Uganda : type and five other specimens from Mpumu, 

 Chagwe, April, 1910 {Captains A. E. Hamtrton, D.S.O., 

 R.A.M.C., and H. R. Bateman, R.A.M.C.). 



Captain Bateman has kindly supplied the following field- 

 note on this strikingly handsome species : — 



" Habitat: — ford across stream bordered by forest at foot 

 of north aspect of Mpumu Hill. 



" Dates when caught : — April 14, 18, and 22, 1910. 



"Average climatic conditions: — heavy rain-storms during 

 night, followed by bright sunshine and showers during day. 

 Temperature 60°-80° F. 



" Habits (so far as observed) : — most active from sunrise 

 (6.0 a.m.) to 9.0 a.m. on bright mornings ; absent during 

 rainy mornings ; active again from 4.0 p.m. to 5.0 p.m. ; not to 

 be seen at mid-day. The Hies are found flying low over the 

 running stream, and alighting from time to time on the 

 stones in the water. They attack man and beast during 

 their active hours, and bite freely. 



" Numbers : — fairly common. 



" Eyes in fresh state iridescent black, or rather iridescent 

 gun-metal colour/' 



The following are the chief points of difference from the 

 South African Rhinomyza denticornis, Wied., presented by 

 ith. perpulcra : — third joint of antennae (both upper and 

 lower branches) longer and more slender ; dorsum of thorax 

 uniformly darker, without any trace of longitudinal stripes, 

 except two admedian light flecks on extreme front margin ; 

 no longitudinal dark stripe, either partial or complete, on 

 lateral edge of dorsum of thorax and lateral edge of abdomen ; 

 black stripes on dorsum of abdomen much broader; wings 

 with apical blotch reaching lower branch of third longi- 

 tudinal vein (instead of extending at most to middle of 

 second submarginal cell), and transverse band connected 

 with blotch at tip of anal cell ; front tarsi entirely and tips 

 of middle and hind tarsi black or clove-brown, instead of 

 only tips of all tarsi being brown or brownish.
