who says, "In all localities in wliich it has been found, the 

 collector appears to be bitterly tantalised by the easy discovery 

 of empty cocoons, while full ones seem almost undiscoverable." 

 (Lep. Brit. Is., vol. iii., p. 86). Mr. Barrett also says he knows 

 of no captures of this species in Scotland. Mr. Bolam's dis- 

 covery brings it very close to the Scottish border. Mr. Meyrick 

 assumes it does not occur north of York.

 The Sallow Kitten appears to have been rarely met with in 

 Northumberland. Mr. Hedworth found "one full-grown larva 

 at Lockhaugh, August, 1870," and Mr. Finlay took a second at 

 Longwitton feeding on Dwarf Sallow in September, 1892, which 

 produced an imago in May, 1893. Dr. Lees says it is "not 

 uncommon on river-side willows in Upper Teesdale, larvae beaten 

 in autumn." Mr. Gardner writes " Hezleden Dene, Grreatham 

 and Upper Teesdale, not uncommon in the larva state." Mr. C. 

 Trechmann, Jun., has found the larva at Castle Eden. It is also 

 given in Stainton's Manual as occurring at Darlington. I took 

 the larva on Willow in Crimdon Cut, near Hartlepool, as far 

 back as 1865, where it still occurs occasionally.
