VAEIETY OF AEGYNNIS LATHONU (mALe). 



Variety of Argijnnis Lathonia {Male). — The male speci- 

 mens taken last year in the vicinity of Dover are so much 

 smaller than usual, and so much darker in colour, especially 

 about the base of the wings, that I have thought it desirable 

 to figure one of them. It is useless to describe the markings, 

 seeing they are so well represented in Mr. Willis's figure, 

 which, like all in the series, is exactly of the natural size. 

 The specimen was taken by Mr. Stevens on the 18th of 

 August, 1872, in the Castle Field, at Dover, and has been 

 kindly lent me for the purpose of figuring in the ' Entomolo- 

 gist.' For particulars of Mr. Stevens's wonderful success, see 

 page 219 of the present volume. 



The capture of Lathonia and Daplidice in unusual 

 numbers during the past season must not be regarded as 

 supporting any particular hypothesis ; I regard it rather 

 as the necessary consequence of a combination of favourable 

 circumstances. Our entomologists now know the exact time 

 and place to seek these species; and the weather was 

 remarkably propitious for their appearance. — E. Newman.
