_ This beautiful and very distinct species is most nearly allied 
to JT. Terpander of Hewitson (Proc. Zool. Soc. 1862, p. 90), 
which I consider to be the msect figured inadvertently in the 
‘Genera of Diurnal Lepidoptera’ (pl. 21. fig. 3) as the Cla- 
rissa of Boisduval, the latter being a much larger species, with 
more strongly falcated fore wings. My species only differs from 
Terpander, on the underside, in the narrower and darker yellow 
discal band and smaller white spots of the hind wings. 
Genus Nepris, Fabricius.

Alee supra nigerrimee : anticee stria triangulari discoidali, macula con- 
tigua cuneata, maculis tribus subapicalibus ineequalibus, tribus sub- 
analibus oblique positis punctisque octo submarginalibus niveis ; 
punctis octo marginalibus striaque valde indistincta irregulari dis- 
cali subcinereis : posticee fascia subbasali et altera septemmaculari 
discali niveis ; stria submarginali maculari subcinerea, fascia media 
fuscescente indistincta : corpus nigrum, virescens; antennis nigris, 
flavo acuminatis. 
Alee subtus pallidiores, striis discali anticarum et media posticarum 
violaceis, stria submarginali canescente; stria marginali cinerea ; 
costa basali posticarum nivea; aliter velut supra: corpus ceeruleo- 
albidum ; pedibus ochreis; antennis ferrugineis.
