BIOLOGY 



This interesting tick seems to be rare wherever it occurs. 

 Its life cycle is \inknown. It sometimes occurs in large numbers 

 on single animals or herds. For instance, in Matthysse's (1954) 

 study of ticks in Northern Rhodesia, this tick was found only 

 once on cattle, but the collection consisted of eighteen males 

 and fifteen females.
