central bands, the colouring, and particularly the basal 

 markings of the underside of hind-wing, being singu- 

 larly similar ; but the Panopea has a short sub-apical 

 white bar not found in the Acrcea, The latter marking 

 is, however, not noticeable in flight ; and I fully believed 

 the first example that I met with to be Acrcea Arjanice, 

 (which was common in the same wood), until it settled 

 on the damp pathway immediately before me, I searched 

 in vain for a second specimen on that day, as well as on 

 many subsequent occasions in the woods near Port Natal; 

 but, on the 24th February, 1867, on the edge of a forest 

 near the village of Verulam, about twenty miles north- 

 ward of D'Urban, I met with another individual. This 

 example exactly imitated, not only the slow floating 

 flight of Acroea Aganice, but also its invariable habit of 

 settling occasionally, with closely-shut dependent wings, 

 on the projecting twigs of the outermost trees on the 

 edge of the wood. There is reason to believe that the 

 species is rare, as the daily forest-hunting of myself and 

 my Kafir collector for several weeks never resulted in 

 the capture of another example ; nor have I seen one in 

 any collection, either from Natal or the adjoining South- 

 African regions.*

* Siuce this paper was read, I liave seen two examples in the Collection 

 of Mr. Hewitson ; one, from the Zambesi, being similar to the two speci- 

 mens here described, the other, from Natal, larger and with yellowish 

 bands.
