DORSET CEPIDOPTERA IN 1892-3. 61 



that Dorset and Devon had been the counties most affected by tliis 

 species in 1893, as it is stated to have swarmed at Lyuio Kegis, 

 Swanage, Poole, and Sidmouth. 



Colias Hyale, tlie otlier British species of tliis genus, has very 

 similar habits as regards this country, but tlie two species are not 

 by any means always affected by tlie same causes. For instance, in 

 1842 Hyale was common, but there were no Ediisa ; whilst in 1877, 

 when Fjdusa was abundant, Hyale was absent. In some of the 

 S.E. i^ortions of England C. Hyale occurred sparingly in 1892, but 

 the records in 1393 are very meagre. The one Dorset record of 

 Hyale for the two years is for Aug. 28th, 1893, at Swanage (Ent. 

 xxvi., 322), but is not, I consider, admissible, as the would-be 

 captor only saio the butterfly on the wing and might very likely 

 have mistaken its identity, as the pale variety of Edusa {Helice) 

 would be very like it when flying. 



Another species, Vanessa cardui, the " Painted Lady," appeared 

 with C. Edusa in immense numbers in 1892, but has been scarce 

 this year, whilst a near connection, Va7iessa Atalanta, the " Red 

 Admiral," which is, as a rule, more regular in its ways than the 

 Painted Lady, was not commoner than usual in 1892, but appeared 

 in unusually large numbers in the autumn of 1893. I doubt if 

 this species is so much given to migrations as its cosmopolitan 

 relation V. cardui, and have no doubt that the autumn individuals 

 of 1893 were all true Dorset natives. Another butterfly which 

 has been in swarms this season is Polyommatus Phhvas, the " Small 

 Copper." 



In connection with the immigration of butterflies in ] 892, there 

 appears to have been also an immigration of a few kinds of moths 

 Avhich are generally great rarities in tliis country. For this 

 county several are recorded by Mr. Eustace Bankes from Purljt'ck, 

 including Catocala electa, found by him in a ghis^s frame wasji trap 

 in his garden, and Micra parva taken in a salt marsh, also an 

 unusual locality for it. He states (E.M.]\f. xxviii., 309) a 

 specimen of Vanessa Antiopa, the "Camberwell Beauty," was seen 

 on the wing by Mr. Geffckcu whilst driving from Swanage to
