326 LEPIDOPTERA. 



apex and cilia broadly pale yellow. Hind wiugs silky 

 white. 



On the wing from the end of Jul}- till September, in one 

 generation only. 



Larva short, obese and very sluggish ; pale yellow, 

 raised dots black ; head chestnut-brown ; dorsal plate black- 

 brown, divided by a yellow line ; anal plate very small, dark 

 brown. 



June and early in July on Ccntaurca scahiosa, living in 

 the buds, eating out the green seeds and immature florets, 

 indeed the whole contents of the large rounded bud, and 

 filling the vacant space with a tough silken case in which 

 the larva resides. These larvtB were sent me, many years 

 ago, by the late Mr. Howard Vaughan. I supplied fresh 

 buds, but these were disregarded, those in which the larvaj 

 reached me proved sufficient, and in them the pupa state 

 was assumed. 



Pl'PA dark chestnut ; thrust out of the larval habitation 

 on emergence of the moth. 



This fine insect is one of the most local species and 

 confined to the south-east corner of England — at least this 

 is certain, that wherever it has been announced in other 

 districts the specimens, so far as ray experience goes, have 

 proved to belong to the previous species. It flies, like its 

 congeners, at sunset and dusk among the plants of Ccntaurca 

 scabiosa, which grow so abundantly and in such luxuriance 

 about Deal, Dover, Folkestone, and elsewhere on the cost of 

 Kent, about Southend, Essex, and doubtless on the coast of 

 Sussex. Abroad Mr, E. Meyrick has noticed it in Switzer- 

 land; but it does not appear to be generally recognised. 



Genus 1. ARGYROLEPIA. 



Antennaj slender ; palpi elongated, porrected, bluntly 

 tufted, depressed; fore wings broad; without costal fold, 

 dorsal margin rounded ; vein 1 of hind wings thickened.
