234 Miss M. Robertson. Flagellate Infections in [Feb. 24, 



Our remarks on p. 232 appear to be justified, but detailed discussion must 

 be deferred.

While carrying out other work at Mpumu, the opportunity has presented 

 itself of examining the Herniptera from the surrounding country, and some 

 interesting protozoan infections have been found. The group has a certain 

 importance in this connection in that it includes the two parasitic genera, 

 Cimex and Conorrhynus. Cimex has fallen under suspicion in regard to 

 kala azar, and a species of Conorrhynus is definitely incriminated as the 

 transmitting agent of the South American trypanosomiasis. Certain non- 

 parasitic species, generally belonging to the group of the Reduviidse, 

 occasionally attack man. An instance of this has been reported by 

 Dr. H. L. Duke from the neighbourhood of Mpumu. He has on several 

 occasions been bitten by a hitherto unrecorded species of Henicocephalus. 

 Cases of this kind are also known from other parts of Africa, and from 

 India. It is, therefore, not without interest to obtain some knowledge of 

 the Protozoa infesting Herniptera generally, and more especially of the 

 flagellates. 



So far as I am aware none of the species dealt with here are known to 

 attack man or other vertebrates.
