BIOLOGY 



Life Cycle 



R. tricuspis has been reared by Theiler (correspondence) 

 for tlie morphological studies reported by her (1947) . The 

 life cycle details will be published subseqiiently. 



Ecology 



In order to determine whether there might be ecological or 

 other distributional factors between R. tricuspis and what has 

 been reported as R. lunulatus , Theiler (correspondence) has 

 checked all locality records against data for vegetation type, 

 rainfaill, extent of dry season, and relative humidity. She 

 finds that both range indiscriminately from (l) dry forests of 

 the Rhodesian highlands through (2) highgrass-low tree savannah 

 or Guinea-southern Congo savannah, and (3) acacia desert grass 

 savannah of the Sudan and northern Kalahari to (4) tallgrass 

 subtropical evergreen and deciduous tree and thorn forest.
