SOUTH-AFEICAN BUTTERFLIES. 
Hewitson (Illusf. Diurn. Lep., Suppl., p. ii) thought /. marmoreus 
(Butl.), from the White Nile, to be a variety of /. Bowkeri ; but I have 
not been able to ascertain if this is the case. 
The strongly and intricately marked under side strikingly distinguishes 
this fine lolaus from its congeners. I. aplinceoides, Trim., resembles it in 
the width of the under- side stria3 ; but these are regular and even, and dis- 
posed quite difierently from the corresponding markings in Bowkeri. 
Colonel Bowker, to whom I have dedicated this very beautiful species, 
first met with it in Kaff'raria in the year 1862, and afterwards took a good 
many examples in that territory. I have also received a specimen taken in 
the Albany District of the Cape Colony ; and in 1867 I found two or three 
about stunted Acacia liorricla near Greytown, Natal. It was not until 1876 
that I discovered the butterfly as far to the south and west as Robertson 
in the Cape Colony ; but I had received the $ Variety or Aberration from 
Namaqualand above described as early as 1873. Colonel Bowker's original 
specimen was taken on a sprig of mistletoe {Loranthus) ; and in October 
1864 he noted that other specimens had the habit (which I subsequently 
observed in Natal and at Bobertson) of settling on the dry stems and twigs 
of acacias and other thorny shrubs. At Bobertson I found the few speci- 
mens I saAV very fond of the yellow flowers of a tall straggling Senecio which 
was growing through a clump of rigid thorny bush. The flight of /. Bowkeri 
is exceedingly short, and, apart from the twigs and thorns about its favourite 
resting-places, it is very easily captured.
