black and white hairs, abdomen sullied white. $ . Upperside :

 white with iridescent blue scales ; a transverse dark discocellular 

 spot but no anticiliary dark lines. Hind wing : dusky brown, 

 slightly .bluish between the veins on basal half of wing. Under- 

 side : pale ochraceous white, markings similar to those in the <$ , 

 but as they are dark ochraceous they show up more distinctly. 

 Antennae, head, thorax and abdomen dark brown ; beneath : the 

 palpi and thorax white, abdomen pale ochraceous.

A variable insect so far as the shade of the ground-colour is 

 concerned, but like N. hampsoni the basal markings on the under- 

 side of the fore wing stop short at the median vein.

c? . Upperside : pale brown flushed with shining purple. Fore 

 and hind wings : the purple gloss not extended to the dorsum of 

 the hind wing nor to the costal and terminal margins of either 

 wing, all of which are narrowly edged with the pale brown of the 

 ground-colour, beyond which along the termen of both wings are 

 slender anticiliary lines. Cilia pale, their bases brown. Underside : 

 dull brown. Fore wing : two short slightly crenulate lines trans- 

 versely across the middle of cell and two similar lines along the 

 discocellulars, followed by a transverse, irregular, catenulated, 

 discal band slightly darker than the ground-colour and margined 

 inwardly and outwardly by slender white lines ; terminal 

 markings : a subterminal line of spots similarly slightly darker 

 than the ground-colour and margined with white lines; basal 

 posterior half of wing below cell immaculate ; finally, an anti- 

 ciliary dark brown line. Hind wing : the following transverse, 

 somewhat crenulate, slender white lines, between each pair of 

 which the ground-colour is slightly darker : an oblique pair at 

 base, a pair along the discocellulars and a very irregular sinuous 

 discal pair, the last dislocated at vein 6, the posterior portion 

 curved and shifted outwards ; these are followed by a subterminal 

 inner and outer series of arrow-shaped lunules and an anticiliary 

 dark line, this last with a very slender inner whitish edging ; 

 finally, a minute black spot near the termen in interspace 1 a, 

 another similar spot in interspace 1 and a very much larger round 

 black spot in interspace 2 ; all these spots touched with white on 

 the inner side. Antennae black, the shafts speckled with white ; 

 head, thorax and abdomen brown slightly purplish on the thorax 

 and abdomen ; beneath : palpi, thorax and abdomen dusky 

 brownish-white.
