534 Rev. K. St. Aubyn Rogers' Bionomic Notes on 



fdicia and nvni are indeed distingnislied from the males 

 by the pale markings in the black hind marginal border, 

 but in spite of this are indistinguishable upon the Aving 

 (see p. 52'J). Mr, S. A. Neave, M.A., B.Sc, has called atten- 

 tion to this upper surface aposematic pattern and has 

 pointed out that Acrctea vinidia {tenella) possesses a very 

 similar upper surface (Trans. Ent. Soc. Lond., 1906, 

 p. 210). E. B. P. 



d. PardopsiH 2ninctatissima, Boisd., as a model. 



P. 2nindaiissima is a very common widespread species in 

 East Africa and there is generally associated with it a 

 Lycsenid, Pentila amenaida, Hew., and in other localities 

 other species of the same genus. Both are woodland 

 species, though the Lycsenid prefers much more shady 

 places than P. 2nindatissima. The latter is altogether duller 

 in colouring and its flight is much nearer the ground. 



When at Taveta I was much struck by the resemblance 

 of a diurnal Geometrid moth, Petovia dichroaria, Herr.-Sch., 

 which I took flying with P. amenaida, on December 9, 

 1905. The resemblance does not appear very strong in 

 the cabinet, but on the wing the similarity of their flight 

 and tlieir general aj^pearance is very deceptive, so much 

 so that I have had difficulty in discriminating between the 

 species in the living state. The moth is somewhat brighter 

 in colouring than the Lyca^uid. P. 2mnctaiissi7iia is 

 commoner at Rabai than at Taveta, and P. amenaida 

 is also abundant, but I do not remember seeing the 

 moth. 



P. amenaida gives one the idea of being itself protected. 

 It is very lond of settling in little companies on low plants, 

 and if disturbed often opens its wings a few times without 

 quitting the surface on which it is resting. Its flight is 

 very feeble indeed. 



[Bcchai, August 29, 1908. 



I have lately taken Pentila amenaida and Pardopsis 

 punctatissima together. Many specimens of the Pentila 

 are smaller with the spots fewer and smaller, so as to bear 

 little resemblance to the Aeriea. Although the Pentilas 

 are more addicted to Ibrest country and the Pardu2)sis to 

 grass-lands with patches of bush, they may be seen fly- 

 ing together. The Pentila is even commoner than the 

 PaTdo2)si!i.^
