1 88 LLOYD'S NATURAL HISTORY. 



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, Hiibner, 

 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. australis (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. calydonia^ 

 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,
