AGRIADES CORIDON. 101 



large and wide valley, covered with eistus, and in the flowery openings 

 on the outskirts of the pinewood beyond ; here they literally swarmed, 

 and one could catch half-a-dozen with a sweep of the net ; this form 

 is different from the type in flight, and appears very near A. theti.s in 

 colour, when on the wing. Chapman further notes that, in July, 1902, 

 he found sparingly, at Avila, on outcrops of limestone, a form very 

 near the arret gonensis taken the preceding year at Cuenca and Albarracin. 

 In 1903, Chapman found the arragonensis form again on the low dry 

 limestone hills between the Santuario de Moncayo and Agreda, the 

 hills covered with sparse aromatic herbage much like that of Cuenca 

 and Albarracin ; the fauna generally is also like that of the latter 

 district, for, besides the similar form of A. coridon just mentioned, P. 

 hylas var. nivescens, Argynnu adippe var. chlorodippe, etc., also occurred 

 there.
