riERIN.E. 3 



In South Africa the Fapilionidce are not very extensively repre- 

 sented; the known Picrincc numbering nine genera and sixty-one 

 species, and the Papilioninx one genus containing fifteen species. As 

 compared with the Ethiopian region generally, this number falls short 

 of only one genus (Larinopoda in PierincG) ; but it is very much scantier 

 in species, the region yielding about a hundred and forty Ficrince and 

 sixty- two Papilionincc. 



Many of the most perfect cases of mimicry of butterflies of other 

 tribes occm- 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.

I.MAGO. — Ecad small or of moderate size, sometimes rather broad, 

 always more or less hairy, and usually densely so clothed ; eyes round, 

 prominent, smooth ; haustdlum (maxillcc) long ; ^^d/^n compressed, 

 rather short, usually with rather bristly hair beneath, but sometimes 

 Avith 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 ; ayitcnnce usually of moderate length (very long in the genera 

 Lcptalis 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 Leptalis, leucojjJiasia, Terias, and 

 Pontia very short and slender), but moderately robust in some genera 

 (Callidryas, Goncpteryx, Hehomoia, &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 LcpUdis 

 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 

 Leucophasia extremely short). Fore-winys apically rather prominent, 

 sometimes sub-acuminate, rarely (Gonepteryx) shortly and ax3utely fal- 

 cate : subcostal nervure 3- 5 -branched,— the first ner\'ule (occasionally 

 uniting with costal nervm-e) always (except in Leptalis and Leucophasia) 

 —and the second one very frequently— given ofF before extremity of
