Of this rare little Ne2otis, hitherto only known to me as inhabit- 

 ing the Diu'baa district of Natal, there is a single example, 

 captured at Christmas Pass on 13th February.

There are two examples of this very distinct Euphoeclra, taken 

 on the Pungwe Eiver 15 miles above Sarmento on September 19th. 

 This species appears to be the solitary representative of its genus 

 in Eastern and South-eastern Africa.

Four specimens from Christmas Pass (February 12th to 26th), 

 one from the Mineni Valley (March 29th) and two from near Vun- 

 duzi Eiver (April 5th), are all of the form in which the underside 

 is warm reddish ochreous and spotted with white ; but in t\\o 

 specimens, dated respectively March 29th and April 5th, the white 

 spots are rather duller than in the rest. 



I have for some time been disposed to think that the well- 

 known variation in the underside of this widely-distributed African 

 butterfly is seasonal, and these dated captures of Mr. Selous's tend 

 to confinn this view. All the specimen taken by Mr. Eriksson at 

 Omrora, tropical S.W. Africa, from 1st to 25*th August, 1887, 

 were (as I have recorded, P. Z. S. 1891, p. 80) of the dull underside 

 colouring, wanting the white spots and with the dark markings 

 very faint, and the same is the case with a pair taken in copula 

 near Delagoa Bay, on the 9th August, 1891, by the Eev. H. Junod. 

 A series of dated captures throughout the year is wanting in the
