 Ongadai, Amasia, Piceno Central Italy. 



The series of P. icarus at the British Museum is very 

 meagre ; there are amongst them only some half-dozen 

 var. icarimis, and of these I am not sure that even one 

 is thersites. 



In the Hope Department of the Oxford University 

 Museum are a number of specimens of A. thersites. 



1 ^ taken by Prof. Poulton at Montserrat (Barcelona), 

 about 4000 feet, on July 15, 1901. 



10 specimens, 9^1$, taken July 21-25, 1898, by 

 Miss Cora B. Sanders and by Prof. Poulton, between Visp 

 and Stalden, Upper Echelberg, opposite Visp on the 

 south slopes of the Rhone Valley, and on the Simplon 

 Road near Brieg, 2155 to 2650 ft., the latter (greater) 

 elevation being on the warmer north slopes. The speci- 

 mens in this series average 32 to 34 mm., one being 

 36 mm., as large as var. centra. 



A series of 9 ^^ 1 $ from N.W. Persia, Seir, 8 miles 

 west of Urumiah, captured August 16 (one August 19), 

 1898, by R. T. Gunther. These specimens are very 

 similar to var. orientalis but are rather more brightly 

 coloured, without being so bright and rich as var. gravesi; 

 they expand 24 mm. to 30 mm. 



The distribution of the species is only to be vaguely 

 outlined by the material I possess. It seems to be com- 

 paratively a southern species — southern, that is, in the 

 same sense that damon, admdus, and cscheri are southern, 

 as distinguished from icarus, argus, etc., that extend 

 further north. The most northern localities I have are 

 Weimar (Schreiner) and Saxony. From France I have 

 specimens only from the south-east, Savoy, Dauphiny and 

 Provence, except one specimen from Fontainebleau. From 

 Italy, Piedmont, Piceno and Siena. Spain affords speci- 

 mens from Tragacete, Albarracin and Barcelona. Syria, 

 Persia, Central Asia probably imply a wide Asiatic 

 distribution. 



In the Rhone Valley it occurs at Trelex (near Nyon on 

 Lac Leman), at Ollon. From here, past Martigny and 

 through the most fully examined portion of the valley, 

 there is no evidence of its existence till we find it in 

 Prof. Poulton's series at Visp, unless perhaps specimens 

 taken by Mr. Tutt and myself, not in the Rhone Valley
