150 THE ENTOMOLOGIST. 



cassiope just above these falls, and on up to the top of the hills 

 above. 



Continuing our walk, the road now enters a large birch wood, 

 and this was a favourite sugaring-ground for collectors who 

 made Kinloch their head- quarters. Most of the Noctuae which 

 have been recorded from Eannoch have been taken here, or 

 further along by the loch-side. Sugar appears to be of little use 

 before the middle of June ; but July is the month best suited to 

 it, and August is better than June. In these woods in the early 

 spring the great prize is Petasia nubeculosa, which is to be found 

 at rest. To make a good catch of this species a man needs a 

 quick eye and great patience, for it is dreary work, frequently 

 walking in deep snow, with a cutting wind. A little later 

 Endromis versicolora is to be seen, though by no means com- 

 monly, at rest during the afternoons on the leafless twigs 

 of the birch trees in the same locality. We now come to the 

 Carie (pronounced Caurie) Burn, passing which the road turns 

 somewhat past a few small houses. If lodgings could be obtained 

 here it would save much walking, but I doubt if such could be 

 arranged. The road now rejoins the lake-side, and continues 

 through heathy banks on to Dall. It was on a post just as we 

 enter the two fields before reaching the Dall Burn that Warring- 

 ton found the unique Nyssia lapponaria ; and in the field near the 

 lake the late Mr. Blackburn found three specimens of Sterrha 

 sacraria, an odd find for Perthshire when we consider that South 

 of Spain and North Africa may be considered its more natural 

 home. Here also Weaver said he once saw a Vanessa antiopa. 

 To our left is Dall House, the highland residence of Mr. Went- 

 worth, to whom all the land belongs from Duncan Campbell's at 

 Allt Druithe to the cottage at the west end of the Black Wood, 

 and it is proper to obtain his leave to collect thereon. 



Passing over the Dall Burn we enter the great Black Wood 

 of Bannoch. This is probably the most important locality in 

 Britain for students of our Lepidoptera and Coleoptera. It 

 perhaps cannot be called virgin forest, but it is nevertheless as 

 nearly approaching it as anything we have remaining in these 

 islands. It is therefore probable that many of the plants and 

 insects which occur there are direct descendants for countless 

 ages, without suffering from the disturbance of cultivation of 

 the land, or even forest fires. It is highly desirable that a
