150 LLOYDS NATURAL HISTORY. 



The genus Catuna, Kirby, is peculiar to Africa, and is 

 rather varied in colouring, though not numerous in species. 

 These Butterflies measure about two inches across the wings ; 

 some resemble the genera Hamanumida or Aterica, in shape 

 and colour, being brown, with large black spots, and buff mark- 

 ings ; while C. canobita (Fabricius) resembles a large Neptis, 

 with markings of a slightly bluish-white ; but the sub-marginal 

 markings of the fore-wings are in the form of white arrow-heads. 



Some of the remaining genera much resemble the Indian 

 genera allied to Euthalia, Hiibner, but of these Schatz and 

 Rober make a separate group, chiefly on account of the great 

 dissimilarity of the larvae. 



Hamanumida dcedalus (Fabricius) is a very common African 

 Butterfly, not remarkable for its size or beauty, but for the 

 peculiarity of its coloration. It is scattered all over with 

 white spots on a pale brown ground, very much after the 

 fashion of a Guinea-fowl, a bird found in the same countries. 

 .The under side is ochreous-yellow, with more or less distinct 

 white spots. The Butterfly is said to resemble Pyrameis cardui 

 in its habits, and often to settle on the ground. It has been 

 stated that its colour, which varies a little, is assimilated to 

 that of the soil in the different localities in which it is found. 

 It measures rather more than two inches across the wings. 



Of the remaining African genera, four are rather numerous 

 in species, and all are peculiarly characteristic of the Fauna of 

 Tropical Africa. In southern Africa they are hardly repre- 

 sented, and what is more singular, one genus only is repre- 

 sented, by a single species, in Madagascar. 



The genus Aterica^ Boisduval, includes species of moderate 

 size, measuring two inches or more across the wings. The 

 fore-wings are short and the hind-wings rather long and some- 

 what narrow, the hind-margin not being rounded, but some- 

 what contracted, The type A. rabena, Boisduval, the only
