ABEEEATIONS OF ARQYNNIS PAPRIA AND TRECLA QUEBCUS. 

 BY KENNETH J. MORTON, F.E.S. 



Not the least remarkable result of my summer excursion to the 

 south was the capture of an extraordinary aberration of Argynnis 

 PapJiia. It is a female, and its peculiarity does not lie in its colours, 

 but in their distribution, which will be best understood as far as the 

 upper- side is concerned, from the accompanying figure. It will be 

 seen there is a decided asymmetry in the markings of the fore-wings ; 

 the light terminal and sub-terminal rows of spots, which are distinct 

 on the left, are reduced to mere traces on the right. In the hind- 

 wings the asymmetry is little marked. 



The under-side of the fore-wings is shining green at the tip, the 

 extreme apex being paler ; otherwise these wings are tawny, with a 

 broad median blackish suffusion. In the hind-wings there is a median 

 green band, the base and a broad terminal band being silvery. 



The insect was taken in July, in au extensive wood in Noz'th- 

 amptonshire. 



The figure (PL I) is reproduced from a photograph made directly 

 from the insect under a very powerful electric light. 



I also take this opportunity of recording the capture of a female 

 Thecla quercus, in which the purple of the upper-side of the fore- 

 wings is replaced by a beautiful metallic blue. This was taken also 

 in July in the New Forest.
