becoming partly detached. There the larva or pupa may be 

 found freely. Mr. Gardner holds that the larva feeds on 

 sycamore seeds, and goes into these places to spin up. I think 

 this very likely to be so. I have never seen any signs of the 

 larva feeding there, nor of young larvae. What we find appear 

 to be full grown larvse in silken cases, or pupse They are 

 never free to move about. Though it is so common in this 

 stage, I never but once saw the imago in the dene at rest on 

 a tree trunk. Mr. Gardner also, who is in the dene much 

 more frequently than I am, never saw but one perfect 

 insect.

E,ather a common species, occurring in both counties. Mr. 

 Finlay found it scarce in Meldon Park. Mr. Backhouse took it 

 at Sunderland, at Tothills, in Castle Eden Dene, and at 

 Darlington. Mr. Sang also took it around Darlington in 

 different places. Mr. Gardner says it is common in Upper 

 Teesdale, and that the larva feeds on oak bark. Stainton and 

 "Wilkinson say the same, but Meyriok says it feeds on oak, and 

 perhaps on apple.

Stainton says this is not rare in the south of England, and 

 Meyrick gives it as reaching York, but it has occurred in South 

 Durham once at least, for Mr. Sang took it in Dinsdale Wood 

 on July 1st, 1860. I have no other record.
