IN SEARCH OF ZYGHNA EXULANS. 219 
Toiling upwards, quite a lot of interesting plants were 
obtained: Polygonum viviparum and Pinguicula vulgaris, with 
its violet-like bloom; also Trientalis europea, here much 
smaller than at Inverurie; whilst the commonest plant of 
of the district was Alchemilla alpina. More sparingly we found 
the striking little Cornus swecica, with its black and white 
flowers: and on the burn-sides, Thalictrum alpinum, with its 
fern-like leaves, and Hpilobiwn alpinum were in turn gathered for 
herbaria; then Rubus chamemorus began to show itself in the 
cloud region, and Tofieldia palustris occurred sparingly on 
damp places. Now, as we were 2000 feet up, we began anxiously 
to look out for our Zygena. The crowberry (Hmpetrum nigrum), 
Arctostaphylos uva-ursi, and the pretty little shrub, Azalea 
procumbens, were all common. At last, at about 2500 feet, I 
netted my first exulans, booming along in the sunshine; it 
was in perfect condition, and a fine example of the form 
subochracea. This put life into our working, and we scoured the 
hillside up and down with only very moderate success ; an hour’s 
hard work resulted in five to me and four to Mr. Gibb; but as 
the sky foretold a change, we worked away with a will, and by 
six o’clock we had each succeeded in getting a fine series. We 
then returned to our quarters for an eight o’clock dinner, well 
pleased with our first day’s work at Braemar, and far too tired to 
try night work. 
Sunday, a welcome day of rest until tea-time, after which we 
started off for a walk to ‘‘ The Linn of Dee,” seven miles out. 
The evening proved fine, and as we returned we saw quite a 
number of red-deer. Few insects were noted on wing; the only 
one | inspected proved to be Larentia cesiata, the first I ever saw 
alive of this common northern species. 
Monday, July 12th, opened dull and showery; however, 
knowing that Zygena exulans was fully out, we decided to devote 
ten days to this part of our work. So we pushed off up the hill, 
the seat of our previous Saturday’s labours, but found the wind 
on the mountain-tops extremely cold and strong; consequently, 
although we worked fully as hard, the result was comparatively 
very poor. When the too frequent rain-showers were driving over 
us, we were glad to cover ouselves up with our waterproofs for 
shelter and warmth. It was surprising to see how soon 
Zygena exulans utilized every short gleam of sunshine, evidently
