ARGYNNIS EUPFJROSYXE, Ab. 

 By W. Parkinson Curtis. 



The above figure represents a variety of Arygnnis euphrosyne, 

 which I had the good fortune to capture on the 10th June, 1897, 

 flying in a " ride " in Bere Wood, near Bloxworth, in the county 

 of Dorset. It is a very fresh and quite perfect specimen (though 

 late), the species being in full force here on the 20th of May. 



On the upper surface the ground colour of the wings is 

 not the usual fulvous brown, but a raw sienna colour. On 

 the fore wings the usual markings are all present, but con- 

 siderably emphasised, and most of them confluent. The spots 

 along the outer marginal area of the wings are connected, form- 

 ing reniform marks. The hind wings are almost entirely occupied 

 by the dark brown colour, the outer marginal portions of the cells 

 have a row of spots of the raw sienna colour centred with dark 

 brown, and the usual pearl border is reduced by the encroachment 

 of the dark brown to a series of triangular raw sienna-brown spaces. 



On the under side the chief difference of the fore wings from 

 the type is on the outer margin, where of the two usual rows of 

 black spots the inner row only is present, the other row being 

 converted into a series of conical darkish marks, the apex of each 

 touching the corresponding dark mark of the inner row. On the 

 hind wings the first two cells on the abdominal margin of the 

 wings are entirely occupied by a dark greenish brown. All the 

 usual silvery marks are present, but the space between the 

 median and posterior marginal markings is almost entirely 

 occupied by dark sienna-brown.
