SOUTH-AFKICAN BUTTERFLIES. 
in a longitudinal line with that just beyond extremity of cell ; large 
spot on disc between third and first median nervules about the same 
size as costal bar, but less elongate and more rounded ; inner-marginal 
marking rather small, acuminate superiorly ; five almost parallel, thin, 
submarginal white streaks, of which the innermost is indistinct and 
more widely separated from the rest, more irregular, and the outermost 
also indistinct. Hind-iving : central band broad, even, extending to 
inner-marginal edge but not to costa, being abruptly rounded off just 
below the first subcostal nervule ; five submarginal streaks much as 
in fore-wing, but more distinct, the innermost less irregular and more 
remote from the second. Under side. — Ground-colour much paler, 
almost grey ; markings corresponding with those of upper side, but 
submarginal streaks broader and more conspicuous. Fore-iving : 
cellular longitudinal bar not, or but very indistinctly, transversely 
divided. Hincl-iving : basal portion with three curved transverse white 
stripes (much as in N, Agatha^ Cramer, but not nearly so conspicuous), 
of which the first is on costal edge, and the third near central band, 
and less distinct than the others. 
This butterfly is allied to N. Melicerta, Drury (nec Cramer), and to 
i\r. Mar])cssa, Hopff., but is considerably smaller than those species. 
It agrees with the former insect in possessing the longitudinal white 
bar ^ in the discoidal cell of the fore-wings (which character at once 
separates it from Marpcssa), but differs markedly (i) in the shorty com- 
'pad^ undivided costal har of the fore-iuings ; (2) in the hroad, even, 
superiorly -rounded hand of the hind-ioings ; and (3) in having four 
(instead of three) parallel hind-marginal white lines. Other characters 
separating it from Marpcssa are the small size and acuminated form of 
the inner-marginal white marking of the fore- wings, and the entirely 
different colouring and pattern of the under side. 
Mr. W. D. Gooch, after whom I have named this species, met with four 
specimens in the neighbourhood of his plantation (Spring Vale) on the coast of 
^^atal. No other examples came under my notice until Colonel Bowker sent 
one taken near D'Urban in December 1879, and again, in June 1881, for- 
warded four others captured in the same locality. Nothing special in the 
habits of the butterfly has been noted by either observer ; and it is not 
unlikely that N. Goochii may often be passed over in mistake for N. Marpessa.

In four of Colonel Bowker's specimens the inner portion of this bar is almost obsolete.
