African Species of the Genus Acraca. 118 



on costa. H.-w. pinkish ochreons, basal portion of areas 7, 6, 5, 

 distal end of cell, and median part of Ic, lb, and la rose- 

 pink. Black hind margin deeply edentate on nervules, edged 

 inwardly with deep orange, and bearing seven ochreous inter- 

 nervular spots. Black spots as on upperside and three 

 additional basal spots visible in 8, at base of cell, and in Ic. 

 Head black with orange tufts on collar. Thorax black with two 

 whitish dorsal lines, orange lateral spots, and ochreous spots 

 beneath, basal half of abdomen black with lateral orange spots 

 remainder orange. Claws unequal. 



9 . Expanse 56-60 mm. Sepia black. F.-w. spots as in ^ 

 (spots sometimes smaller). An oblique white subapical band in 

 6, 5, 4, and 3. H.-w. usually without basal suffusion. Black hind- 

 marginal border with internervular quadrate spots of the some- 

 what paler groimd-colour. 



Underside f.-w. greyish mauve ; coeta, apex, and hind margin 

 sage green with black nervules and rays. Spots often smaller, 

 those near base may be very minute. H.-w. sage green spotted 

 as in ^. Head and thorax black with dor.sal and lateral 

 greenish white spots. Abdomen black above, pale ochreous 

 beneath, with lateral white and sublateral pale ochreous spots. 



A. cepheus f. ahdera, Hew. 



Differs from the typical form in the absence of the red 

 colour from the space between the end of cell and discal row of 

 spots, and there is sometimes a trace of a whitish subapical bai. 



A. cephe\is f. eginopsis, Auriv. 



The red in f.-w. forms a median hind-marginal patch, giving 

 an appearance similar to that in A. egina. 



A. cepheus 9 f- pheusaca, Suffert (= abclera '^ , Auriv.). 



The ground-colour of the wings is brownish red, the spots are 

 obsolescent, the costa, apex, and hind margin reddish brown, and 

 the subapical bar dark ochreous. The h.-w. spots small and 

 often obsolescent. The marginal border bears slightly paler 

 internervular spots. Underside f.-w. as above but paler ; costa, 

 apex, and hind margin brownish ochreous. H.-w. pinkish 

 brown, spots as in typical examples. 



Aurivillius associates this form of 9 more particularly with 

 the ahdera form of the ^ , but I do not think it is the only $ 

 form occurring witli the ahdera ^ . 



A. cepheus 9 f- sucepha, Suffert. 



In this form the ground-colour is nearly as bright a red as in
