another trunk. As it sits iu the usual perpendicular posture 

 its head is raised and pointed in a peculiarly alert manner, 

 and it is so restless as quickly to spoil itself if confined in a 

 pill or chip box. Although so greatly attached to fir woods, 

 it will sit on other ti-ees when these are intermixed. It flies 

 at late dusk and is then attracted by flowers, especially those 

 of Knautia arvensis when blossoming in the neighbourhood 

 of the firs. Locally abundant in the South and East of 

 England and to be found in suitable jjlaces throughout 

 the country to Cumberland, though, except that it is scarce 

 in Durham, I find no records for the north-eastern counties,

 Mayo, Tyrone, Armagh, and Donegal. Abroad common in 

 Central Europe, Italy, and Russia.
