African Species of the Genus Acraea. 43 



A large transverse black spot about middle of cell. An irre£fular 

 band of black spots ci'ossing the discal area at the discocellular 

 nervules and extending to the hind angle. Apical area and hind 

 margin rather broadly dusted Avith black and bearing eight rather 

 suffused spots of the ground-colour. H.-w. black at base and 

 slightly dusted with black on margin. A very minute black dot 

 at point where nervure 5 leaves the cell. An irregular zigzag 

 discal band of black extending from the costa to the anal angle. 

 Thorax black, spotted witli pale brown beneath. Abdomen black 

 above, brown beneath, and l^earing segmental spots of pale brown. 

 Claws unequal. 



The underside resembles the upper but has a A'itreous surface 

 and the markings are less distinct. 



$ . I have seen only two 5 5 of this species. One is in the 

 general collection of the Berlin INIuseum and differs from ^ 

 examples only in the fact that in the f.-w. the space between the 

 central bar and the apical brown is transparent. 



The other is in Mr. J. J. Joicey's collection and resembles 

 the (^ but is larger, paler, and duller. 



Acrea zonatrc appears to be a rather rare insect. The 

 type in the Hewitson collection was taken at Zanzibar. 

 The example figured by Grose-Smith is from Mombasa, 

 one specimen in the Oxford collection is from Rabai, whilst 

 the Tring collection contains examples from Dar-es-Salaam 

 and Pemba I., and the British Museiim specimens are from 

 Zanzibar and Witu. A. zonafa is certainly closely allied to 

 rabbaiae. The claspers in the ^ armature are without the 

 large processes so characteristic of that species.
