THE YOUNG NATURALIST. 



Agapanthia lineatocollis is found on thistles at Wkittlesea Fens; 

 Monks Wood, Norfolk j and Weston, Oxon. 



Saperda Carcharias feeds in poplars and willows in fenny districts, often 

 in pollards. 



S> scalaris is a very beautiful insect. The larva feeds beneath the bark 

 of alder and occasionally oak. It is very rare and local : it has often occurred 

 in the neighbourhood of Manchester, which seems to be its favourite locality. 

 Hobson used to get it in Mere Clough, afterwards a few specimens were 

 captured by Mr. Joseph Sidebotham, accompanied by Crozier, at rest on the 

 upper surface of the leaves. When the sun shone in the afternoon, they 

 could see the insects through the leaves. Mr. Hewitt often told me, when I 

 was a very young man, what a treat it was to capture this species, and often 

 showed me specimens in his collection. It was then supposed to be extinct, 

 however, some years afterwards, when Mr. Hewitt was gathered with the 

 past, I was going through Drinkwaters Clough along with Mr. Kelsall, when 

 I found a specimen of this insect on George Binks' coat. I acquainted them 

 with my capture, and we immediately commenced operations with beating 

 sticks and inverted umbrellas, we succeeded in finding a few more. A 

 recently emerged female of this insect if pinned on a tree will attract the 

 males. For a few years we procured a number of specimens, after which it 

 seemed to again become extinct, although I found two pupa after its supposed 

 extinction. Since then it has occurred at Middleton, but the wood where it 

 occurred has since been cut down. It has also been captured at Sherwood, 

 and Houghend Clough, and Kannoch. It is again supposed extinct in this 

 locality, but I expect it only wants looking for. 



S. populnea feeds in the aspen. The habits of this insect are very in- 

 teresting. The larvte cause tumour-like swellings on the stems and branches. 

 'They do not eat long burrows but remain in the interior of the node, from 

 which they seem to procure a sufficient supply of food, until they arrive at 

 perfection. It undergoes transformation in the interior of the stems and 

 branches, in the nodes or swellings. 



Polyopsia praeusta is found in old hedges at Llangollen. 



Stenostola ferrea probably feeds in the branches of lime trees in Dun- 

 ham Park, which is at present its only known habitat, where I have fre- 

 quently found it. As a long time elapsed without any specimens of this 

 insect being re- discovered, it was suggested to erase it from the British list, 

 when I had the pleasure of rescuing it by discovering it in Dunham Park. 



Oberea OCUlata is found on willows at the Isle of Ely, and in Scotland,
