and suspects the 

 larva to feed thereupon. 



Sp. 4. DUBiTANA, Hiibner (1801). duMtana^ Hiib., Treit., 



Steph., Herr.-Schf., Doub. Cat., Stainton, Wilk., 



Heinem., Stand, and Wock. 



Apparently most common near Bristol, and has occurred 



in other localities. The English examples differ somewhat 



from those of the Continent ; in the latter the white portion 



of the fore-wings is strongly clouded with yellowish, whereas 



ours show scarcely a trace of this colour. According to 



Rossi er the larva feeds in the flowers of Senecio Jacohcea, 



Cirsium lanceoJaUim, Picris hieracioides, Hieracium mU' 



rorum and umbellatum. 



Sp. 5. ALBicAPiTANA, Cookc (Zoologist, 1861, p. 7800) ; 

 Ent. Month. Mag. vol. 3, pi. 1, fig. 1. 

 Not known to Herr Heinemann. Occurs at Howth in 

 Ireland, and on the coast of Cheshire. Allied to duhitana, 

 but certainly distinct therefrom ; the fore-wings are longer 

 and narrower, with the hinder margin more oblique; the 

 head greyish instead of clear white ; the ground colour of 

 the fore-wings greyish-white with numerous dark-grey 

 markings, and with a broad dark-grey central fascia, more 

 or less interrupted, the portion on the inner margin being 

 the most distinct. The figure in the Entomologist's Monthly 

 Magazine is characteristic. This may be posterana of Zeller 

 (Isis, 1847), and if so, Mr. Cooke's name will drop. An 

 insect sent under the name of posterana to Mr. Doubleday, 

 by Herr Lederer, is strikingly similar, yet not altogether a 

 satisfactory proof of identity, and it will be desirable to see 

 and compare more examples. It is possible that Heine- 

 mann's posterana is distinct.
