nothing but brown nervures and some cloudy indications of 

 spots along the hind margin ; another in the same collection 

 has the middle spots of the upper wings above drawn together 

 into a graded central band ; and Dr. IMason has one in which 

 the spots of the upper side are nearly obsolete, and the silvery 

 spots beneath small and few in number. 



Perhaps the most singular of all is one in Mr. E. Sabine's 

 collection, which has the basal spots of the fore wings 

 confluent, and followed by a broad fulvous band in which 

 is a discal spot, but beyond which all the spots are fused 

 together into a broad dark -brown baud, which throws off 

 rays to the hind margin ; hind wings black-brown, with a 

 central fulvous spot and a row of the same before the 

 hind margin ; on the under side, the outer half of the fore 

 wings is rayed or streaked with blackish, while the hind 

 wings have parallel stripes of silvery down their whole length, 

 instead of the usual spots. 



On the wing in June and the beginning of July, or in 

 western districts sometimes through July. Double-brooded 

 on the Continent, but as a rule only single-brooded in this 

 countiy. In August of the year 1868, shortly after meeting 

 with the single specimen of A. Eiuphrosyiu. already mentioned, 

 I secured one example of a similar emergence of the present 

 species, the first brood having then been quite over for more 

 than a month, yet no additional specimens occurred in that 

 district (Haslemere) either in that or other years ; and 

 Mr. Goss assures me that he has never been able to meet 

 with it in the New Forest, although the June brood is there 

 so plentiful. But the late Mr. W. Buckler told me that at 

 Emsworth, near the coast of Hants, his first acquaintance 

 with the insect was in August, and that he did not untU later 

 discover that it was a June butterfly. The most satisfactory 

 piece of evidence, however, is that of Mr. H. W. Barker, who 

 has obliged me with specimens out of a large number which 

 he took on the Sussex coast. He had been collecting from 

 the middle of August 1881, along the coast near Hastings
