NOTES ON COLLECTING. 73 
vapae, Hmaturga atomaria gs, Humble-bees, and a small black Lady- 
bird with red spots. 
The weather now continued fine right on into the summer, and as 
it promised well for a ‘“‘ butterfly year’ I decided to work the summer 
broods of butterflies, especially as, owing to the restriction on the use 
of the camera, outdoor insect photography was all but impossible. 
On May 9th I saw a § Huchloé cardamines and some Celastrina 
argiolus flying in the streets of Lewes, Sussex, and during a walk on 
the Downs a Tiger Beetle was carried away on a strong cold N.H. 
wind, and was the only insect seen. 
At Dulwich, on May 138th, P. rapae was flying in abundance and 
ovipositing in the kitchen gardens, and C. argiolus was not uncommon. 
Larvee of 7. pronuba had now changed to pupz, and pupee of Mamestra 
brassicae were far too commonly met with. Two earwigs were more 
than once disturbed, in association, in a cavity in the earth and once 
in a flower head, and later on in the season, at Boxhill, I came across 
another pair, and in each case the pincers differed ; in one individual 
they were small and semi-circular, and in the other they were straight. 
I know nothing of earwigs, but was under the impression that, apart 
from minor variations, the difference in the pincers denoted a different 
species. ‘T’wo ichneumon flies emerged from pups of Hecatera serena 
(larvee taken at Hastbourne, August 17th, 1916), which I have not yet 
been able to get identified. The ichneumon larve spun no cocoon, and 
it is obvious that these flies must prey on another host in the spring, 
and are probably double-brooded.  Ayrotis segetum larve had now 
pupated. 
On May 18th I found in my garden a freshly emerged Taeniocampa 
instabilis at rest on the fence, and a number of Cheimatobia bruimata 
larvee spun up between apple leaves. A g and @ Hemerophila abrup- 
taria were also resting on the fence, and in the evening a number of 
P. rapae were found at rest on apple trees, grass and cabbages, and a 
number of batches of ova were destroyed in the day time on the under- 
side of cabbage leaves. 
At Farningham, Kent, on May 22nd, Anaitis plagiata was seen at 
rest on a fenee, and cn the 28rd a g H. abruptaria was taken at rest 
on a fence at Dulwich. 
On the 31st Xanthorhoé fluctuata and Hupithecia venosata were found 
at rest on fences at Swanley, Kent, and a 2 Apamea basilinea was 
flying in the midday sunshine. A strong wind developed in the aiter- 
noon, and the platform, etc., of St. Mary Cray Station was alive with C. 
brumata larvee, which had been blown down from the birch trees which 
they had stripped nearly bare. 
On June 5th Triaena (Acronicta) psi was taken off tree trunks at 
Dulwich, and Mamestra brassicae started emerging. On the following 
day a 2 Spilosoma lubricipeda was found at rest on the fence, 
while rose sawfly larve and C. brumata larve were discovered busily 
engaged in defoliating the rose trees. At this time C. brumata larve 
were reported as doing an immense amount of damage to the apple 
trees in Kent, and large acreages were to ve seen in both Hast and 
West Kent practically bare of foliage. 
On June 8th Dianthoecia carpophaga started emerging from Hast- 
bourne pupe. Orgyia antigua larvee were found devouring the leaves 
of my plum trees, and caterpillars of one of the small ‘“‘ermine” moths
