9*. Salmacis Ste.— Wood, pi. Z.f. 73 & 12.

 varying very Htlle from P. Artaxerxes.

 Castle Eden Dean, near Durham. 



10. Artaxerxes Fab. — Don. 16. b4:\.— Wood, pi. Z.f. 74 & 13. 



13 to 14 lines. Deep brown with a white spot on the disc of the supe- 

 rior, and sometimes a small one towards the base of the inferior wings, the 

 former with a few scarlet spots forming a line near the posterior margin, 

 the latter having the same with ocellated black spots externally ; cilia 

 white spotted fuscous ; undeiside like P. Agestis, the spots on the disc of 

 all the wings are white without a black pupil, sometimes however there 

 are minute black dots on the centre of each spot ; this insect may there- 

 fore prove to be only a local var. of No. 9.

 barren places at the base of Arthur's Seat, the end of June and in 

 August : it has also been captured at the base of Kirk Hill in Lord
