Africa orientalis (ins. Pemba). 



The three African species of this genus, which are ail macro- 

 pterous, seem to differ only in colour, the structural characters and 

 puncture being the same in ail species. As they are strongly myr- 

 mecomimetic, though in a somewhat less degree than the two 

 brachypterous Asiatic species, it is not impossible that the colour is 

 dépendent on that of the ant with which they occur, and that they 

 are forms of one species. The common Indian D. inflatus Kirby has 

 constantly been found associated with the ant Polyr hachis spinigera 

 to which it bears such a striking resemblance. No observations 

 hâve yet been made in Africa as to the modus vivendi of the macro- 

 pterous species of Dulichius.
