362 MR. H. H. DRUCE ON THE [June 2, 



row of exceedingly minute indistinct lunules, and a submarginal row 

 of very narrow crescent-shaped lunules. The bands on the hind 

 wing arranged much as in N. amaura and other allies, and the 

 lunules as in fore wing. 



Female. Upperside as N. amaura. Underside pure white, so that 

 the borders to the light brown bands described in the male are in- 

 visible, and the submarginal rows of lunules appear more distinct. 



Head, thorax, and abdomen brownish, antennae annulated with 

 white ; legs white, with a few black spots. 



Expanse, c? $ 1^ inch. 



This species may be readily distinguished from its allies by the 

 white appearance of the underside. 



Nacadtjba keiria, sp. n. (Plate XXXI. figs. 13 c?. 14 $.) 



Male. Upperside dark lavender-blue, with two or three large indis- 

 tinct triangular marginal black spots at the anal angle of hind wing ; 

 cilia dark brown. Underside clear greyish white, suffused at the 

 base with bright green and with all the markings well defined. 

 Fore wing with two small blackish dashes about the middle of the 

 cell, one above the other, having their respective bases, one on the 

 upper and one on the lower wall of the cell ; a long narrow light 

 brownish streak at the end of the cell and beyond that an irregular 

 band, the upper part consisting of separated spots, the lower usually 

 being a thickened streak ; beyond this is a darker, submarginal, 

 zigzag line and a marginal row of somewhat triangular dusky 

 lunnles. Hind wing with three black, white-ringed, distinct spots 

 encircling the base, viz. one on the costa, one about the middle, and 

 one on the inner margin close to the base ; a rather long narrow 

 band at the end of the cell, bent outwards ; beyond these, com- 

 mencing with a dark spot on the costal margin, a much-broken 

 light brown band, consisting of darker-edged, irregular, confluent 

 spots reaching to the submedian nervure, beyond this a submarginal 

 irregular line enclosing a marginal row of large greyish-brown lun- 

 ules ; a black spot between the first and second median nervules 

 broadly bordered inwardly with reddish orange ; a short black line 

 on the anal margin near the end of the abdomen. The outer mar- 

 gins of both wings very narrowly black ; cilia greyish white. 



Female. Upperside greyish brown. Primaries with the disk very 

 slightly suffused with light blue scales. Secondaries with a rather 

 large outer-marginal row of slightly darker lunules, bordered in- 

 wardly with greyish and outwardly with a very fine greyish line, 

 the two anal lunules being darkest. Underside as in male, but 

 ground-colour rather browner and less green at base. 



Head, thorax, and abdomen concolorous with wings ; legs white 

 with black spots. Antennae black, annulated with white. A short 

 black tail margined and tipped with white.
