Auothor fact poi-haps worth noticing about Eanuoch is, tliat while it soems to 
appropriate to itself most of the Alpine and boreal insects, yet it possesses but 
few (and these the commonest) Alpine plants ; while the neighbouring district of 
Breadalbane, lying immediately to the south, has more Alpine and boreal plants 
than any other place in Britain, and yet but few Alpine and boreal insects. Bread- 
albane, however, has higher mountains and less wood, which may perhaps account 
for the difference. 
The following list only contains species that have come under my own 
observation at Raunoch, and does not include nearly all the Lepidoptera found at 
Rannoch, nor even all the species taken there this year. I have, however, men- 
tioned every species (except among the Micros) that I have seen, as it may be of 
some interest to note how many common insects are conspicuous by their absence. 
Pieris hrassiccB, rapi, and napo} ; Argynnis Aglaia and Selene ; Vanessa ■urticcB, 
hybernated specimens of which were abundant in the beginning of July. Of this 
I think there would be only one brood in the year. Erebia Epvphron (Cassiope), 
near Kinloch Rannoch. I was unfortunate with this species, only discovering it 
when rather passde, although I had been on the ground very shortly before and 
seen nothing of it. It appeared this year at the end of July ! The Messrs. Black- 
burn took it at Grayvel, and also on Ben Lawers in Breadalbane. A friend of 
mine met with it abundantly near Killin. Chortohius Pamphilios. C. Davus, common 
and variable. Most specimens were the usual pale form, commonest in Scotland. 
Some of the dark English type also turned up, July 8th and August. C. Typhon 
ditto, and var. Isis. Thecla ruhi, one specimen in the Black Wood, June 28th. 
Lyccena Alexis, L. Agestis, var. ? Artawerxes, Kinloch, June 27th ; sparingly, and, as 
usual, associated with Helianthemum vulgare. I am inclined to agree with those 
who consider this only a climatic variety, and not a distinct species ; yet the 
difference of the food-plants of the variety and of the type is striking, Helianthemum 
vulgare and Erodium cicutarium belonging to widely different orders. The former 
plant only occurs at Rannoch ; but on Arthur's Seat at Edinburgh, and on KinnouU 
Hill at Perth, where Artaxerxes is common, both plants are common ; but I never 
saw the butterfly show any predilection for Erodium. I hope next sprmg to obtain 
some larvEB, and try the experiments that Professor Zeller suggests. Smerinthus 
populi, larvae on sallow in September. Cossus ligniperda, larv^ of all ages in 
birch trees. I know not of this having been met with in the county before, nor do 
I know where else it occurs in Scotland. Its satellite, the beetle Soronia puncta- 
tissima, occurs in the burrows not uncommonly. Mr. T. Blackburn attacked one 
tree with such Entomological ardour in pursuit of beetles, that I was not greatly 
surprised one day, when passing, to see that it had fallen ! I endeavoured to 
obtain for such ejected Cossi as I could find a habitation in a neighbouring tree. 
Hepialus velleda, June 27th. H. Jmmuli, June 25th. Chelonia plantaginis, July 8th. 
^rcWa/u%mosa, very common in the larva state. Orgyia fascelina, \a,rvse. Demas 
coryli, larvEO on hazel ; two on sallow. About Perth the larvae affect birch and 
beech. Pcecilocarnpa populi, larvaJ on alder ; imago appeared October 14th. 
Bohihyx ruhi, larvee very common. B. callunw, common, June 19th ; larvae in 
autumn, on heather, sallow, and .oak. Endroniis versicolor, larvse in September, 
on alder ; T always thought this preferred birch. I could not find any, however, on
