RANNOCH. 149 



(same date). On the tops of higher mountains south of this, and 

 all the way west to head of the loch, if above 2000 feet, may be 

 found Erebia cassiope (July 12) and Psodos trepidaria (July 1). 

 I need hardly say sunshine is absolutely necessary for these to 

 take wing, as also for Anarta mdanopa (June 3) in same 

 localities. This species is later than A. cordigera, which prefers 

 a little lower down the hill-sides ; these latter may be found at 

 rest, when there is no sunshine, upon large stones, with an oc- 

 casional Acronycta myricce, and, if well looked for, a couple or 

 three dozen a day may be taken about May 8th to 16th. Still 

 lower on the mountain's side amongst heather we shall find in 

 the early days of May the lovely little Fidonia carbonaria flitting 

 in gleams of sunshine, frequently over the fresh fallen snow of 

 early spring. Under the crowberry a little later are to be found 

 the pupse of Pachnobia hyperborea, once the great prize of the 

 locality. I took my specimen on the 10th of July, but that is 

 perhaps rather late for the imago state of this species. On the 

 lower slope of the hills west of Innerhadden, and just above the 

 loch, Crymodes exulis has been taken at sugar in July, but only 

 odd specimens. This species also frequents certain flowers, 

 orchids among them. It has been taken close by the road-side 

 near the lake between Kinloch and Carie, and amongst the birch 

 trees nearer the latter. 



Keeping along the road at the foot of the hills to the westward 

 we come to the first burn of importance, which runs into the 

 loch from the south. This is Allt Druithe, and it is by the side 

 of this that stands Duncan Campbell's cottage. Although small, 

 it is a most picturesque burn, and full of interest for both 

 entomologist and botanist ; many rare and characteristic plants 

 occur by its sides a little way up to a fine waterfall, just 

 before reaching which is the only locality where I have taken 

 Larentia ruficinctata (August 10). At the same time Cidaria 

 immanata in endless variety, with other Geometers, may be 

 disturbed from the rocks overhanging the burn ; all are worth 

 looking at, as variation seems peculiar to this locality, especially 

 in the case of Ypsipetes elutata. There is a rare fern, which 

 grows right under the fall just spoken of, viz., Hymenophyllwm 

 trilsoni, and Asplenium iriride also occurs there. In passing I 

 may mention that I have found some eighteen species of ferns 

 in Bannoch, and many of them are rare. I have taken E.
