African Species of the Genus Neptis. 557 
markings.. F.-w. with three small white spots in cell and four beyond 
it. A very small inner marginal spot not always extending beyond 
la. A large patch of two spots in 2 and 3, its proximal and distal 
margins forming nearly parallel lines at right angles to the costa. 
A rounded spot in 5, a subquadrate in 6, and a very small spot in 8. 
H.-w. with a discal white band about 5 mm. wide beginning about 
middle of inner margin and ending, considerably reduced in width, 
in area 6. All fringes white between nervules. 
Underside chestnut brown. White markings as above, but with 
an extra subapical spot on costa. The h.-w. discal band outlined 
with darker colour. 
The principal distinction between this species and incon- 
grua is the presence of white spots in the f.-w. cell, and the 
large coalescent spots in f.-w. 2 and 3. Whilst the external 
characters suggest a very close relationship to imcongrua, 
the male clasper is so different from that of the other species 
of the group as to suggest only a very slight affinity. That 
the clasper of cncongrua should present a far closer resem- 
blance to that of nemetes than to that of swynnertoni is a 
good example of the difficulties presented by this genus. 
Trimen (/. c.) regards this species together with incongrua, 
exaleuca, and woodwardi as allied to the Palaearctic species 
lucilla Fab. 
swynnertoni neavei. 
Whilst the type of this form in Lord Rothschild’s col- 
lection differs in certain small points from the few examples 
of swynnertont we have at Oxford, examination of a small 
series of Mlanje specimens in the national collection shows 
that such differences are not constant. Perhaps the least 
inconstant feature is the absence of well-marked inter- 
nervular rays on the h.-w. underside in neavet. 
I strongly suspect that when Lord Rothschild described 
neavet he had not seen an example of swynnertoni, otherwise 
he would not have compared it with exaleuca, with which 
it has little in common. Indeed, it is difficult to separate 
neavei from swynnertoni on any outward character, but 
the fact remains that the male armatures are different, 
at least according to the few preparations I have been able 
to make from these rare forms. 
The clasper of swynnertoni is shown at Pl. XXIV, fig. 12. 
Those of examples from Mlanje (= neaver) differ in having 
an upturned hook at the extremity, somewhat like that of
