and the latter gentleman observes in his notes : — " This species is very common in Ondonga, and 

 is not uncommon in Damara Land ; it is also found at Lake Ngami. It is usually seen in pairs, 

 and frequents the banks of periodical streams; I never saw it far away from such localities." 



It is probably migratory to this extent, that it leaves the districts where the dry season has 

 parched the ground, and flowers have passed into seeds, for the neighbourhood of " vleys " or 

 streams, where the moisture throws out the blossoms and brings forth the insects upon which it 

 feeds. 



The specimens here figured and described were collected by Mr. T. E. Buckley at the 

 Towanni river, Bamangwato, on the 23rd of October, 1873.
