with broad black-edged fulvous bands. Fore wing white ; the 

 costal area tinged with fulvous and irrorated with black ; oblique 

 subbasal and antemedial black bands, tinged with fulvous from 

 cell to inner margin ; an indistinct fulvous spot in cell, and black 



spot at upper angle ; a very- 

 oblique fulvous-tinged black 

 bancl, curved from the costa 

 near apex to lower angle 

 of cell, then straight. Hind

 Fig. 115.— Nymphula fluctuosalis, $. §. margin, where it is nearly 



joined by a very oblique line 

 from costa beyond middle ; both wings with a slightly curved 

 oblique black-edged fulvous postmedial band, a black line near the 

 margin, a fulvous marginal band and black line at base of cilia. 



Prof. Wood-Mason described and figured as oryzalis the larva and 

 pupa of an aquatic species which is probably fluctuosalis. Larva 

 whitish ; the head with a few long hairs and five ocelli on each 

 side in a crescentic form ; the somites with a few stiff setae and 

 with four longitudinal series of delicate white filaments acting as 

 tracheal gill-tufts, arranged in groups of two to four filaments, 

 two of the series being above the spiracles and two below. It is 

 very destructive to rice-crops in Burma. 



Pupa fusiform and pale brown, with the stigmata of the three 

 first abdominal somites large and nipple-like and open to the air- 

 chamber of the cocoon. 



Hab. Throughout the tropical and subtropical zones, on the 

 north to Formosa and the Sandwich Islands, on the south to 

 Australia. Exp. 16-20 millim.

pi. 174, fig. 4 ; CSf S. no. 4402. 



Differs from fluctuosalis in the ground-colour being brown ; 

 abdomen ringed with black, but without fulvous bands ; wings 

 without any of the fulvous markings, which are replaced by black. 

 Fore wing with the line from costa beyond middle not so much 

 bent inwards to angle of cell, finer towards inner margin, and on 

 hind wing further from the antemedial line ; both wings with the 

 postmedial band diffused and fuscous ; the cilia fuscous. 



Hab. Calcutta ; Nilgiris ; Ceylon ; Eangoon. Exp. 16 millim. 



4641. Nymphula leucostola, n. sp. 



<j . Differs from votalis in the ground-colour being pure white ; 

 the head brown; abdomen ringed with brown and with brown 

 bands on the subbasal and subterminal segments. Fore wing with 

 the costal area suffused with brown ; the subbasal and antemedial 

 lines obsolescent ; the line beyond middle fine and evenly curved ; 

 both wings with the-diffused postmedial band brown and prominent;
