156 LEPIDOPTERA. 



earthen chamber, faintly lined with silk, beneath the surface 

 of the ground, often to the depth of several inches. Appa- 

 rently in this condition through the winter in this country ; 

 but in North America it is believed to hybernate in both 

 pupa and imago- state. 



The moth flies swiftly and eagerly in the daytime in hot 

 sunshine and may then be seen, occasionally, hovering at the 

 blossoms of clover, and hardly to be distinguished from the 

 Phosia gamma buzzing around it, except that its colour is 

 much lighter and browner. In dull or cool weather it hides 

 among herbage, sitting with its head downward. At dusk it 

 frequents ivy-bloom, or the flowers of Aster tripolium, Cen- 

 tranthus ruber and Arbutus unedo ; I have taken it at sugar 

 and it seems to be rather strongly attracted by a powerful 

 light. Bare in these islands, indeed, possibly only occurring 

 as an immigrant, since the larva appears never to be met with 

 here, those described by Mr. Tugwell having been obtained 

 from eggs laid by a captured female. The first British 

 specimen seems to have been recorded from Salford, Lanca- 

 shire, in 184-0 by the late Mr. R S. Edleston, and the second 

 by the Rev. Murray A. Mathew, who found it in the year 

 1858 in Devon, flying in a field. More recently it has become 

 rather frequent in that county, being taken almost every 

 year on the coast near Torquay ; and it has occurred in Corn- 

 wall, Dorset, Hants, Sussex, Kent — even so near to London 

 as West Wickham ; Surrey, Middlesex ; once near Reading, 

 Berks ; Somerset, Gloucestershire, Herefordshire, Cambridge- 

 shire, Suffolk. Norfolk, where, at Cromer lighthouse, no less 

 than twenty specimens were obtained in 1875-6 by Mr. W. 

 H. Thornthwaite ; Cheshire, Lancashire, Yorkshire and 

 Durham. In Wales I took a single specimen in a clover 

 field near Pembroke, in one of those years in which Colias 

 Eihisct was common. 



In Scotland it is recorded by the late Dr. Buchanan White 

 in the Solvva}- district; and in the past year (1898) the
