NOTES ON COLLECTING, ETC.

■ Miana arcuosa^ Viminia albovenosa (2nd brood), Lasiocampa quercifolia 
and Odonestis potatoria were coming up strongly, and above all Nascia 
cilialis. I heard of other species, such as Arctia fuliginosa (2nd brood), 
Chilo phrag77iitellus and Her77imia cribralis^ some of which the regular 
“ fen ” workers appear to consider too common for notice. However, 
when midnight arrived we were getting fixed up for boxes, and visions 
of colossal labour in the form of “ setting ” appeared, so, when we 
had used up all the pins in our zinc box, niutually agreed to box 
nothing further except cilialis. Another hour having passed and the 
fun getting a little slower, we closed for the night. The next evening 
was nothing like so satisfactory as the first. Sugar was as productive 
up to about 10.30 p.m., and light for the first hour. Things then got 
very slow, and midnight saw us on the road home. Altogether a very 
large number of specimens rewarded our efforts. Monday found me 
671 route to London, but on Saturday I was at Wicken again for a three 
weeks’ stay. During the whole of the three weeks the weather was bad 
— wet continuously, and sometimes cold, and this led to the almost utter 
failure of light. But there were one or two evenings on which light 
did pay, and on Saturday, August ist, Macrogaster arundmis^ Melia7ia 
fla77i77iea^ Nascia cilialis and the second brood of Vwihiia albov67iosa all 
occurred, rather a mixture for such a date. On another night above a 
score of specimens of Se7‘icoris fuliga7ia were captured and on other 
nights by spending the early hours of the morning at the lamp a few 
No7iagria hell77ia7i7ii were taken. But the weather was dead against 
me in this way of collecting, and only a night now and then showed 
what the resources of the Fen really were in this direction. Night 
after night, however, I went home with above a gross of good Nocture 
off the sugar, including such as Agrotis obscura {ravida) and its vars., 
NoTtagria hdl77ia7i7ii,^ type and var. safurata, Helotropha leucostig77ia, and 
its vars. albistig77ia and limma, Noctua U77ibrosa, Caradrina (all the 
British species except a77ibigua), Triphc67ia interjecta,, T ja7ithma,, Cos77iia 
affiTtis^ with a good specimen or two of C. pyralma^ and Cala77iia 
phrag77iiiidis mostly in considerable numbers. Lithosia griseola and its 
var. stra77ii7teola came to sugar and light freely, Z. lurideola only to 
sugar, whilst odd specimens of HypeTiodes coslcestrigalis, Ma77iestra 
abjecta and T7-ipJice7ia fi77ibria were not unwelcome visitors. The 
second brood of Noctua rubi appeared about August 14th, and a few days 
before N. baia was still in good condition. Agrotis tritici var. aquilina 
occurred, but was not common like its congener A. nigrica7is, of which I 
got some good forms. I was surprised at the few specimens of Orthosia 
7ipsilo7i considering the vast quantity of poplar and willow in the neigh- 
bourhood, and was also much astonished at the late appearance of 
Cala77iia phr ag77iitidis at Wicken, its first appearance being quite a 
month later than at Greenwich, and, although I did not want the 
species, was rather pleased to pick out a few beautiful var. rufesceTts from 
the paler var. and typical form. Tortrix du77ieta7ia was late, only a few 
specimens occurring until quite the last few days of my stay. Fine Hyria 
auroraria were picked up until August 15th. On the same date 
Hydrelia 7mca occurred, and Mr. Porritt saw a specimen of the second 
brood of Papilio 77iachao7i on the wing. Since then I have bred others. 
With regard to the double-broodedness of this species it occurs to me 
that the individual members of a family are double-brooded in alternate
