African Species of the Genus Acraea. 265 



end of cell to position of white subapical marks. The reddish 

 areas visible as above but paler. Costa dusky ochreous with 

 a black spot at base. Apical and hind-marginal area dusky 

 ochreous striated by the black nervule ends and rays. Only a 

 trace of the white subapical marks. 



H.-w. Almost uniformly ochreous, a trace of a greenish 

 tinge about base and on hind margin. Black spots as follows : 

 — One in 9, one iu 8, two in 7 ; the second well beyond end of 

 cell, but not over spot in 6. One in 6 and 5 (one below the 

 other and about 4 mm. from base of those areas). One at base 

 of area 5 on discocellular, one (very small) at base of area 4, two 

 in cell, the second (large) at the level of origin of nervule 2. 

 One ill area 4 just beyond its base, and a row of four large spots 

 in a straight line from end of cell to inner margin in 3, 2, Ic 

 and lb. A basal and a subbasal in Ic, a subbasal in lb, and 

 two spots in In. The ends of nervules are laterally somewhat 

 powdered with brown, but not the internervular rays. 

 A . orina f. nigroupicalis. 



This form, described by Aurivillius, differs only by the 

 absence of the discal red marks in the f.-w. An example from 

 Fernando Po is in the Oxford Museum. Aurivillius' specimen 

 is from Kitta, Cameroon. Many Entebbe specimens exhibit the 

 same variation. 



A. orina f. orinata. 



The difference between this and the type form is thus de- 

 scribed by Oberthiir : — On the upperside the reddish brown spots 

 beyond cell are nearer to the cell. Beneath the h.-w. has two 

 spots ovitside the cell which are not present in orina. Oberthiir 

 further remarks that the h.-w. hind margin is yellowish instead 

 of reddish as in orina, but he was probably judging of the latter 

 by the colour of the original figure, which is, in fact, redder than 

 the actual type specimen, which I have examined. The differ- 

 ences are so slight as to make the name scarcely worth preserving. 

 A. orina orineta, subsp. 



^ . Expanse 50-64 mm. F.-w. dark sepia. Nearly the whole 

 of the cell (in which there is a black indentation on subcostal 

 near the middle), and lb, and the basal half of 2 and 3 red, 

 separated only by the rather widely black nervules. In 6, 5 

 and 4, just beyond cell, broad red streaks separated only by the 

 nervules. On apex and hind margin black internervular rays 

 rather conspicuous. 



H.-w. red with a well-defined sepia black basal area on which 

 basal and subbasal spots are just visible. This black area extends
