300 Mr. H. Eltringliam's Monograph of the 



Head black with a few whitish marks, thorax black with two 

 anterior dorsal whitish streaks. Abdomen black above with 

 pale yellowish segmental lines and lateral spots. Claws 

 equal. 



9 . Expanse 50-60 mm. Kesembles the ^^ but f.-w. less 

 angulated. 



f. alhimaculata 



Differs from typical examples in having the spots of f.-w. 

 white. At present I have only seen c? (? of this form though 

 $ 5 probably also occur. 



f. angolaniis. • 



Differs from the typical or eastern form in being larger ( ^ 

 60 mm. § 68 mm.). The f.-w, spots are white, in both 

 sexes the ground-colour of the marginal borders in both 

 wings on underside is generally, though not iavariably, pale 

 greyish ochreous. On h.-w. underside areas 8. 9, a streak on 

 lower side of base of cell, areas Ic, lb, and la remain reddish as 

 in typical specimens. 



Lathy describes an aberration of the $ in which the 

 f.-w. spots are tinged with pale yellow and the h.-w, 

 patch is radiated into the marginal black. This would 

 appear to be a not uncommon form, examples agreeing 

 with Lathy 's figure occur both in the Tring Museum and 

 in my own collection. 



I do not think the differences between the Angola and 

 other forms warrant the separation of the former as a sub- 

 species. The f -w. white spots do not distinguish it from 

 the alhimaculata form, and they are not constant as shown 

 by the $ aberration above described. The pale colour of 

 the wing borders on the underside though predominant, ia 

 also not quite constant. The variation of this marginal 

 colour is peculiar. In Angola it is, as stated, usually dusky 

 ochreous. Passing eastwards it gradually becomes darker,, 

 and at Toro and on to the Tiriki Hills it is deep red brown 

 or black. In German East African examples it again 

 becomes paler turning to a rusty red or orange ochreous. 

 The species is easily recognised by the angulated wings 

 and by the peculiar shape of the yellow central patch of 

 the h.-w.
