appears to be much rarer than it formerly was. It is given in 

 the Twizell list, ^r. Finlay found it in Meldon Park, and Mr. 

 Henderson at Jesmond. Mr. Maling also found it near I^ew- 

 castle. I have no records for the northern part of Durham, but 

 it is stated in Ornsby's Durham that Mr. J. Bungey met with 

 it at Horden. Mr. Backhouse's papers have "larvae on Thorn 

 in June." Darlington is also a "Manual" locality. I have 

 found the larvae myself on hedges round Stockton, at Greatham, 

 and about Hartlepool. These are all the records I have. The 

 larvae being gregarious and spinning a web as they move about, 

 become conspicuous in the hedges and should be easily seen. 

 The imago emerges in February, a time when Lepidopterists 

 are not generally on the look out for insects on the wing, and 

 it is very rarely seen, all our cabinet specimens being bred. 

 Mr. Barrett says, " even when sitting on a Hawthorn spray, it 

 so accurately mimics a dead leaf twisted round the tree that it 

 is almost impossible of recognition." 



Lanestris has the peculiarity of remaining perfectly developed 

 within the cocoon for an almost unlimited period. My brother, 

 Mr. H. T. Robson, of Stockton-Tees, reared a number, some of 

 which emerged, on almost the same day of February, over six 

 or seven years. It is said to have remained in the cocoon for 

 nine years. If we think what the weather often is in February 

 we will see how important a provision this is for the preserva- 

 tion of the race.
