lowish and a black iris. Anal angle with a geminate spot com- 

 posed of black and white atoms. 



Head, thorax and abdomen fuscous. 

 In the collection of the British Museum, &c. 

 This species seems to be the representative of Th. Odana in 

 Northern India, and does not seem to be rare. The blue is of a 

 peculiar brilliancy. 



Fam. PAPILIONID^.. 

 Genus Papilio. 



P. Evan. P. alls anticis elongatis falcatis acuminatis, posticis elon- 

 gatis, dentatis, caudatis, omnibus luteo-rufis, margine externo 

 late fusco-brunneo, maculis lunulisque luteo-rufis. Exp. alar. 

 5 unc. 1 lin. vel 130 millim. 



Anterior wings elongate, falcate, acuminate, of bright light 

 fulvous, the base and anterior portion of the costa more ob- 

 scure, the costa from the middle to the apex and the exterior 

 margin deep brown, with fulvous spots at the apex and anal 

 angle ; a sigmoid spot in the cell and a larger spot on the disco- 

 cellular nervure of the same colour as the margin. Posterior 

 wings elongate, dentate, caudate, light fulvous at the base, deep 

 fuscous brown beyond ; a series of five lunulate light fulvous spots 

 near the outer margin, preceded by three spots and a striga of a 

 deeper fulvous near the anal angle, the tail fulvous brown, paler 

 towards the apex ; cilia marked with pale fulvous near the outer 

 angle. Below, the wings a bright yellow-ochre colour, the ante- 

 rior with several irregular spots in the cell, a larger one on the 

 discoidal, three on the costa near the apex, a fourth below the 

 last of these, followed by a zigzag line, and the outer margin 

 bright brown : the margin is marked with lighter-coloured clouds, 

 and preceded by some indistinct spots on the nervures more or 

 less confounded with it. The posterior wings have four brown 

 spots at the base, a broad band beyond the middle of deep rich 

 brown, extending along the abdominal margin to the tails, which 

 are brown. This band is marked anteriorly between the nervules 

 with silvery atoms, those nearest the inner margin forming a sil- 

 very lunule. Beyond the band the wings are of the same colour 

 as at the base, with four sigmoid spots, a narrow line on the 

 margin itself, and the cilia at the ends of the nervules rich 

 brown. 



Head and antennae brown. 



Thorax bright shining black, covered at the sides with brown 

 hair and scales, apparently naturally almost bare on the disc. 



Abdomen very pointed, luteo-fulvous. 



This beautiful species, figured on the second plate of my Ge- 

 nera of Diurnal Lepidoptera, is closely allied to P. Payeni of Van
