Mr. AV. S. M. D'Urban was the first to discover tliis very Ijcautiful insect 

 in South Africa, having captured two specimens at King William's Town in 

 May 1 86 1. In January T878, I saw an example in the same locality, flitting 

 about flowers in Colonel Bowker's garden. On the Bashee, in Kaflraria Pro- 

 l^er, Colonel Bowker met with many specimens, including some females. At 

 Breidbach, near King William's Town, Mr. Weale observed that this species 

 was more prevalent in wet weather, while Agathina appeared more when it was 

 dry. I am not aware of the occurrence of the species in Natal. A specimen 

 from the Zambesi was in the collection of the late Mr. Hewitson in 1867, and, as 

 above mentioned, Mr. Selous sent two examples from Mashunaland in 1883. 

 Oberthlir notes it as very rare in Abyssinia, the Marquis Antinori having 

 brought from thence only a single specimen.
