 greatly to be regretted that T. jerdoni has never been collected again, so 

 far as can be judged by published accounts, since Jerdon first procured it.

 (With Plates VIII and IX.) 



In December last, the Indian Museum received from Mr. F. W. Bour- 

 dillon of Trevandrum, a small collection of diurnal Lepidoptera, amongst 

 which was a much worn and tattered example of a female insect evidently 

 closely allied to the North Indian P. Castor and to the Burmese P. Mahadeva, 

 with the same sex of the latter of which it turned out on examination to 

 agree in having the discal markings of the hind-wing confined to the 

 median region of the organ, where they form a transverse band of lanceo- 

 late spots, instead of being diffused over the whole disk and extending into 

 the cell, as in the former. 



About a month ago, a few species of butterflies Avere received from 

 Mr. G. H. Kearney of the Berkodee Coffee Estate, KojDpa Anche, Mysore, and 

 amongst them is a fine specimen of the male, which proves that the species 

 is, as the above-mentioned female specimen had already indicated, moi'e nearly 

 related to P. Mahadeva than to P. Castor, and enables me to describe it. 



Papilio Deatidaeum, n. sp., PI. VIII, Fig. 1, S . 



Allied to P. Castor and to P. Mahadeva,-\ but more closely so to the 

 latter, with which it agrees in the form of the wings in both sexes. 



Sexes alike, having not only the same form of wings but also the 

 same general type of coloration as the females of the two described 

 species ; the male differing from the female only in the darker and richer 

 tints of its upper surface. 



S . TJPPEKSIDE rich fuscous of a much lighter shade than in P. Cas- 

 tor, or even than in P. Mahadeva, and more densely powdered with fulvous 

 scales than in either. Anterior wing with the basal area of a richer and 

 darker shade of brown than the rest of the organ ; with four distinct 

 longitudinal lines of fulvous scales in the cell, at the extremity of which is 

 a minute but distinct cream-coloured .speck ; with the outer portion beyond
