already been considered by Professor Poulton.* He points 
out the great influence which the Papilios of the zenobca 
group have had in respect of this character. 
It is interesting to note that this group of Papilios is 
well represented in the collection, comprising the following 
species :— 
P. homeyeri, Plotz. — . 39 specimens. 
P. cynorta, Fabr. 8 cs 
P, peculiart is, Neave . ; 1 5 
P. zenobia, Fabr. : : 49 & 
P. gallienus, f. whitnalli, Neave 6 - 
As Professor Poulton has pointed out, Joc. cit, p. 489, in 
P. gallienus and its allies, the basal patch is very large and 
is traversed by black lines instead of spots, a character not 
occurring in Planema. In the other species the area is 
smaller and the lines replaced by spots. This condition 
reaches its extreme in P. peculiaris, mihi 2, which, as will 
shortly be shown, is an extraordinarily close mimic of 
Planema paragea, Grose-Smith. P. homeyervis also remark- 
able for the fact that the colour of this patch is more 
chocolate-brown in colour instead of golden-brown as in 
other species. In this respect it approaches P. godmani 
and P. tirikensis mentioned above. 
Neptis agatha, Stoll (47), and its allies may also be not 
improbably members of this group. This species exhibits 
in common with other species of the Ethiopian region a 
concentration of the white markings on both wings, as 
Professor Poulton has already pointed out,t in contrast to 
the broken character of these markings in Oriental species. 
The flight of these species is also singularly slow and 
floating when undisturbed and much like that species of 
Planema and black and white Amauwris. 
The variable A. psyttalea, Plotz (81), from many localities 
was accompanied by its equally variable mimic Hypolimnas 
dubius, Pal. (9), in the more western localities.
