In Sontli Africa the Fapilionidce are not very extensively repre- 
sented; the known Fierinm numbering nine genera and sixty-one 
species, and tlie Papilionince one genus containing fifteen species. As 
compared with the Ethiopian region generally, this number falls short 
of only one genus {Larinopoda in Pierinm) ; but it is very much scantier 
in species, the region yielding about a hundred and forty Fierince and 
sixty-two Papilionince. 
Many of the most perfect cases of mimicry of butterflies of other 
tribes occur in this Family, as well as a certain number within the 
limits of the Family, Sub-Family, or even Genus itself. These will be 
found more particularly referred to under the several subdivisions and 
species concerned.

Imago. — Head small or of moderate size, sometimes rather broad, 
always more or less hairy, and usually densely so clothed ; eyes round, 
prominent, smooth ; hcmstcllum (maxillai) long ; pa/pi compressed, 
rather short, usually with rather bristly hair beneath, but sometimes 
with lengthened scales, — basal joint much developed, never shorter, 
and usually twice (sometimes thrice) as long as the second one, — ter- 
minal joint always small, seldom as long as the second, and frequently 
minute ; antennae usually of moderate length (very long in the genera 
Leptalis and Euterpe) ^ with an elongate-ovate club, but in many cases 
shorter and thicker, with a very gradually-formed blunt or truncate club. 
Thorax usually not large (in Zeptalis, Leucophasict, Terias, and 
Pontia very short and slender), but moderately robust in some genera 
{Callidryas, Gonepteryx, Rehomoia, &c.), often with long dense silky 
hair above. Wings large (the hind- wings mostly larger in proportion 
to the fore-wings than in other groups, — in some species of Leptalis 
actually twice as large as the fore-wings), usually of moderate thick-' 
ness, but in the slender-bodied genera very thin, and in the stout- 
bodied ones of considerable thickness ; discoidal cell always closed (in 
Lencophasia extremely short). Fore-wings apically rather prominent, 
sometimes sub-acuminate, rarely {Gonepteryx) shortly and acutely fal- 
cate : subcostal nervure 3— 5 -branched, — the first nervule (occasionally 
uniting with costal nervure) always (except in Lcp)tcdis and Lencophasia) 
— and the second one very frequently — given off" before extremity of
