This species is by no means common in ]]ritian, since none of its liost- 

 genus are of at all frequent occurrence ; and the male was almost un- 

 known in 1885, though Bridgman — overlooking Taschenberg's descrip- 

 tion — wrote of it (Entom. 1879, p, 55) "The only difference I can detect 

 is that the prothorax, except the sides, pleurae and metathorax are black, 

 also a longitudinal streak of the same colour on the middle lobe of the 

 mesothorax"; this male is in the Norwich Museum, but the distinction is 

 not sexual, since the thorax is very variable in the extent of its nigres- 

 cence. There are but few indigenous records: Bridgman took a single 



female at Brundall in Norfolk; Porritt recorded it from Meltham Mills, 

 Huddersfield in the Naturalist, 1902, p. 163 ; and there is a — jxissihly 

 local — female in the Hastings INIuseum. I have several specimens, in- 

 cluding both sexes, taken by Chitty at Forres during September, 1892; 

 and an old male from Beaumont's collection, captured by Wratislaw many 

 years ago, near "Bury St. Edmunds," probably Tuddenham Fen, where 1 

 beat a single female on 27th August, 1906, from a birch bush in a dry 

 situation. These were probably from the birch-feeding Cimhcx J\nii>r:Ua, 

 since I hnd O. glai/copfenis recorded in the Pagets' " Nat. Hist, of Yar- 

 mouth": "From Chrysalis of Cimbex I'ariaiis,'' Leach, whose larvae they 

 say were common on birches in Luund Wood, near Lowestoft, in Sep- 

 tember.

 the Puss Moth is, of course, a slip for /'. cephalotes, as the cocoon shows.
