PTEROPHORIDM—A CIP TIL I S. 407 



very small, and feeiling up from April to June ; on bind- 

 weed (f'oncol ruins sepiiun and C. arvcnsis), eating the tender 

 leaves upon the young shoots. 



Pupa very similar to the larva, equally bristly except that 

 the long hairs are wanting; green with a triple row of shortly 

 elongated chocolate-brown spots down the back. Attached 

 by the anal hooks to a pad of silk under a leaf, not by any 

 means always that of the food-plant ; or under or on any 

 other convenient substance ; lying close to the surface, but 

 able to strike vigorously backward with its thorax if inter- 

 fered with. 



This is the most brilliant and attractive in appearance of 

 all the group to which it belongs, indeed its extreme purity 

 and lightness as it flutters from any patch of weeds, when 

 kicked or trodden out, and moves exactly like a bit of jsure 

 white svvansdown drifting over the grass, or the garden path, 

 is always a source of delight and amusement to tlie keen 

 observer who sees it for the first time. Especially attached 

 to neglected gardens and weedy hedges, where it abounds 

 among the common and mischievous bindweed ; and common 

 throughout the Southern, Eastern, Western, and Midland 

 counties of England to Yorkshire and Durham, becoming 

 very local in Lancashire and apparently absent farther north. 

 In Wales it is found in Glamorganshire and Denbighshire ; 

 and in Ireland in the neighbourhood of Dublin, in Wicklow, 

 Wexford, Waterford, Cork, Kerry, Clare, Galway, and Sligo, 

 but by no means commonly- — often, indeed, only singly. 

 Abroad it has a range over almost all Europe, except the 

 polar region, and including the island of Corsica ; also 

 Armenia, Bithynia and Eastern Siberia.
