86 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, 



A female from the Okavango River is the largest I have yet 

 measured, expanding 1 in. 7 lin. The species is widely distributed 

 over extra-tropical South Africa, and is also recorded from Kinsembo, 

 a little to the 'N. of Ambriz in Angola.

Okavango River (December). One male example. 



This species, so isolated in colour and marking, seems to be 

 remarkably rare, although known to occur at widely-remote spots, 

 such as Lakes Nyanza and Nyassa in tropical, and Swaziland and 

 Natal in extra-tropical South Africa. From the latter region of the 

 continent I have seen but one individual, but have been authentically 

 informed of the occurrence of five others.

 5 . Exp. al. 1 in. 7 lin. 



Dull brownish red, with a common terminal hind-marginal fuscous 

 line; cilia short, whitish. Fore wing : just at extremity of discoidal 

 cell a good-sized rather indistinct quadrate ochre-yellow spot ; a 

 little beyond it a transverse series of five smaller spots of the same 

 colour, lying between subcostal nervure and first median nervule, 

 of which the third (between lower radial and third median nervules) 

 is nearer hind margin than the rest, and the fifth (lowest) is smallest 

 and most indistinct. Hind wing : traces of three very indistinct 

 ochre-yellow spots, one at extremity of discoidal cell, and two (very 

 small) beyond it ; anal-angular portion much elongated and produced, 

 with a very prominent broad terminal lobe, fuscous, with bronzy- 

 greenish scales ; at extremity of submedian nervure a moderately- 

 long rather stout tail, of the ground-colour. [Tail on 1st median 

 nervule wanting, but probably present in uninjured examples.] 

 Underside. — Brownish ochre-yelloio, loith good-sized, rounded, 

 thinly ferruginous-broum-edged ochre-yellow spots ; in both wings, a 

 terminal discocellular spot, and an irregular discal series of contiguous 

 spots, also a series of separate spots along hind margin. Fore wing i 

 in discoidal cell two spots, one subbasal, the other median ; inner- 

 marginal border dull pale yellowish ; six spots in discal series, of 

 which the third (between lower radial and 3rd median nervules) is 

 beyond, and the sixth (imperfect, and below 1st median nervule) 

 before, the rest ; seven spots in hind-marginal series. Hind wing : a 

 subbasal series of four circular spots, of which the 2nd is in discoidal 

 cell, and the 3rd (between 1st median nervule and submedian 

 nervure) is considerably beyond the rest ; nine spots in discal series, 

 of which the 2nd, 3rd, 4th, and 8th are more or less beyond the 

 rest; in hind-marginal series six separate spots, succeeded (below 1st 

 median nervule) by three confluent into one ; some metallic-greenish 

 scales on extremity of anal-angular lobe, preceded (below submedian 

 nervure) by a small dull crimson spot.
