Congo Free State and Nyasaland Protectorate: type of S 

 from KuAve, West Lualaba, Katanga District, Congo Free 

 State, March 190G (Dr. A. Yale Massey) ; type of ? from 

 Monkey Bay, Lake Nyasa, Nyasaland Protectorate, 

 21. iv. 1908 [Cajitain Hullam Hardy, R.A.M C). Writing 

 on Aug. 9, 1907, ^^ith reference to the specimen taken by 

 him. Dr. Yale j\Iassey remarked : — "On going over my notes 

 I find that this fly "was taken within half a mile of my house 

 at Ruwe, in open bush and on high ground. My attention 

 ■was attracted by its biting me on the hand, causing pain 

 similar to that produced by the bite of a Tsetse : this was 

 the only specimen seen on that occasion. The fly was 

 caught but a few hundred yards from the cattle kraal, but I 

 have no evidence that it bites cattle. A few days later I saw 

 two specimens, evidently of the same fly, but failed to catch 

 either ; they were very quick in their movements ; I have 

 not met with another specimen since." 



As may possil)ly be remembered, in default of actual 

 observations, the blood-sucking habit of Stygeromyia macu- 

 losa, Austen (the type of the genus, described from a speci- 

 men from Little Aden, Arabia), was inferred "from its 

 evident aflfinities and from the shape of its proboscis " {cf. 

 Austen, Ann. & Mag. Nat. Hist. loc. cit. p. 448). It is 

 therefore gratifying to find that the inference in question 

 receives collateral support from Dr. Yale Massey's personal 

 experience in the case of the present species.
