142 THE ENTOMOLOGIST. 



Acronycta alni at Wimbledon. — Lyonell Fanshawe ; 2, Halkin 

 Street West, Belgrave Square, S.W., April 27, 1884. 



Pupation of Eriogaster lanestris. — The following re- 

 markable case of pupae standing over for several seasons may not 

 be without interest to some of your readers. In the autumn of 

 1880 I had half a dozen pupae of Eriog aster lanestris sent me. 

 One emerged in the spring of 1881, the remainder standing over 

 until 1882. In the spring of that year another emerged. In 1883, 

 no other emergence having taken place, I opened two pupae, when 

 I found that both contained fully-formed and living imagines, 

 which crawled about for some days, but, as might be expected, 

 their wings were not developed. During the present month 

 (March, 1884), thinking the two remaining pupae must certainly 

 be dead, I opened them, and found the first one contained a dead 

 imago ; but on opening the second, to my surprise, a living imago 

 was liberated, which immediately crawled upon a dead leaf, and 

 its wings were soon developed to the normal size. I have never 

 had pupae stand over so long before, although delay for two 

 seasons seems to be a common occurrence. — J. W. Tutt; 45, 

 Beaconsfield Terrace, East Greenwich, S.E., March 15, 1884. 



Hybernia progemmaria, var. fuscata. — In answer to yonv 

 correspondent in the last number of the ' Entomologist,' he may 

 be interested to know that I took this variety at light in March, 

 1883, in Sutton Park. I frequently come across very dark 

 varieties also of H. defoliaria in the autumn in the woods near 

 here. — W. Harcourt Bath; Birmingham, May 16, 1884. 



Petasia nubeculosa, retarded Emergence. — In 1881 I 

 reared some twenty larvae of Petasia nubeculosa from Rannoch 

 eggs ; they were full-fed about the end of June, and duly went to 

 earth. In the following spring I vainly searched the breeding- 

 cage for imagines, and the early months of 1883 having passed 

 with a no more favourable result, I concluded that the larvae had 

 died instead of pupating. To my surprise and pleasure, on 

 looking into the cage on March 22nd of the present year, I dis- 

 covered a moth just emerged from pupa ; this was followed by 

 others on the 23rd, 24th, 29th, and 31st, in all five, which (with 

 the exception of the first, which was very slightly crippled) are 

 fine well-developed specimens. — Robert Adkin ; Lewisham, 

 May, 1884.
