PHVCITID.'E—AI.ISPA. 35 



margin Hatly curved ; shining smoky-white ; cilia white. 

 Female ven' similar. 



Undersides of all the wings shining smoky white ; body 

 and legs yellowish white. 



M. Ragonot says that it is very variable, generally pale 

 grey ; but sometimes so suffused with fuscous scales — the 

 female especially — that the wings become quite of a uniform 

 blackish-brown colour. 



On the wing from June till August. 



Larva and Pupa unknown. 



One of our rarest species — yet so obscure in its appearance 

 and its habits, that it may yet become well known to us. 

 The first recorded was taken on the coast of the Isle of 

 Wight in the year 1876 b}^ Mr. J. B. Blackburn; more 

 recently Mr. W. Warren has placed on record the capture of 

 another, in the Isle of Wight, about the year 1874-5. This 

 specimen he found resting upon a blossom of Inula dysci- 

 ■terica. If I understand Mr. Warren correctly he has since 

 taken a second specimen in the same locality. Beyond these 

 captures we have no knowledge of the existence of the 

 species in these Islands. Abroad its range is very wide, 

 through Southern Europe, South and West Germany, Hungary 

 and Lower Austria ; also through Western Asia, Northern 

 Africa, Madeira, and many parts of North America. 



Genus 17. ALISPA. 



Antennas simple, the basal joint in the male elongated 

 and thickened, the second joint forming a knob, and bent 

 acutely away, the thickening still continued beyond ; palpi 

 very small and slender, flattened at the sides, ascending ; 

 fore wings very narrow, tufted with raised scales ; hind 

 wings not very ample, the hinder nervures distinct. 



We have only one species.
