111 July larval of T. yiniperda were very plentiful on Pinus 
sylvestris, at Cawston. 
Larval and pupie of Stilpnotia salicis were so abundant at 
Hiclding, tliat on the 5th of July I climbed up a single Poplar, 
and took from it forty of the larval, and seventy yellow-haired 
pupie. 
On the IGth I saw very many Iris on the wing in Foxley Wood. 
During this month and August I took ninety larvae of Leporina 
on Whitwell Common alone, and at Cawston three larvae of 
A, cdni, and two of C. hicusjpis. Also a few more Leporina in other 
places. Almost all were taken by searching Alder leaves, not by 
beating. I took several Leporina larval from the fresh-broken 
twigs of a bush which I had just thrashed in vain. Although I 
have worked Alder in many parts of Norfolk, and in the New 
Forest, I never found Leporina abundant, except on one small part 
of Whitwell Common. 
As an experimental trap for the Cernrce, I nailed some Oak bark 
round the trunk of a Tacamahac Poplar, hoping that Bifida would 
pupate under it, and be safe there from its natural enemy the Green 
Woodpecker. On the 8th of November I took this bark down, 
and found under it three cocoons of Q. bifida, and two others, 
■ probably A. aceris and A. inegacephala. I might have found 
many more if I had not repeatedly beaten every accessible bough 
with a long pole before nailing up the bark. I took from this 
Poplar, by beating, three or four larvae of Bifida, and many of 
S. popidi and A. megacephala, and probably wasted many more 
on the ground. I think if this bark trap were tried on suitable 
Alders, C. bicuspis might be obtained, and also A. alni, though 
the latter would be very difficult to recognize, as it bores into the bark. 
June 28th and July 2nd at Felthorpe I boat three Testudo and 
twenty-two larvte of Ridens from stunted Oak; and on the 1st of 
October, at the same place, eighteen larva3 of Testndo, eight larva} 
of Hamida, &c., also from stunted Oak. 
Larvae of S. ocellatns and S. populi have been fairly common. 
In September I had one of the latter with thirty-two conspicuous 
reddish-brown spots, besides the usual spot on the horn. 
B. ligustri larva} have been unusually common on low Ash 
twigs in hedges, but I found them also feeding on Lilac and on 
Holly.
