any part of Durham except around Hartlepool. Dr. Lees cer- 

 tainly reported it as *' commoner on river-side Sallows in the 

 larva state than the preceding," but this must have been a 

 mistake, as the larva does not eat Sallow. Mr. Gardner also, 

 who has collected carefully in Upper Teesdale, has not met with 

 this species there. He writes, ''on Poplars in gardens about 

 Hartlepool, scarcer now than formerly." Some years ago a 

 number of small Poplars were planted in hedges between West 

 Hartlepool and El wick. A year or two after they were planted 

 I found, on examining them, one or two larvae of this species on 

 every tree. Bifida is generally commoner than Furcula, and I 

 do not think it is really so rare in our counties as the dearth of 

 records implies. Possibly the larva is passed over for that of 

 Vinula.

The Puss Moth is found in most parts of our district and is 

 generally common. It is mentioned in Stephen's Illustrations 

 (vol. ii., p. 9) as occurring at Ifewcastle. It is also in the 

 Twizell list. Ornsby's Durham gives Castle Eden and Durham, 

 and most of the more recent lists contain the species. Mr. 

 Einlay found it ** generally distributed and not uncommon ; " 

 Mr. Henderson met with it at Jesmond, Mr. Hhagg at 'New- 

 castle ; Mr. Hedworth says, "larvae always plentiful on Poplars 

 and Sallows;" Mr. Brady found it very common at Ryhope, 

 Thornley, etc. ; Dr. Lees found it common in ITpper Teesdale ; 

 Mr. Greenwell says ''fairly common about Bishop Auckland," 

 where Mr. Boss only met with a single example. About Hartle- 

 pool it is always common in the larva state, sometimes abundant, 

 and the imago is often seen also.
