Notocanlhis of a uniformly blackish colour, with numerous white spots 
on the wings. These flies were only observed in one locality in the 
bush about a native village situated on high, dry, sandy soil, near 
Lisala (July, 1904). We possess no particulars concerning its habits. 
Whilst at Boma (Oct. 27, 1904) we also found a number of larvae or 
rat-tailed maggots apparently belonging to the genus Eristalis. 
ORDER ACARINA 
FAMILY HYDRACHNIDAi 
Ectoparasites of Mosquitoes 
ie larvae of four distinct species of Acari belonging to this 
family were observed on several species of mosquito. The site 
prefeired by these ectoparasites was invari 
ably the dorsal area of the abdomen, and 
generally, on the first few segments. Most 
of them, though not all, were fixed to the 
articulations of the segments, to which they 
seem firmly attached. The mosquitoes most
