CROCOTHEMIS DIVISA (Karsch, 1898). 



Coll. E. B. Williamson: 3 ^, 1 9, Salisbury, Mashonaland 

 (ii . 1900, iv . 1905, Marshall). 



A widely distributed but evidently not common species, known

 it was found, its existence in Africa between Zungeru in Nigeria, 

 Gondokoro in Uganda, Salisbury, Diego Suarez in Madagascar can be 

 admitted.
