 the Isle of Man. but has br^en taken in Scot- 

 land. Dr. Buchanan White says it has been 

 taken once, by Mr. D. P. Morison, near Pit-

 is extensive, but, apparently from the cause 

 above stated, capricious.

Obs. As in the instance of the Marsh 

 Ringlet, at page 97, a preliminary note seems 

 desirable in introducing the butterfly which 

 stands next on my list. To this butterfly the 

 names of Medon, Agestis, Idas, Artaxerxes, 

 and Salmacis, have been successively applied : 

 the first, second, and third of these names 

 appear to be strictly synonymous ; the fourth 

 and fifth were given under the apprehension 

 that the phases or races so named were speci- 

 fically distinct, not only from that which was 

 originally named Medon, but also from each 

 other. At the risk of being considered tedious 

 I will enter a little more into detail. First, 

 the butterfly figured by Esper as Medon, in 

 1777, appears identical with that figured by 

 Lewin as Idas, in 1795 ; and I believe that 

 the figure of Agestis in Hubner represents the 

 same insect. This, which I take as the type, is 

 almost ubiquitous in Gi eat Britain. Secondly, 

 the Hesperia Artaxerxes of Fabricius is identi- 

 cal with the Papilio Artaxerxes of Lewin and 

 Haworth, and is a Scotch insect very different 

 in appearance from Medon. And, thirdly, the 

 Polyommalus Salmacis of Stephens, a butterfly
