In May 1893 I found the dry-season form of this species very plentiful in the Northern Transvaal, and they there exhibited much greater variation than in either Natal or Mashunaland, more especially the females, which presented a wonderful variety of coloration. Most of these forms have been raised to specific rank by Mr. Butler, but he has based his species chiefly on the relative development of the variable seasonal black markings in the male. W e thus get a graduated series from the lightly-marked T. subfumosus, through T. lycorls, giamlnla, friga, Igceus, ramaquebana, to galathinus, in which the upperside markings approach to those of the wet-season form of the species, represented by T. phlegetonla (Boisd.). All these forms exhibit the tinted and irrorated underside colouring, which in South Africa, at all events, is always characteristic of the dry-season form. I have, however, seen very few specimens of this type from Central Africa, and these appear to have been captured in the dry belt of country referred to by Mr. Scott Elliot in his interesting book on that region. It is therefore possible that in the more humid and forest-clad areas the dry-season form may be represented by T. antlgone (Boisd.), which differs from South-African specimens in having |
