African Species of the Genus Neplis. 543 
MAURITIUS. 
Expanse about 38 mm, Ground-colour uniform umber brown. 
. On f.-w. a narrow hind-marginal border very slightly paler followed 
inwardly by a second and sometimes a third slightly paler line. On 
inner margin near angle a small, not always well-defined spot of 
deep yellow, traversed by nervule 1. In areas 2 and 3 deep yellow 
spots forming a large ovate discal mark, its long axis nearly at right 
angles to costa. Three subapical spots of deep yellow forming a 
rather irregular mark in 5, 6, and 8, the middle spot the largest and 
that in 8 the smallest. On h.-w. a discal band of deep yellow almost 
pointed at anal angle, but widened gradually to nervule 4, thence 
somewhat narrower, and barely reaching the costa, its proximal 
edge nearly straight, its distal tending to concavities between the 
nervules. Marginal and submarginal narrow borders somewhat 
paler than ground-colour. 
Underside. Paler and duller ground-colour. In f.-w. a trace of a 
white line across end of cell. In h.-w. the discal band white or 
faintly pinkish, sharply defined proximally, but distally shaded into 
ground-colour and followed by two pale zigzag lines whose angles 
lie on and between the nervules. In the male there is a silky 
opalescent area on inner margin of f.-w. extending to nervule 2. 
Neptis frobenia is not very common in collections. It 
is easily identified and has a very different appearance from 
that of any other species. The male clasper is very like 
that of comorarum. Owing to lack of material | am 
unable to say whether the small differences shown in the 
drawing are constantly recognisable. Aurivillius gives 
Madagascar as a locality for this species, but there appears 
to be no record of its occurrence on that island.
