Notes on Lepidoptera reared during 1906. — From ova deposited 

 by a female Angerona prunaria, taken at Bricket Wood, near Watford, 

 on June 27th, 1905, I have this year reared a number of specimens. 

 The moth laid over three hundred eggs, and the young larvae were 

 sleeved on plum. In the autumn I divided the brood, giving part to 

 my friend Mr. A. E. Gibbs, of St. Albans. The larvae which I retained 

 were kept in bags in a shed during the winter, and in the spring part 

 of them were sleeved out again, and the others placed in breeding- 

 cages, and supplied with plum, birch, and lilac. The first began to 

 spin up on May 20th, but some of those in the sleeves out of doors did 

 not do so until about June 15th. The dates of emergence of the 

 perfect insects were as follow : — June 17th, two males ; 18th, one 

 male, one female; 19th, three males ; 20th, ten males, seven females ; 

 21st, sixteen males, thirteen females; 22nd, four males, seven females; 

 23rd, seven males, five females; 24th, three males, four females; 

 25th, one male, six females ; 26th, one male, one female ; 27th, two 

 males, one female; 28tb, two females. July 2nd, two females; 4th, 

 one female. Of these, twenty-six males and twenty-six females were 

 of the type form, and twenty-one males and twenty-five females of the 

 banded form (var. corylaria). In addition to these, one male was a 

 cripple, and nine more (males) failed to make good their escape from 

 the leaves enclosing the cocoons. This was owing, I think, to the 

 leaves (plum in most cases) becoming so shrivelled and hard that the 

 moth was unable to force a way out. In future I shall remove the 

 pupae from the cocoons, and put them in moss. Mr. Gibbs bred sixty- 

 four moths, nineteen males and eighteen females of the type form, and 

 fourteen males and thirteen females of the var. corylaria. The total 

 number of imagines obtained from the one brood was one hundred and 

 seventy-two. The moths I bred show a certain amount of variation. 

 One male of the type form has the ground colour of rather deeper 

 orange than usual, and the dark strigulation strongly developed. Two 

 males of the var. corylaria form have tbe band on the hind wings of a 

 greyish colour, and some have the orange spot at the apex of the fore 

 wings almost wanting, while in others it is so much enlarged that it 

 joins the median band. The females of the var. corylaria form vary 

 somewhat in the depth of the colour of the dark border, and also in 

 the size of the yellow spot at the apex of the primaries, but the latter 

 does not join the median band in any of tbe specimens. 



In May, Mr. Gibbs gave me some ova of Nyssa lapponaria, laid on 

 April 21st and 22nd by a female from the Rannoch district. They 

 began to hatch on May 20th, and were all out by the 23rd. The eggs 

 are bright green when laid, and turn a beautiful steel-blue colour
