XIII. Two new species of Lycaenopsis from Borneo 
(Sarawak), By Dr. T. A. CHAPMAN.

PLATE. noon alae 
THE two species here described appear to be new, as I 
find no descriptions that will apply to them. The photo- 
graphs of the insects and those of the male appendages 
will make it easy to recognise the insect with none of the 
doubt that pertains to some descriptions in this genus. I 
append descriptions rather out of deference to custom 
than as of necessity. 
The butterflies were accompanied by a specimen labelled 
nigerrimus, R.S., unfortunately without an abdomen, and 
a female example of apparently another new species. As 
it was of course impossible to examine the male append- 
ages of these species, I say nothing further about them. 
Lycaenopsis moultoni, n.sp. (Plate XXVIII figs. 5, 6, 7.) 
Rather brilliant bochus-like blue with a broad black border along 
costa and round hind margins, 3 mm. wide from apex and 1:2 mm. 
round margin—dead black in one specimen, in the other each space 
round hindwing is faintly paler with a dark spot or line in it centrally ; 
no discal line or other mark; fringe dark at base, whitish at edge. 
Beneath, greyish white, spots faintly darker, except two costal spots 
and three towards anal angle of hindwing, black, all margined or 
ringed paler. Discal lines in both wings. Postdiscal row of forewing 
forms a nearly continuous line, except a break inwards of fourth 
spot from third on vein 4. Hindwing, basal row of spots present, 
one costal and one in cell; postdiscal row, costal, large black, 2nd 
below it or rather basal to it ; 3rd and 4th much further out, 5th a 
little basal to these, but nearly in line; 6th black, more basal, and 
8th nearly as much so, 7th rather far out, these three large and 
conspicuous. 
The margin presents fringe brownish with white line at base, 
then a black line round wing margin, a little way in a not very 
dark line is arched inwards over each space, leaving a pale patch 
with a central nearly black mark straight on its outer margin,
