 The Pebble Hook-tip has not been very frequently recorded 

 in either county, but it is generally distributed, and will pro- 

 bably be found in all woods where Birch abounds. It is not in 

 the Twizell list, but Mr. Gr. Bolam records it not uncommonly 

 from Twizell House, I^ewham Bog, and Kyloe; Mr. Finlay 

 found it not uncommonly in the Old Park, Ketherwitton ; Miss 

 Eossie has taken it at Kenton; Mr. Hedworth at Thornley, 

 Chopwell, and near "Winlaton Mill. Mr. Maling also met with 

 it at Chopwell, and Mr. Bhagg in Thornley "Wood. Mr. Sang 

 often took it at Wolsingham, and found larvae in the woods at 

 High Force in August, 1877. I never met with it in the Hartle- 

 pool district, but my brother, Mr. H. T. Eobson, has taken it 

 in Castle Eden Dene. It should be looked for at the end of 

 May or the first week in June, where Birch is plentiful. It does 

 not fly till night, but is easily disturbed by day. When at rest, 

 like so many other species, it very closely resembles a withered 

 leaf.

The only record I have of the occurrence of Hamula is that 

 Mr. Henderson took it at Jesmond. Whether he got more than 

 one I do not know, but it seems probable that he only met with
