each side l)y a deep creamy patcli, that on the outside being tlie 
larger of the two. Secondaries with a spot closing the cell ; post- 
median stripe very irregular, the spots small ; outside this a deep 
yellowish-cream line almost angled at vein 5, a terminal row of 
small spots decreasing towards the apex and edged internally by a 
fine whitish line. Underside white with the usual markings of this 
section of the group — the distinguishing feature being the exces¬ 
sively oblique costal part of the postmedian stripe of the primaries.

Type in the British Museum. 
The species is quite different from others of this genus ; 
it is superficially nearest to Neurypexina lyzanius, Hew., 
but the neuration is that of a true Lycaenesthes. 
Genitalia . — Harpago subovate, with the fore edge developing two 
teeth, the upper one formed by a slight excision of the front line 
and not extruded, the lower one at the apex longish. Cingula well 
developed with a deep curve at the back of the girdle, making the 
tegumen very narrow ; it (the tegumen) is deejjly excised with the 
cheeks tapering off narrowly into an acute angle at their lower 
extremity. Falces much exposed owing to the narrowness of the 
cheeks of the tegumen, moderately strong and well curved at about 
a third from their sockets. Furca short, almost erect with short 
narrow arms. Penis sheath small, widest beyond the middle, i. e. 
near the top, where it tapers down very rapidly to the oblique 
extremity. Cheeks of tegumen with an abundance of long hairs, 
harpagines with a more scanty supply. 
This species is with some difficulty separable from 
many specimens of Neurypexina lyzanius, Hew., if the 
colour and pattern only are considered ; the genitalia, how¬ 
ever are decidedly different, so that with the neuration 
differing also, we are abundantly justified in placing Hewit- 
son’s species in another genus.

(t. Botli wings uniform dark brown. Primaries markless. 
Secondaries with three marginal spots edged all round, except on 
the termen, with orange yellow, one between veins 3 and 4, one 
between 2 and 3, and a twin spot at the angle. Underside ; both 
wings pale greyish, with the pattern marked out by white lines not 
darker than the ground-colour except in one or two places which
