This singularly rare species, originally collected by the 

 Dr. A. Smith expedition in S. Africa, and of which the unique 

 type in the British Museum has till recently been the only 

 example, has now been supplemented by two other specimens 

 collected at Katanga in the South-east Congo Free State by 

 Mr. S. A. Neave, and I also possess a specimen from the 

 Transvaal. It has also just been recorded from Kilimandjaro 

 by Dr. Schouteden.
