BHUTANITIS. 247 



and the red and black, blue-spotted band towards the anal 

 angle is extended sub-marginally nearly to the costa of the 

 hind-wings; nearer the base is a red spot on the costa in the 

 female. The hind-wings are very slightly dentated, but are 

 produced into a single long tail at the end of the upper median 

 nervule. The larva, which feeds on Aristolochia, is black, with 

 hair-bearing warts, and resembles that of a Thais. There are 

 two hairy projections on the sides of the neck, besides the 

 retractile fork which we find on the back of the neck of the 

 larvae of all this Family. The pupa has a row of spines down 

 the back ; the head is bifid, and the opposite extremity is 

 obtuse. 



Armafidia i/iaidina, Blanchard, is a large Butterfly, with 

 long and rather narrow wings, found in Western China. It 

 was first brought from Mou-pin by the French missionary, Abbd 

 David, who was the first to make known the natural history 

 treasures of the far interior of China. It measures rather more 

 than three inches across the wings, which are black, cro-sed 

 by slightly undulated thread-like white transverse lines. The 

 hind-wings are black towards the anal angle, with a broad red 

 bar, some blue flecks beyond it, and a few deep orange sub- 

 margmal dashes outside. The hind-wings are dentated, and tlie 

 median nervules terminate in three long tails, that at the end 

 of the upper median nervule being the longest (half as Ion' 

 as the length of the rest of the wing), and spatulate. 



Bhiitanitis lidderdalii^ Atkinson, much resembles Armandit 

 thaidina, and is placed by some authors in the same genus 

 The structural characters appear to be slight, and the colour is 

 much the same, but A. lidderdalii is a considerably larger 

 Butterfly, measuring nearer four inches than three across the 

 wings, which are much broader, and of a much deeper black 

 with whiter striae. On the hind-v/ings the orange-ochreous sub- 

 marginal dashes are replaced by lar^e spots of the same colour.
