The niotli sits during the day quietly upon the undersides 

 of the leaves of its food ])lants, and in the beds of Vcciiiin/i', 

 ■on the mountains, may be readily boxed from them as it 

 sits, being (|uite ivadily noticeable on the leaves and stems. 

 At dusk it Hies in abundance over the beds of this plant, and 

 if an attracting lamj) is placed among it after dark the males 

 will assendjle in such numbers as (juite to cover it. This 

 species is also strongly attracted by the blossoms of the 

 common rush. The female is at all times sluggish and is 

 not .«o commonly taken. Usually a northern, and nearly 

 always a mountain, sjiecies; but in Dorset it has been cap- 

 tured several times singly on large heaths, and the same has 

 occurred in the fens and on heaths in Norfolk. It is also said 

 to have occurred in Cornwall and in Ikickinghamshire. In 

 IK'von it is common on and around Dartmoor, and on F.xmoor 

 near Dulverton ; in Somerset on the Quantocks : on the Cots- 

 wolds in (iloucestershire. and on the Black ^lountain, Here- 

 fordshire. In the J\lidlands it seems to occur on all the high 

 hills anil moors in Ijeicestershiri', ^\'arwickshire, Staffordshire, 

 ^Vorcestershire, and Derbyshire, and is still more abundant 

 on those of ^'o^kshire, Lancashire, Cheshire. Cumberland, 

 Northumberland and Durham. In Wales, Mr. \'ivian has 

 taken it in (ilamorganshire, I found it commonly on the slopes 

 of the I'reselly Hills in J'endjrokeshire, and ^\v. Greening in 

 Flintshire, so I have no doubt that it exists generally in that 

 verv suitable countrv. To be found also in the Isle of .Man.
