Ixvi, Ixvii, lxxii] Gran 
that shown on November 15, comprised specimens of Lronia 
cleodora, Hiibn., from East London and Natal, Lelenois severina, 
Cram., from Natal and Rhodesia, Teracolus speciosus, Wallgrn., 
Pinacopteryx pigea, Boisd., and P. charina, Boisd., all from 
Natal. In every instance the contrast between forms captured 
during the dry months of the year and specimens of the same 
species taken in the same localities during the rains was very 
distinct. Two points were mentioned as being especially 
worthy of note. The first was the extremely “ dry ” character 
of the examples of #. cleodorw taken both in August and 
September at East London as compared with those taken in 
August at Durban. The difference was so well marked and 
so constant as to suggest the existence in the region south- 
west of Natal of a distinct local race. The second point was 
the appearance presented by the “dry season” examples of 
B. severina from Rhodesia, in which the dark veining of the 
under-side of the hind-wing tended to become faint or to 
disappear ; this disappearance of the veining being in Natal 
specimens a mark of the “ wet season” phase of the species, 
while the “dry season” forms from Durban were in nearly 
every instance heavily veined beneath. Dr. Dixey further 
remarked that the seasonal relations of the various forms of 
BL. severina had always been somewhat of a puzzle, and the 
difficulty seemed to be increased rather than diminished by a 
consideration of the present specimens. More data were 
needed in regard both to this species and to the nearly-allied 
B. mesentina, before any satisfactory conclusion could be 
reached. With regard to the exhibit as a whole, he was well 
aware that by selecting instances it was often possible to make 
out a better case than the facts really warranted. He had, 
however, done his best, in arranging the present series, to 
choose not extreme, but average representatives of each form 
of the various species exhibited.
