POLYOMMATUS. 433 



cell, not extended above or below it, five beyond ; the first two of 

 the latter group broken at veins 2 and 3, the lower portions 

 shifted imvards out of line with the upper portions, the next 

 short, not extended below interspace 3 and narrowed to a point 

 posteriorly; the subterrainal two entire, curved, the outer one 

 macular. None of the fasciae extend quite up to the costa. Hind 

 wing : transversely crossed before the terminal markings by eight 

 or nine pale brown fasciae similar to those on the fore wing but 

 more or less fused and broken and the inner ones posteriorly 

 curved upwards ; these are followed by a comparatively broad 

 band of the ground-colour, an inner subterminal pale brown 

 broad fascia and an outer series of similarly-coloured spots ; these 

 markings posteriorly interrupted by a black spot in interspace 1 

 and another in interspace 2, the latter inwardly margined with 

 ochraceous ; both spots with superposed metallic bluish-green 

 scales. Antennae, head, thorax and abdomen brown ; the shafts of 

 the antenna? ringed with white, the thorax with some bluish- 

 white pubescence ; beneath : the palpi, thorax and abdomen 

 white. $ . Upperside : brown ; in some specimens with, in others 

 without, some iridescent bluish scaling at the bases of the wings 

 which sometimes extends outwards towards the disc. Fore 

 wing : auticiliary black lines, and in a few specimens traces of an 

 inner subterminal series of bluish spots in the interspaces more 

 obvious posteriorly than anteriorly. Hind wing: a postdiscal 

 transverse pale fascia, often absent and always more obvious 

 anteriorly than posteriorly, followed by a subterminal series of 

 white-ringed spots, the posterior two of which are jet-black and 

 always present ; the anterior spots brown, of a shade slightly 

 darker than the ground-colour and not always present, though in 

 most specimens fairly well indicated ; lastly, a prominent anti- 

 ciliary black line. Cilia of both fore and hind wings white with a 

 line of brown along their bases. Underside : as in the c? . 

 Antennae, head, thorax and abdomen similar to those of the c? 

 but paler on the upperside.

Hob. That of the genus, of which it is the sole representative. 



Larva. " When full-grown measures j 7 ^- of an inch in length ; 

 pale, dull green throughout, slightly shagreened but not hairy 

 except slightly so at the sides : the small retractile head smooth, 

 ochreous pale brown, shining ; a dorsal line of a somewhat darker 

 green than the ground (colour), no other markings whatever, 

 altogether a very plain looking creature. The constrictions at 

 the segments shallow, the spiracles black but inconspicuous, the 

 usual extensile organs on the twelfth segment very short. 

 Larva feeds on the yellow pea-like flowers and on the pods of 

 Crotalaria striata, DC., in Calcutta. Dr. A. Forel, of Geneva, has 

 identified the three species of ants which I have found attending 

 this larva in Calcutta as Camponotus rubripes, Drury (sylvaticus, 

 Fabr.), subspecies compressus, Fabr., Tapinoma melanocephalum, 

 Fabr., and Prenolepis obscura, Mayr (var. clandestina, Mayr)."
