this brown colour is more marked in the ^ of P. rex than 

 in the $. The Danaines again have most proloably formed 

 the model for the spotting of the Fajniios, which is not 

 quite like that of any of its allies. Considering these facts 

 we may cite the above group as a complete example of 

 diaposematic lesemblance. 



Groups with Acr.-eine Models. 



The fine Flanema 23oggei, Dewitz, occurred in fair num- 

 bers in both collections, about 20 specimens from several 

 localities. This very striking species with its brilliant 

 orange band on the fore wing has several interesting 

 mimics. 



Fir^t and perhaps most important of these is the •plane- 

 moides % form of Papilio dardanus, Brown, recently 

 described by Mr. Roland Trimen, F.R.S.,* from a single 

 specimen collected by Mr. Hobley of Kisumu. There are 

 six of these ^ $ in the collections of Messrs. Wiggins and 

 Harrison. Amongst these is a considerable variation in 

 the extent and completeness of the orange band on the fore 

 wing. One specimen is remarkable for showing an inter- 

 mediate character to the $ form of cenea dardanus, and the 

 orange colour, though present, is much broken up into spots, 

 and the basal area of the hind wing is buff coloured as in 

 the cenea. form instead of white as in typical planemoides. 



Other interesting mimics of P. poggei in the collection 

 are : — Pseiidacnea Jiohleyi Neave, (2), in which the resem- 

 blance is best in the $ but remarkably close in both 

 sexes. Pseudacnea huenowi ne^cmanni, Thur. 2. Acriea 

 aurivillii, Stand, (14), syns^posemSiiiG with poggei. Elym- 

 nias phegea, Fabr. (2) (also referred to by Mr. Trimen 

 loc. cit.). 



An outlying member of this group was recognized in 

 the 3 $ ^ of Precis rauanct, Grose-Smith, which bear an 

 orange bar across the fore wing as in the ^$ (14); but 

 have a v:hite discal bar instead of an orange one to the 

 hind wing. This gives them the same general appearance 

 as the above forms. 



Planema tellus, Auriv. (9), from the western districts, is 

 resembled by the recently described Pseiidacrxa terra, 

 mihi (1), also from the western side of the Lake, the 

 resemblance being astonishingly close.
