It will thus be seen that birds exert a far greater influence 

 upon Lepidoptera than is supposed at first thought ; and although 

 these remarks are but brief, yet they may lead to the expression 

 of more general opinions on the point.

Irregular Emergence or Lepidoptera. — Last year I was 

 much surprised by the appearance of a specimen of Acronycta 

 tridens in my breeding-cage towards the end of October, resulting 

 from a larva obtained in the autumn of 1881. As members of the 

 genus Acronycta are irregular in their appearance I did not take 

 much notice of it at the time; but, as another specimen of 

 A. tridens put in an appearance on the 13th of November this 

 year (1883), I am inclined to enquire whether other entomologists, 

 who are in the habit of breeding this species, have found speci- 

 mens emerge so late in the season. My pupse were kept in 

 a room where there is always a fire, so that the emergence 

 is more intelligible than the breeding of four specimens of 

 Platypteryx unguiada, —three by my friend Mr. Harold Archer, 

 of Ely, on the 8th and 10th of November; the other by myself, 

 on the 8th of this month (December) : both resulting from pupse 

 kept in tireless rooms, and the produce of larvse which hatched 

 from eggs obtained in May, and pupated towards the end of 

 July. Of the pupae thus obtained only some ten per cent, 

 emerged in August, and the remainder are lying over till 

 next season.— Gilbert H. Eaynor ; Hereward Hall, Ely,

Sussex Lepidoptera - Rhopalocera. — In the December 

 number of the ' Entomologist's Monthly Magazine,' p. 164, a 

 list is given of the butterflies of Huntingdonshire, by Mr. 

 Herbert E. Norris. It appears that during the years 1882—83 

 forty-two species were taken in that county, and the remark 

 is made that " we must not forget that this county was the home 

 of P. hippothoe and P. machaon, and that P. machaon was 

 abundant in the fens, making a grand total of 48 ? (44) different 

 species. This is a large proportion out of the 62 British species,
