already mentioned, the distinction of being the smallest butterfly 

 in India. It looks like a miniature of the last-named species, but 

 the dark bolder to the wings is not so well defined. 



58. Zizern li/shnon, Hiibner (699). 



59. Zizera otis, Fabricius (703). These are both more or leas like 

 the others mentioned of the same genus, are smaller than Z, maha 

 and larger than Z. gaika. 



60. Emrs argiades, Pallas (716). This is a little, bright blue 

 butterfly with silvery underside; near the tail, on the underside of the 

 hindwing, there are some orange markings, below which are a couple 

 of black spots. It is fond of settling on the ground and sucking up 

 the moisture in damp spots. It is found almost all over the world. 



61. Nacaduba ardates, Moore (730). This is a purplish -coloured 

 insect with the underside brownish, marked with fine white waving 

 lines. It is peculiar in having a tailed as well as a tailless form. 

 Just above the tail, when present, on the underside, there is a small 

 black spot marked with greenish scales. 



62. Jam ides bochus, Cramer (733). This is a most lovely little 

 creature, the most brilliant, I think, of all the "blues," and only 

 approached in the depth of its brilliantly metallic lustre by Tajuria 

 longinus, though the blue in the latter has a greener tinge, whereas 

 in J. bochus it is of a deep blue. It is wonderful to see this butterfly 

 flashing among the bushes and trees, looking like a sparkling gem as 

 it darts hither and thither. When it rests it disappears ; but as soon 

 as it rises the flash of colour from the wings reveals its presence, and 

 the beholder is struck with admiration. 



63. Lampides elpAs, Godart (734). The three genera of Nacaduba, 

 Jamides and Lampides are very close to one another, the colours on 

 the upperside of the wings being the chief difference between them . 

 The markings on the underside are very similar, and are disposed 

 in the same manner in each species of the three genera. In Jamides 

 the blue on the upperside is very deep ; in Lampides it is very pale, 

 almost milk-white in some species, while in Nacaduba the shade of 

 colour appears to be something between the other two genera. 



L. elpis is a beautiful insect, the colour of the upperside being a pale 

 though shining blue ; the underside is similar to J", bochus, but paler ; 

 the markings are disposed in very much the same manner.
