Algiroides. 361 



Most of the specimens from Madje are preserved in the Congo 

 Museum, Tervueren. 



This species, first discovered at Entebbe, Uganda, has since been 

 found at Madje, in the Ituri district of the Belgian Congo, and in 

 South Cameroon. Its range probably extends across the whole forest 

 region of Africa north of the Equator.
