This is one of the most common diurnal Lepidoptera, having a wide range through intratropical Asia and 

 the Eastern Islands. We have specimens from various parts of India. Those from Java were chiefly 

 obtained by breeding and are in high perfection. The larva feeds on the Mscliynomene Sesban, and is found 

 abundantly from January to April. The specimens, in whatever country collected, agree closely in their 

 markings, and present no varieties : the distinctive mark of the female, as above indicated, is, as far as my 

 observation extends, permanent, and it is confirmed by the habit of the body. One of the varieties indicated 

 by the authors of the Eucyclopedie is described in the sequel as a distinct species.

Wings above sulphureous, with a common posterior black border, which in the fore-wings is very 

 broad at the apex, whence it passes in a gradual curve beyond the middle of the costa ; at 

 the interior margin it is regularly transverse, and in the medial area it is excavated by a 

 deep notch having an oblique flexuose exterior, and a regular longitudinal inner edge ; in 

 the hinder-wings the border is parallel with the posterior margin, having its inner edge 

 gradually evanescent : underneath bright sulphureous, each wing bearing a simple linear- 

 annulated mai-k on the disk; fore- wings with a large quadrangular violaceous-brown spot at 

 the apex, a smaller oblique blackish mark near the inner apical angle, and a delicate 

 flexuose character of the same colour, near the base ; hinder-wings with two obsolete sub- 

 annular basal characters, an obscure brownish cloud near the middle of the costa, and a very 

 obsolete series of clouded wedge-shaped marks within the posterior margin. 



This insect is distinctly indicated in the Encyclopedie. In that work it is considered as a variety of Terias 

 Hecabe. But it appears from the preceding remarks, that in an extensive series of more than forty specimens 

 of the latter insect, no variation is observed but that arising from the distinction of the sexes. I therefore 

 consider the indication alluded to as a confirmation of our species : according to my research it is clearly dis- 

 tinguished from T. Hecabe, by the breadth and interior outline of the posterior border of the fore-wings above, 

 as well as by the large quadrangular apical spot and the peculiarity of the markings underneath. Our col- 

 lection contains a single specimen in high perfection.
