132 THE ENTOMOLOGIST. 



north and north-west. I should particularly like to know if 

 anyone has taken epiphron on any of the following mountains : 

 Pillar, Steeple, The Sail Hills, High Stile, Red Pike (Butter- 

 mere), Dale Head, Hindscarth, Ptobinson, Grassmoor, Skiddaw, 

 Saddleback, or the Armboth Fells, or on any of the fells beyond 

 Helvellyu which end in Great Dod. 



In looking for other insects besides that just referred to, 

 Lingmoor Fell offered the most likely ground for search. This 

 is the fell which divides Little and Great Langdale Valleys, and 

 is almost entirely covered with heather. It is about 1400 ft. 

 high at its highest point, and is the only heather- covered hill 

 anywhere in the neighbourhood. Almost the first insect cap- 

 tured on first ascending to the " heather-region " was Plusia 

 interrogationis. We did not investigate this fell until we had 

 been there a week, and as we had taken enough E. epiphron, 

 we turned our attention for almost the whole of the remaining 

 week to hunting P. interrogationis and other insects over the 

 heather. And truly it was a hunt : a blazing hot sun, heather 

 run wild on stalks as thick as one's arm and growing four or 

 five feet high, hiding rocks over which one stumbled at every 

 other step ; add to these difficulties the picture of two very 

 energetic and very excited collectors running at full speed after 

 little spots which seemed to flash about like lightning, and one 

 has a true picture of those hunts after interrogationis. However, 

 after many tumbles over rocks and into bogs and much scraping 

 of shins, we managed to secure forty-eight specimens of the 

 Plusia during the week. Next year (1903) we went a week 

 earlier on purpose to try and get as many P. interrogationis as 

 possible, but we never saw a single specimen, nor yet have I 

 seen it in the two subsequent seasons in which I went there. 

 In 1903 we met with quite a different lot of insects to those in 

 the previous year, and were particularly engaged in chasing 

 Lasiocampa {Bomhijx) var. callunce, the males of which were 

 dashing about all over the heather ; but they were very difficult 

 to catch, because of the difficulties above enumerated. I turned 

 my attention to finding a female, but could not do so until two 

 days before we left, when, oddly enough, I found two on the 

 same afternoon. Up to this time our total captures of L. callunce 

 were something under a dozen, all males, but we succeeded in 

 taking over fifty more in the two remaining days. It was only 

 necessary to put a female on the front of one's coat and then go 

 and hunt for something else. If a male callunce happened to 

 dash by anywhere near, it would be certain to pull up short, 

 and, after hovering round for a while, would settle on one's coat, 

 and be easily picked off. For the last week in 1902, and the 

 whole fortnight in 1903, we were residing at Blea Tarn House, a 

 farm on the edge of Blea Tarn, at the foot of Pike of Blisco on 

 one side, and Lingmoor Fell on the other. From here we could
