 presents in many n-spcct a iiiaikrd resemhianee to dengue and 

 Mediterranean " simple continued fever," althouglj according to 

 Lieutenant-Colonel C. IJirt, K..\.>r.C., the actu.il identity of the 

 three diseases is not yet established.* *' I'appataci fever," as the 

 disease conveyed by Phlebototmus jntpaUisii is now known, is caused 

 l)y an ultra-microscopic, "invisible" virus, which circulates in the 

 blood during the first day of the fever, but ap])arently disa|)pears 

 from the circulation by the end of the second day. It is significant 

 that Doerr's investigations, so far as they have yet been carried, tend 

 to show that a certain interval (about eight days) must elapse 

 before a " Pappataci," which has sucked tlie blood of a j)atient 

 suffering from the fever, becomes capable of conveying the infection 

 to a healthy individual. f 



Owing to the small amount of material yet received by the 

 Museum, it is at present impossible to say how many species of 

 Phlebotomus occur in Africa. The existence of species in Uganda 

 and Egypt has already been mentioned ; in the former case the 

 species is perhaps Phlebotomus duboscqi, Neveu-Lemaire (Plate I., 

 fig. 4), which, as stated below, was described from specimens 

 obtained from the region of Timbuctoo, French Sudan, and has 

 also been found in Ashanti and Southern Nigeria. The possil)ility 

 that the Egyptian species is the South lairopean /-*//. jxqxiUisii, 

 Scop., has been alluded to above, but in default of .specimens for 

 comparison the question must for the moment remain undecided.
