The Congo Expedition collected in the same region as did Dr. Rodhain numerous larve from the white rhinoceros. The label which accompanied these specimens bore the note ?Faradje, Feb. 3 and 5, 1912, from Rhinoceros; most of the stomach practically studded.' They did not differ from those which I had previously examined from the Uele district and must also be referred to Gyrostigma pavesii Corti (syn: G. rhinocerontis bicornis Brauer).
In commenting upon this discovery of Sj?stedt, Poulton [Proc. Entom. Soc. London, 1908, p. xxix-xxx] refers to a curious observation by S. A. Neave: in 1908 that entomologist observed, in the valley of the Luangwa River (N.E. Rhodesia), three very large f
In 1914 my good friend Dr J. Rodhain, who by his patient researches has contributed very largely to the progress of African parasitology, succeeded in rearing a number of imagoes from gastric larvae collected from Rhinoceros simus cottoni in the Uele district (northeastern Congo).
In 1885, Brauer was able, for the first time, to examine the gastric larvae from a specimen of Rhinoceros sumatrensis, which died in the Zoological Garden at Hamburg. He recognized that they were distinct from Gasterophilus and placed them in a new genus Gyrostigma, under the name of G. sumatrensis. [Verh.k.k.zool.bot.Ges Wien, 34: 269-270, tab.X]
