were on the wing, but A. gilvaria and E. ochroleuca were oy 
just appearing. 
Mr. Tarbat having to leave us, Mr. Whittingham and I next 
journeyed to the Norfolk coast. Our first object of ambition was 
Crambus fascelinellus, which I had found fairly plentiful two years 
ago. In the distressingly cold atmosphere not a specimen could 
be induced to fly in the daytime, and not more than two or three 
were found at rest in the sandpits. Our hopes were accord- 
ingly fixed on what could be done at night, and at first they 
seemed doomed to be disappointed. Careful searching, however, 
revealed the fact that C. fascelinellus was about. It was found 
sitting, like C. contaminellus, an inch or two above the ground, but 
only on the spots, at the back of the sandhills, where a few 
scattered blades of grass struggled up through the sand. It 
seldom sat on the marram or on other grasses where these 
latter grew thickly, the surface of the sand had to be well in 
evidence, and in such spots we took a fine series. There was a 
very sbort and partial flight at dusk, which would probably have 
been larger and more general in warmer weather, and the 
insect again flew after ten o’clock. 
The best part of a day, spent in water up to our knees and 
with frequent storms beating down upon our heads, produced 
two dozen larve or pupe of N. canne, and they were well earned. 
Finding that C. fascelinellus was beginning to get wasted we 
next directed our attention to C. alpinellus, which Mr. Whitting- 
ham had turned up two years previously. Our experience was 
most interesting. Still dogged by hostile elements our expecta- 
tions were not great, and when, at our first essay, ten o’clock 
struck without a sign of the Crambid we began to despair. It 
was bitterly cold, but we knew that it must be hiding some- 
where. Then the happy thought struck us of placing our 
lamps on the ground, shining straight into the tangled roots 
of the marram. Almost instantly a little moth began jumping 
out towards the hight, and then another, and our pleasure was 
great when we found that alpinellus had been moved at last. 
Later on the weather improved, and with it the tale of our 
captures of this species. On a fine afternoon there is a very 
general flight between six and seven o’clock, the Crambid being 
then not only on the wing on its own account, but also easily 
induced to fly by tapping the fir trees where it evidently shelters 
as frequently as in the marram. On one such afternoon we 
must have captured fully seventy specimens in an hour anda 
half. The delicate fringes of the hind wings soon get worn, but 
many of the captures were freshly emerged and in splendid order. 
One other insect seems worthy of note. This is the recently 
discovered Retinia purdeyi, which flew round the branches of the 
Austrian pines (at least such we took the trees to be) in the 
late afternoon. Difficult to capture in a wind, it occurred in
