Pseudolyesena viridicans, FeJdcr, Eeise der Novara, pi. 28. f. 10, 11.

This species must be subject to very great variety, in colour especially, but also in the 

 breadth and formation of the outer margins, judging by the figiu - e in the ' Voyage of the 

 Novara.' All the examples which I have seen are of a dull green-blue, with the margins of the 

 posterior wing very narrow. The underside of Felder's figure agrees exactly with my specimens.
