TRIFID.'E. 37 



Usually taken at sugar. Formerly found near Sheffield 

 and Huddersfield, but it seems to have forsaken these 

 Yorkshire localities. One specimen has been recorded 

 at Trafford, near IMauchester, by Mr. Joseph Chappell, and 

 Mr. Hodg-kinson put upon record the finding of a larva on 

 wild balsam in Westmoreland. In Cumberland it certainly 

 occurs, though rarely, but its home in these islands is in. 

 Scotland. Even in the south of that country— as in 

 Jioxburghshire — it is rare, but in some years common in. 

 Perthshire, and generally distributed in woods and on hills in 

 Aberdeenshire, Inverness-shire, Ross-shire, Moray. Argyle,. 

 and Sutherland. At Moncrieffe Hill. Perthshire, as stated 

 by Sir Thomas Moncrieffe, it did not make its appearance 

 until 1870. In Ireland it is recorded from Kerry and 

 Galway, but is extremely local. 



Abroad its range is very wide, extending over Northern 

 Europe, the hills of the greater portion of Central Europe,^ 

 Piedmont, the Ural Mountain district. Eastern Siberia, and 

 the mountain regions of Central Asia. Moreover, a form 

 known as j://linoidrs, of the same size, shape, and markings,, 

 but of a more unicolorous grey tint, is found in North 

 America, from Canada to Virginia, and westward through the 

 Central United States, but seems to have no reliable dis- 

 tinctive character. It is, however, found on the wing from 

 May to September, though whether in one or two generations 

 does not appear.
