except that NeoJmle, like Ilortn, possesses some short 

 reddish rays at the apex of the lore-wings, which appear 

 to be wanting in Mahela. The fore-wing spots appear 

 to be less constant in the $ Neolndo than in the $ . 



Mr. Bowker's specimens are from Maseru. I have exa- 

 mined examples of Neobule taken in Damara-land by 

 Mr. J. A. Bell, in the Cape Colony (Kenhart and Coles- 

 berg) by Dr. Chittenden and Mr. A. F. Ortlepp respec- 

 tively, in the Trans-Vaal (Potchefstroom) by Mr. V. E. 

 Noreu, and in Natal (D'Urban) by Mr. McKen and 

 myself. 



[At the British Museum, Neobule is uow regarded as only a variety of 

 Mahela. Probably Horta, Mahela, and Neobule are but one slightly 

 varinlile species.— Sec. Ent. Soc.]. 



Acrcea natalica. 



Boisduval, App. Yoy. de Delegorgue dans FAfr. aust. 

 p. 590 (1847). 



In my Rhopalocera Africce austraiis, pp. 97-98, 1 treated 

 A. natalica as a variety of Uypatia, but at the same 

 time pointed out numerous marks of distinction between 

 the two forms. Subsequent investigations, and the 

 observation of natalica in life, have convinced me that 

 Boisduval^s species is well founded. 



A single ? specimen, sent by Mr. Bowker from 

 Maseru, seems to be referable to this species. It is 

 considci'ably smaller than usual, expanding only 1 in. 

 62 lin. ; the spots are smaller and less numerous, and the 

 hind-marginal border of the hind- wings, as well as the 

 apical one of the fore-wings, is not nearly so broad. In 

 the forc-wimjs, the transverse costal stripe beyond the 

 cell consists of but three small separate spots, instead of 

 four rather large sub-confluent ones ; the spot immedi- 

 ately below these is scarcely perceptible ; and the two 

 minute submarginal spots, generally well-marked on 

 either side of the first median nervule, are wanting. In 

 the hind-u'ings, there is a conspicuous discal white suffu- 

 sion* towards the inner margin, covering the outer third 

 of the discoidal coll, and extending a little above and be- 

 yond it ; only four of the usual eight spots of the discal row 

 are present, viz: the two next the inner margin (which 

 are indistinct), a small one just beyond the end of the 



* This suffusion of white is present, in a less degree, in an indubitable 

 <J of Natalica tf^ken by Mr. Bowker on the Bashee River, Kaffraria.
