dark cilia. Female similar, except the hind wings, which 

 are smoky brown, with paler cilia. 



Underside of the fore wings leaden brown, with the 

 dorsal blotch and costal dots of the upper side repeated in 

 dull white. Hind wings leaden white. 



On the wing in May and June, and a full second generation 

 in August. 



Larva apparently undescribed. It undoubtedly feeds on 

 Trifoliuiii prcUensc, but in what manner is uncertain. 



The male frequents clover fields especially, but is often to 

 be found among mixed herbage containing clover in fields 

 and rough chalky or sandy ground, and may be seen flying 

 in the afternoon sunshine in numbers when the weather is 

 still, rather conspicuous from the whiteness of its hind wings, 

 and looking like a white dot buzzing about. The female is 

 easily swept in the daytime off the clover, but flies toward 

 sunset. Common throughout the South of England and to 

 Norfolk, Cambs, Oxfordshire and Herefordshire ; also found 

 in Lancashire and Yorkshire; and in Wales in Pembrokeshire 

 and Glamorganshire. It was taken in Scotland — at Mon- 

 crieft'e Hill, Perthshire, by the late Sir Thomas Moncrieffe, 

 but I know of no other record in that country or any in 

 Ireland. Abroad it is common over the greater portion of 

 the Continent of Europe, and also in Asia Minor.
