inches in expanse, and have very broad, rounded, hardly den- 

 ticulated wings, the fore-wings being hardly longer than the hind- 

 wings. The species are black, with green or yellow transverse 

 markings, and sometimes white spots ; more or less of the 

 centre of the hind-wings is usually green. 



Indian and Austro-Malayan Regions. 



To these regions belongs the small genus Prothoe, Hubner, 

 the type of which, P.franckii (Godart), is about three inches 

 in expanse, with broad short wings, and the hind-margin of the 

 fore-wings nearly straight, while the hind-wings are angulated, 

 and produced into a short broad obtuse tail at the outer angle. 

 The Butterfly, which is found in Java, is black, with a broad 

 oblique white band edged with blue on the fore-wings ; towards 

 the tip are some white spots. The under-side is brown, varied 

 with grey, and, on the hind-wings, with greenish : it is marked 

 with black spots and zig-zag lines. There are several closely 

 allied forms in Malacca, &c, with the band blue, sometimes 

 without any white admixture. In P.ausiralis (Guerin), and its 

 allies, which are found in New Guinea and the Moluccas, the 

 hind-wings are concave below the middle, and produced into 

 a short broad lobe, but are hardly sub-caudate. These Papuan 

 species of Prothoe are black Butterflies, rather larger than P. 

 franckii, with very broad white or pale yellow bands on the 

 hind-wings, and often on part of the fore-wings likewise. 



The largest and most beautiful species is P. cafydonia, 

 Hewitson. It is more than five inches in expanse, and is 

 found in Malacca and Borneo. It is black, with the base and 

 hinder half of the fore-wings primrose-yellow nearly to the 

 margins, where the colour ends in a zig-zag outline ; nearer the 

 tip is an oblique row of spots of the same colour. The hind- 

 wings are bluish, shading into primrose outside, with a broad 

 black border; the outer angle forms a large rounded lobe. 

 The under surface is black and brick-red, varied with primrose,
