Fourth Group of Species. 
This group differs from others by vein 7 of the forewing terminating into the apex, this being a very 
rare ratio in the Liptenins. Both wings above unicolorously black or blackish without markings or only with 
a diaphanous black discal dot, beneath white or whitish with a distinctly prominent black dot at the apex of 
the discal cell and at least with traces of a fine discal line and a submarginal line. 
L. diversa Baker (63 k). Larger, 27 to 34 mm; the forewing beneath at the costal margin and at the diversa. 
apex watered with brown striae; hinclwing beneath over the whole surface thinly strewn with minute dots 
and striae; both wings beneath with a black line close in front of the margin, and the forewing besides with 
dark discal dots in 2 to 6; the hindwing with a black dot in c. Perhaps only a race of the following. Sierra 
Leone. 
L. ilma is smaller, 18 to 26 mm, and has a pure under surface not speckled or only so at the costal 
margin. -—- ilma Hew. (65 c). Both wings beneath with a large, blackish-grey apical spot which is larger on ilma.

and Uganda. — In simplex Auriv. (64 a) this spot is absent or it is on the forewing only represented by a thick simplex. 
submarginal line; both wings with a dark postdiscal line formed by fine streaks, reaching, however, posteriorly 
only vein 4 on the forewing. Togo to Cameroon, 
13. Genus: MicropentUa Auriv. 
The veins are arranged exactly as in Liptena. The palpi, however, are shorter and their middle joint 
is beneath clad with projecting, bristly hair or scales. The species are all small, of a black or blackish ground¬ 
colour and with white or yellowish markings. 
Review of the Species.

B. Fringes of wings one-coloured without spots. 
a. Hindwing above only with some small, yellowish spots forming a curved transverse row. Forewing 
above with a postmedian, narrow, irregularly curved, yellow transverse band extending from the 
costal margin to vein 2. M. juscula. 
(3. Hindwing above with an orange-yellow median band distinctly expanded in the $ at the proximal 
margin and not reaching the costal margin.

II. Wings beneath without light spots in the basal part and also without spots at the margin, or only with a 
whitish proximal border of the black marginal dots. Hindwing above at least at the proximal margin with 
a yellow median band.
