LASIOCAMPA QUERCUS. 93 



lowing that of Z. var. ca//u/me, but this plurality of habit has been 

 noticed elsewhere, and will possibly prove of interest to future workers. 

 Nolcken notes that Teich found, in the Baltic Provinces, in 1865, some 

 full-grown larvae in August that hybernated as pupae, and states 

 that, from four larvae found in the spring of 1866, he obtained 

 three females in June of the same year, the other larva not being 

 fullfed at the end of July ; whilst Bienert, from a larva found at 

 Treiden, and which pupated in July, did not get an imago till the 

 June of the following year — suggesting that here (Baltic Pro- 

 vinces), as with us, the habit is inconstant. The following dates 

 on which larvae have been taken have accumulated: May 17th 

 — 18th, 1899, at Lyntham (Marsden) ; larvae, May 7th, 1871, 

 at Southstoke, common every year at Oxton in April and May, 

 e.g., April 5th, 1895, April 22nd — 29th, 1896 (Studd) ; April 28th, 

 187 1, at Wanstead ; April nth, 1887, June 27th, 1888, July 2nd, 



1890, October 5th, 1897, at Brentwood (Burrows); larvae plentiful

 (Rowland-Brown); June 20th, 1885, at Abbot's Wood (Hanes) ;

 21st, 1896, at Woodhall Spa; June 15th, 1898, at Woodham Ferris 

 (Raynor) ; May 28th, 1887, at Fermain Bay, Guernsey (Walker); 

 halfgrown at Ferrol, in northern Spain, April 4th, 1889 (J. J. 

 Walker); June 27th, 1889, in north Cornwall (Sheldon); April 

 17th, 1890, at Whitwell ; April 16th — 21st, 1896, at Crosby; 

 April 17th — May 4th, 1896, April 17th, 1897, May 5th — nth, 1897,

1 89 1, at Ipswich; April 6th, 1896, at Southend (Williams); June 

 18th — 26th, 1892, at Folkestone (James); April 24th, 1894, at 

 Chilwell (Pearson); April 18th, 1894, at Felixstowe (Morley); eggs 

 laid at end of July, 1894, produced larvae which, on November 

 2nd, were two inches long, pupated December, and emerged April, 1895 

 (Nicholson); larvae, May 28th, 1894, September 26th, 1897, at Newn- 

 ham (Lifton) ; April 30th, 1894, at Salcombe (Turner); half-fed, June 

 10th, 1896, although fullfed larvae had been found May 30th, 1896; 

 others found half-fed in autumn and fullfed in early summer, at 

 Enniskillen, suggest an overlapping of L. querciis and Z. var. 

 callunae, so far as larval habits are concerned (Allen) ; larvae, April 

 15th — 29th, 1897, at Angmering; May nth, 1897, at Leigh (Doll-
