ADSC1TA GERYON. 405 



between Painswick and Cooper's Hill, round to Birdlip, it occurs in 

 grassy spots, whilst the hairy larva? have been captured in numbera 

 at the back of the Royal William Inn, at Cranham (Merrin). In 

 the Derbyshire dales, it loves the slopes of the limestone valleys, 

 flying slowly in the sun, and settling on flowers (Sheldon). At 

 Witherslack it occurs on the grassy slopes of a limestone hillside ; 

 around Chinnor, in the glades of the beech woods ; whilst on the long 

 outcrop of the Carboniferous limestone, running from Llanyrnynach, 

 in Shropshire, through Denbighshire and Flintshire, to the Great 

 Orme's Head, the insect occurs in favourable places. Around Bake- 

 well it abounds in some of the dales. In Durham it is found on the 

 coast, beginning about three miles north of Hartlepool, and extending 

 for a considerable distance. At Castle Eden it occurs on rough grassy 

 cliffs, whilst at Sledmere and Richmond it is found on rough banks 

 near the woods. The limestone habitat extends to the Continent, for 

 Lederer notes it as occurring on the limestone hills between Modling 

 and Baden, on Centaurea and thistles. Near Lennig, in the Rhine 

 Valley, it occurs in a wood clearing, basking on flowers in the sun 

 (Fuchs). Zeller has found it in the meadows of the Ober-Albula ; 

 Frey, at Zerniatt, at 8,000 ft., and we have taken it on blossoms, at 

 considerable elevations above Courmayeur, Cogne, Le Lautaret, and 

 other alpine localities.

 year to year; June, at Richmond, Yorkshire (Hewett), June and July, 

 on the Castle Eden coast, and July, at Sledmere (Maddison),
