PLATE XXXIV. Figs. '2. and 3. 



Polyommatus Salmacis, Stephens. 



Silky brown above, with a macular posterior 

 band of orange-red on all the wings, somewhat ob- 

 solete in the male, and a white spot on the disk of 

 the primary wings, which, however, is occasionally 

 wanting in both sexes, but especially in the female. 

 The fringe is white, slightly variegated with brown 

 at the base. The colour of the under side is grey- 

 ish-brown, the anterior wings with a discoidal white 

 spot, beyond this a curved band of similar spots, 

 with a minute dusky pupil, succeeded by a band of 

 orange spots, bounded on both sides by- a dusky 

 crescent, surmounted with white, the outer margin 

 defined by a dusky line : the hinder wings have a 

 similar marginal band, several scattered white spots 

 towards the base, a larger one near the centre, and 

 a very iiregular row behind the middle, with a broad 

 white central patch connecting it with the yellow 

 band. Most of these spots have a minute dusky 

 pupil in the male, but greatly more conspicuous in 

 the female.
