Species of the Genus Larinopoda. 267 



to the three forms of genitaha described that would enable 

 us to separate them into three species. There are examples 

 from Gaboon, Ituri Forest, and Toro, but unfortunately 

 most of them are females. One male Toro specimen has 

 claspers like 8, and an example from Buamba Forest, 

 Semliki Valley, is somewhat intermediate between 8 and 

 9, though closer to 8. 



In the genus Neptis we have N. swynnertoyii and N. neavei 

 from Mt. Chirinda and Mt. Mlanje respectively, presenting 

 differences in the claspers without constant differences in 

 the external characters, but here there is comparative 

 isolation by separate elevated positions. 



Judging from a modelled map of Africa there would seem 

 to be no insuperable physical barrier to account for an 

 asyngamic isolation of the Ja River and Port Victoria 

 specimens, and yet the difference between these two is very 

 marked. In the absence of sufficient material from inter- 

 mediate locahties, if indeed the butterfly occurs in such 

 districts, we can do Httle more than record the fact that 

 the name lagyra at present applies to a series of forms 

 so far outwardly indistinguishable, but including at least 

 three probably asyngamic communities. 



.With the exception of the forms of lagyra the species of 

 Larinopoda seem well defined and the armatures distinctive 

 and constant. An incident in the present investigation 

 supports this view. Amongst the material of lagyra I 

 found a single example from Sierra Leone. On making a 

 preparation of the armature I was surprised to find that 

 the structure was the same as in eurema, the species which 

 is distinguished by having a black spot in the h.-w. cell 

 beneath. There appeared to be no trace of this spot till I 

 made a microscopical examination, when I found, where the 

 spot should be, a few grey-black scales. The specimen is, 

 in fact, an example of eurema with the spot almost obsolete.
