African Sjyecies of the Genus Acraea. 209 



Elack spots as follows : — One in cell before origin of nervnle 2, 

 and one on discocellulars, one in 3 about 3 mm. from end of cell, 

 one in 2 near its base, and beneath it but nearer margin a spot 

 in lb. In the same area a spot nearer base beneath that in 

 cell. 



H.-w. Ground-colour same as in f.-w. but slightly darker in 

 shade, spotted with black as on the J underside. A black hind- 

 marginal border narrower in the middle than at ape.x and anal 

 angle, its inner edge sometimes dusted with pale ochreous 

 scales. 



Underside f.-w. dull ochre-jellow, costa orange, subapical 

 area pale yellow. Black spots as on upperside but smaller, and 

 sometimes a trace of a discal spot in area 5. Black nervule ends 

 and crimson marginal spots as in $ . 



H.-w. as in ^ . 



The type $ of this species is slightiy aberrant, having 

 three white dots in the h.-w. and no red marginal spots in 

 f.-w. It differs in these respects from other Angola speci- 

 mens, and from those obtained near L. Bangweolo by 

 Neave. The species, as Neave has pointed out, bears 

 a greater resemblance to members of the S. American 

 genus Actinotc than to any African Acraea, especially as it 

 has a rudimentary nervule between la, and lb in the 

 h.-w. It is described as frequenting marshy places and 

 having a very weak flight. The integuments are tough, 

 and if squeezed it exudes a green juice. I have observed 

 that the males are peculiarly liable to become "greasy." 

 The underside of the h.-w. is exceedingly beautiful, having 

 the appearance of being cut from a thin sheet of metal, 

 whilst under the microscope every scale exhibits a beauti- 

 ful iridescence recalling the appearance of the well-known 

 diamond beetle.
