Specimens of two species of the troublesome pests belonging to this genus were received ;

This species is from H to 8A mm. in length, and has the ground-colour of the legs 

 dark bro^vn, with the exception of the hiinl tarsi, where a broad band on the first joint and 

 the extreme base of tlie seeoiui joint are pale yellow. N. ,l,iiiiiiiixiiiii, which niav be 

 distinguished from the following species by its larger size and dark legs, also occurs in 

 Uganda, where its native name is Mlnni. A correspondent writing from Entebbe with 

 reference to this species recently stated that : " Its bite is very poisonous and irritable, and 

 causes large swellings which usually end in sores. Localities where this fly is present are 

 very sparsely inhabited."

 large median patch ; the anterior grey transverse band is interrupted by three tine black 

 longitudinal lines, which cmlirace the commencements of two admedian longitudinal stripes ; 

 the grey transverse band in front of the seuteljum is a little apart from the latter, and when 

 seen from a certain direction has an almost silvery white sheen, while on the anterior part of 

 the dorsum of the thorax no silvery white coloration is to be seen. The dorsum of the 

 thorax is, especially on its anterior half, clothed with a coat of golden yellow, felt-like hair.
