1 66 LLOYD'S NATURAL HISTORY. 



pupae are armed with a row of strong spines on the ventral 

 surface. 



This is one of the most extensive and characteristic genera 

 among those inhabiting the Indo- and Austro- Malayan Regions, 

 to which it is exclusively confined. Notwithstanding its close 

 structural affinity to Pereute, there is little outward resemblance 

 between the genera ; for Delias^ notwithstanding the many 

 forms which it assumes, has always the unmistakable appear- 

 ance of a true Pierid. Most of the species are black above, 

 varied with bluish-grey, and often marked with red or yellow 

 at the base or on the hind-wings beneath ; or they are white, 

 more or less bordered with black, and with the hind-wings 

 bordered beneath with a row of red, orange, or yellow spots, 

 or banded with red. They have a weaker flight than would be 

 supposed from their appearance, and are easily captured. 



I will first discuss the species which I have figured to illustrate 

 the genus, and will then proceed to notice some of the more 

 interesting forms which are not figured in the present work.

This species, which is common in Java and Sumatra, 

 measures about two inches and a half across the wings. The 

 male is yellowish-white above, with the costa and apex of the 

 fore-wings, and the hind-margin of the hind-wings rather broadly 

 black. The female is ochreous-yellow, with very broad black 

 borders. The under side of the fore-wings is black, with a 

 whitish streak at the end of the cell, and a row of four or Eve 

 white or yellow spots towards the tip. The hind-wings are 

 orange-yellow beneath, with a red streak, bifid at the end, at
