good many it is complete, and in one or two even broad; in a few 
nothing of it remains but the black discoidal spot, in others only the 
costal half is seen. One is rather a rich cream colour. 
In contrast with this, I have only met Avith broken-barred forms 
both in ordinary corylata, and in var. albocrenata in the Rannoch 
district. The lines, too, in the submarginal region are much blacker 
in Rannoch albocrenata, and the transverse line between the basal area 
and the central band is darker. The Tongue specimens are more 
uniformly pale. 
Near this wood we found larva? of Corernia didymata, from which 
a normal female imago was bred, of Cidaria te.stata and Poecilocampa 
populi (new : Moray and Argyle). 
At night I sugared some birch trees, but the only visitor was 
another ■populi larva, which was enjoying a comfortable supper of rum 
and treacle. From these and others I bred a pale male and a dark 
female imago. With the lantern I found a Corernia propuqnata and 
Cabera pusaria, of which Barrett says “ to Moray if not beyond.” It 
proved to be very common, and I took one slightly damaged specimen 
in which the first and central lines are approximated, as in the var. 
rotund aria (a form only recorded once from Scotland), but more so on 
the right than on the left. 
Next day July 1st, was dull and cold, and we found little except 
one worn Cidaria suffumata (new: Moray and Hebrides), Phytometra 
renea (new : Moray and Argyle), Melanthia ocellata, Hepialus velleda, 
and one Emmelesia blandiata, the last named on the underside of a 
beech branch. Doubtless the insect was common near the river, 
where its foodplant was plentiful, but in my experience it is very 
hard to find in the daytime. In the Rannoch district, though flying 
abundantly at dusk, I have only found one at rest on a rock, and two 
or three on tree-trunks. 
On a strip of damp ground near the river E. albulata (typical) was 
abundant, and Tanagra chaerophyllata occurred, the latter new 
(Aberdeen and Moray). I found it in many other places later. 
Here we found a dozen nearly fullfed larvas of Trichiura crataeyi 
(new : Aberdeen, Argyle, and Inverness). They were feeding exclu¬ 
sively on small mountain ash trees growing amongst birch bushes. 
After dinner I strolled out and saw in a rough field, on the other 
side of the river, four or five black-headed gulls. Standing apart, first 
one and then another kept making a sudden dash, flying quickly 
along the ground, and then settling again. I crossed the river and 
found a sparse growth of bracken where they had been, and I saw a 
good many U. velleda flying swiftly amongst it. Almost every night 
afterwards I saw some of these gulls take up their positions" as the 
flight-time of velleda arrived, and depart as soon as it ended. Out of 
two dozen velleda, varying much in size and colour, there were only 
two of the variety i/allicns. 
Nearer the river I took a series of Hydrilla arcuosa (new: Aberdeen 
and Perth). 
The night was wonderfully light—at this time of year there is no 
real darkness in these latitudes—and on the way home, about eleven 
o’clock, I was leaning over a gate, standing quite still, and watching a 
C. montanata flitting up and down over the grass about three yards 
away. Suddenly a gull flew' up behind, checked itself abruptly, opened 
its mouth, and the moth w r as gone. The bird never saw me and flew
