P(EDiscA OPPRESSANA. — The lai'va feeds in the spriiio; within the 

 buds of Fopulus nigra, but its maunev of life previous to this has not, 

 I think, been recorded, nor where and how it passes the winter. 

 Hatching in the autumn, it proceeds after the fashion of a Ilcdija to 

 make a small spinning on the under-side of a leaf. As the larva eats 

 away the surface of the leaf, so does the size of the spinning increase. 

 Trumpet-like in shape, and interwoven with frass, these webs are 

 placed in the angles of the ribs. Frequently several are found under 

 the same leaf, but each in its own corner, one beyond the other up 

 the line of the midrib. The larva leaves before the fall of the leaf, 

 and making a tiny cocoon on the branch, remains there till the 

 approach of spring summons it once more to an active life. The 

 curious tubes, something like the cases of a Coleophora, built out from 

 the infested buds, serve probably as safety-chambers, into which the 

 larvae can retreat when moulting and helpless. For the rapidity with 

 which the woody tissue grows in a warm season is surprising, and 

 without some such i)rovision the larva would be exposed to a dangerous 

 amount of squeezing, or else be forced to withdraw and lie outside, a 

 tempting morsel to any roving bird. As some sort of proof, 1 may 

 add that I have actually seen the larva moulting in the tube, and that, 

 except under these circumstances, the structure has always been 

 empty. 



DiCEOEAMPHA PLUMBANA. — I was once asked by Mr. Barrett if 

 I knew the larva of this species, and had to confess that I did not. 

 That was a long time ago, and since then my valued friend has doubt- 

 less discovered the answer for himself. However, as nothing seems 

 to have been written in our various periodicals upon the natural 

 history of this, one of our commonest and most universally distributed 

 insects, I will venture to relate what I now know about it. 1 tirst 

 obtained the larva- in March and April, 1S87, by digging up plants of
