Larva. — " Slender-cylindrical and smooth, with 2 long curved, diver- 

 gent filaments or soft horns on the head, a single stouter sword-

 ward and serrated on its inner edge and another on the last segment 

 curved forwards and serrated on its outer edge. Colour fine reddish- 

 brown, with a broad green band on the side from the 5th to the last

Genus Apatuea. 

 The best way of subdividing this large genus is by the markings 

 of the underside. In the cell of the forewing there are normally 

 to be found the following spots — a subquadrate spot at the end of the 

 cell, another about the middle, and traces of a third near the base. 

 These are very clearly shown in A. garuda (vide Plate C, 17, 17a). 

 These spots are not always so clearly marked, and in those species in 

 which the outer margin of the cell is incomplete, the lower half of 

 the spot at the end has, as it were, overflowed and become distorted 

 in shape. In practice, however, they can always be traced, and on 

 this basis the genus may be subdivided as follows : — 



1. Species in which the spaces between the spots 



and beyond the cell are white or pale yellow, 

 the dark spots being reduced and almost 

 linear ... ... ... ... ... (IVeptis.) 



2. Species in which the spots are well developed, 



the spaces beyond them being of the generally 



ground colour of the wing or hardly paler ... (Euthalia.') 



On Plate C 3 species of each section are figured. 



(1) A. Neptis. 



Apatura leucothooe, L. — Dark brownish-black. Foreiving: an 

 elongate white spot, filling the greater part of the cell, showing suffus- 

 ed traces only of the median spot, a triangular white spot beyond the 

 cell. A curved band of six to seven quadrate spots beyond it between 

 the veins, but having no spot between veins 4 and 5, a subterminalrow 

 of white spots more or less broken in the middle and sometimes traces. 

 of pale lines before and beyond it : cilia whitish black on the veins.
