name, and I propose to call them after their captor. The good 

 work Mr. Purdey has done for entomology in clearing up points 

 of difficulty and original research in the life-histories of many of 

 our Lepidoptera deserve this slight recognition of his services, 

 and the variety will henceforth be known as purdeyana.

Our readers will learn with interest that Mr. Selwyn Image, 

 M. A., Fellow and Member of the Council of the Entomological Society 

 of London, has been elected to the Slade Professorship of Fine Art 

 in the University of Oxford, where, as an enthusiastic disciple of 

 John Euskin, he graduated in 1872 ; Ruskin being the first occupant 

 of this particular Chair. Latterly, as Master of the Art Workers 

 Guild, he has done much to develop a taste for art among the more 

 highly educated members of the community, while his love for 

 entomology finds continual expression in the work of designing, 

 upon which his energies are largely concentrated. A poet and an 

 artist, he has among other charming subjects embodied Hyhernia 

 leucophaaria as the ideal "Spring Usher"; and, at the moment, is 

 putting the finishing touches to the beautiful new seal of the Ento- 

 mological Society — a labour of love, which, we are sure, will be as 

 much admired as it will be appreciated by all his colleagues and 

 friends who are also of " the brotherhood of the net." 



Retarded Emergence of Acronycta megacephala. — On Sep- 

 tember 4th, 1907, a single larva of this species gnawed out a hole in 

 a piece of virgin cork, and therein formed its cocoon. As no moth 

 had emerged by October, 1908, I partially opened the cocoon, and 

 found the chrysalis alive and healthy. Throughout 1909 I frequently 

 looked in the box, but only to find a healthy pupa. On May 27th 

 last the moth emerged — a fine female, it having lain over three 

 winters, and been in a cocoon for a period of two years and eight 

 and three-quarter months. The box containing same w^as kept in a 

 cold room, and in the same position, throughout this period. As 

 Barrett in ' Lepidoptera of the British Islands' says "this species 

 sometimes remains in cocoon through a second winter," I have 

 thought the above worth recording. — W. A. Rollason ; " Lamorna,"

Aberration of E. advenaria. — Among some insects taken for 

 me by my brother near Godalming, Surrey, which I received June 

 5th last, is an almost unicolorous male of this species ; it is very 

 much the colour of worn H. muricata, and has white fringes. It is 

 of smaller size than usual, and must be very similar to the specimen 

 mentioned by Mr. Oldaker (Entom. xli. p. 157) as having been bred 

 by him in 1907 from ova obtained near Haslemere. The insect seems 

 to swarm in that part of the country, where there is a good under- 

 growth of bilberry, and I took a series of it there lately. But for
