basal half of fold blue. Below 
strongly patched with white . . . standingeri. 
5. Warm brown above, spotted like Ly- 
caenesthes (sens, strict.) below. Sec¬ 
ondaries with a marginal row of 
black spots with metallic scales . yemmiferu.

(J. Both wings on the upperside blackish brown; primaries with 
an orange-red oval spot in the fold between veins la and 2, beyond 
the end of the cell, rarely extending very slightly over vein 2 
Underside like N. lusones, Hew., but the colour is not brown but 
blackish, and the orange patch of the primaries does not show through, 
the white margins to the marks are whiter and broader ; with the 
exception of these differences the underside pattern is very closely 
similar. There are certain divergencies, however, in the structure of 
the pattern and in the look of it that render the separation of the 
two comparatively easy. 
5 . Like the male both in the upper- and undersides ; whereas the 
$ of lusones is paler above, and in the secondaries has a pale sub¬ 
terminal line, whilst below it is decidedly paler, with the mark¬ 
ings reduced to a certain extent by the broadness of the white 
lines.

Types ill my collection. 
This species and N. lusones, Hew., are found flying 
together from November to February, and it is possible 
that they may be in many collections mixed together. The 
spot in the primaries of lusones is, however, much larger 
and is always more or less round; in my species it is much 
smaller and always oval. The genitalia also differ in 
several points. 
Genitalia. —Harpago broad, evenly excurved as to its lower edge, 
gradually rising on its upjier edge to near the apex, when it suddenly 
rises again into a high ridge ; front edge erect, at a third very highly 
excavated, fornang a sharp long tooth, the previous part being 
slightly serrated, the lower extremity being produced into a chisel¬ 
like edge. The cingula is of moderate width, well produced back¬ 
wards at its lower edge, gradually tapering to the cheeks of the
