and I have fouad it in multitudes in the extreme westeiu 

 corner of South Wales. In the Midland Counties it becomes 

 more local, and in many parts scarce or absent ; but it is 

 common in Dovedale, Derbyshire, and also found at Scar- 

 borough ; at (xrange, Silverdale, and Chatmoss, in Lanca- 

 shire ; and is actually recorded as far north as Dumfries. 

 But south of this it has generally assumed the Salmacvi form, 

 as at Richmond, Yorkshire ; and in Cumberland ; while the 

 ArtcLcerxcs varietj^ is, or was, common on the Pentlands, 

 along the Scottish coast on the east almost to Aberdeen, and 

 on the west as far as the Clyde district. In Roxburghshire, 

 just over the Border, Mr. Adam Elliott found it in glades of 

 a fir wood, settling on the flowers of Centaurea nigra. The 

 earliest specimen seen there was on June 19th, and it was 

 usually a July insect, the single brood lasting out until the 

 end of that month. In Ireland only the typical form — if 

 any — appears to have been observed. Mr. Birchall recorded 

 it from the county Wicklow and near Dublin, and also from 

 the Mourne Mountains, near Rostrevor ; but he subsequently 

 expressed doubt about these records. 



Widely distributed in Europe, Asia, and North Africa, but 

 hitherto the varieties Arhtxcrxcs and Salmaci.s do not appear 

 to have been found outside the British islands.
