336 THE ENTOMOLOGIST’S RECORD. 
ancient specimens. Calamia phragmitidis also turned up, but in small 
numbers, with a few Heliophila impura, and, of course, several Triphaena 
pronuba were in evidence, with a sprinkling of 7. subsequa (comes), but, 
the fog coming on thickly, we soon beat a retreat to our lodgings and 
beds. The next day was unsettled but commenced fine, and we soon 
set out for the fen with visions of P. machaon before our eyes. ‘These, 
however, for some time seemed doomed not to be realised, butin the mean- 
time my cousin netted several nice Hamadryas io and Colias rhamni with 
an occasional Aglais wrticae and one Vanessa carduwi. I saw a 
specimen of Hurymus hyale right in the middle of the fen, but was 
unable to get within striking distance. Then I missed the first P. 
machaon which appeared, and soon afterwards came across a nearly 
full-fed larva of the same species. The clouds which had been 
threatening for some time began to close round the sun and the air 
became heavy, as though a thunderstorm was coming on, and just in 
the last few minutes of sunshine I succeeded in netting a splendid 
female P. machaon, quite fresh from the pupa; then down came the 
rain and we had to beat a hasty retreat to the shelter of a neighbouring 
cottage, and then home again. ‘The afternoon, which was wet, was 
devoted partly to setting and partly to inspecting Mr. Bailey’s captures 
during the season, which included one Hydrilla palustris, the only one 
I believe taken this season. After dinner we again sallied forth to try 
our luck with sugar, and light also this time, as the night was more 
promising, and the result amply justified our doing so. Sugar 
produced many more specimens than the previous night though the 
species noticed were much the same, and we soon got the lamp to work 
and were busy netting and bottling off the sheet or lamp. When at last 
we determined to turn in I found I had the following species in my box:— 
Tapinostola hellnannt, common, Calamia phraymitidis, Heliophobus 
popularis, Cidaria testata, Hnnomos alniaria (tiliaria), Amathes umbrosa, 
A. c-nigrum, A. rubi, Acidalia immutata, Strenia clathrata, Pterostoma 
palpina (one), Agrotis nigricans, common, T'riphaena subsequa (comes), 
Lithosia griseola with one of the ab. stramineola, besides which many 
other common species were noticed both at the light and at sugar. 
The next day was fine, but very windy, and although we had at first 
intended to return that morning, we determined to have another try 
for P. machaon, with the result that we were able to secure some very 
fine specimens during the morning, one of which, captured by my 
cousin, measured just upon four inches across the wings. We netted 
and saw a great many battered specimens, but were able to secure a 
few very fresh ones. That evening was spent chiefly in setting our 
previous captures and the next morning saw us again at Soham 
railway station where we parted to join our respective families, my 
cousin to Felixstowe, and myself to Hythe, very well pleased with our 
visit to the fen. It was five years since I had been there, and the 
memories of former visits were not among the least enjoyable of my 
experiences this time. I should add that the enjoyment of our visit 
was very greatly enhanced by the comfortable quarters, excellent food 
and cooking, and untiring attention, provided for and bestowed upon 
us by my old friends Mr., Mrs. and Miss Aspland, at the Post Office. 
I may also mention that many larvee of Acherontia atropos have been 
found in the Wicken neighbourhood this season. I have since heard 
from my cousin that he afterwards twice visited Bawstead Ferry and
