DANAID^. 83 



chiefly tropical and oriental, are known : but from South 

 Africa I can only discover that four species, belonging to two 

 Genera, have been recorded. These are insects above the 

 middle size, no specimen of either of the four species that 

 I have seen expanding under 2 inches 9 lines. While in the 

 Pieridce the typical arrangement of colouring consists of a 

 light ground-colour with dark spots and borders, in the 

 Danaidce it is just the reverse, ochreous and white mark- 

 ings contrasting with velvety-brown and black ground- 

 colours.* The flight of the species of this Family is usually 

 rather slow, but it can be considerably quickened when occa- 

 sion demands. The Genera represented in South Africa are 

 Euplcea and Danais ; of which the former comprises but 

 one, the latter three, species. 



Genus EUPLCEA. 



Euploea, Fab. 



IMAGO. Antennae, rather long (longer than in Danais}, 

 and with the club rather more gradually formed. Fore-wings 

 elongate, but not so markedly produced in apical portion as 

 those of Danais ; costa a little more arched ; hind-margin 

 scarcely concave in its central portion ; inner-margin slightly 

 concave about middle, convex near base. Hind-wings large, 

 rounded ; hind-margin very slightly dentate. Head and 

 thorax white-dotted. 



LARVA. Three pairs of tentacles on the anterior segments 

 of the body ; one pair on the penultimate segment. 



PUPA. Smooth, rounded, constricted as described above 

 (under Danaidoe). 



Only one species of Euplcea is known as South African ; 

 others so mentioned belonging more strictly to Danais. It 

 is a sombre- coloured, dark -brown Butterfly, differing strik- 

 ingly from the brilliantly-gilded Chrysalis that it emerges 

 from. 



53. Euplcea Goudotii. 



Euploea Goudotii, Boisd., Faune Ent. de Mad. Eourb. et 



[Maur., pi. 3, f. 2. 



Expands 3 in. 6 lin. 3 in. 7 lin. 



Dark-brown ; becoming paler towards hind-margins. Fore- 

 wing : a whitish spot on costa beyond middle, just above 

 extremity of discoidal cell ; a similar spot a little beyond and 



* The species of Idea Hestia of some authors form an exception to 

 this statement. None, however, are found in South Africa.
