African Species of the Genus Acraca. 247 



This peculiar form is, so far as is at present known, 

 extremely local. The type was described as from Entebbe, 

 but it has not been received by the Oxford Museum, 

 amongst the many thousand specimens from that locality. 

 The habitat given, viz. Buka Bay, V. Nyanza, is the 

 only quite authentic record I possess. 



A. terpsichore f. rangaUina. PI. V, f. 2 ((J). 



^ . Expanse 44 mm. F.-w. Cell, a small elongated spot at 

 base of 3, basal half of 2, greater part of lb, and central portion 

 of la tawny yellow. Costa and apical half of wing sepia. The 

 nsual subapical patch of ground-colour is reduced to three elong- 

 ated pale ochreous streaks in 6, 5, and 4, that in 6 being only 

 about one-third the length of those in 5 and 4. Submarginal 

 internervular spots of tawny yellow. A little black at base 

 extending outwards along nervure 1 and there expanding into 

 a small dusky spot about 5 mm. from base. A small crimson 

 streak on subcostal near its base. 



H.-w. with a little black at base, central area tawny yellow, 

 hind margin broadly sepia, deeply indented by ground-colour in 

 areas 4 and b. A series of submarginal yellow spots inclined to 

 tawny towards apex. Inner margin paler with two dusky spots 

 in la and one in lb, all more or less coalescent. The subbasal 

 band of red edged with black, so conspicuous beneath, is here 

 faintly indicated. 



Underside, f.-w. as above, but paler and duller, and the dark 

 apical portion blackened only at end of cell, and along outer edge 

 of the tawny yellow in 3 to la. Orange internervular streaks 

 along the margin. H.-w. pale dull ochreous with black nervule 

 ends and bifurcated rays enclosing red marks, the latter inwardly 

 limiting the subtriangular marginal spots of ground-colour. 

 At about the level of end of cell a double row of elongated 

 transverse black spots enclosing red, much as in ventura. A 

 round subbasal black spot in cell. A black spot in 8 and some 

 red in 9. Some irregular black at base. 

 $ . I have not seen a $ of this form. 



The pattern of the upperside of this form is very distinctive 

 and with the exception of the type and co-type in the South 

 Kensington Museum, I have seen no examples at all like it. 

 The genitalia are the same as in tcfpsicJiorc.
