ADDITION. 



Eeichenbachia o'neili, n. sp. 



Amongst the specimens of B. rivularis which the Eev. J. A. 

 O'Neil sent me from Uitenhage, I noticed one or two specimens 

 lighter in colour and differing in some respects from the type, but 

 I considered them first as a mere variety. However, I drew the 

 attention of the Eev. J. A. O'Neil to this fact, and later on he kindly 

 sent me another lot of Beichenbachia collected together, and contain- 

 ing no less than 225 examples, including B. sulcicomis, Eaffr., 

 B. rivularis, Eaffr., and what I considered at the time to be a variety 

 of rivularis, but which I have now to consider a distinct species. 



It is rather curious to note that out of 225 specimens collected 

 together 75 proved to be sulcicornis, 130 rivularis, and 20 the new 

 species which I name after its captor. 



B. o'neili being of the same size and the same shape as B. rivularis, 

 a comparative description will prove useful :—
