Dr. T. A. Chapman on two new species of Lycaenopsis, 185 
arched on its basal side—a bright white line round eyes; palpi black 
with long white scaling beneath; antennae black with extremely 
narrow white rings at joints. Exp. al. 24 mm.—very small for a 
Lycaenopsis, and with a rather acute apex, like matanga. 
The appendages have large rounded dorsal pieces and unarmed 
clasps, not altogether unlike those of ceya or plauta, a form appa- 
rently usual with the more southern species of the group and not 
dissimilar to those of Megisba mabaya, which is certainly very close 
to Lycaenopsis. 
The clasps are long, rounded at ends, and constricted in middle, 
almost dumb-bell-shaped, again suggestive rather of M. malaya than 
the more typical Lycaenopsids. 
The aedoeagus is rather shorter and stouter than that of L. 
matanga, but otherwise of similar structure. 
Two specimens ¢ 3, Sarawak Museum, labelled Matang 
Road, 7, 3, 10 (type), and Matang Road, December 29th, 
1909. 
I understand that one of these specimens will be placed 
in B.M., South Kensington. 
Lycaenopsis matanga, n.sp. (Plate XX VIIL, figs. 1,2,3,4.) 
Upper surface dark (black-brown) with a darker line at end of 
cell, in one specimen, hardly in the other; on the upperwing is an 
area of blue, rather violet in one specimen, greenish in the other, 
from the cell to inner margin, extending upwards beyond the cell, 
leaving a black margin 4 mm. wide at tornus, 3 mm. wide at vein 
4. In one specimen it is a little more restricted, in the other it 
has a faint extension over the lower margin of the cell. In the hind- 
wing there is a slight central tint in one specimen, in the other the 
blue extends to 7 mm. from base and is 4 mm. across. 
Underside white, fringes with outer half paler, with a smoky tint 
along costa and hindmargin of forewing, in one specimen involving 
most of the wing. Underside has little marking under forewing 
(not altogether from poor condition) in one specimen, in the other is 
a discal line (dark with white margin) and the post-discal series of 
spots (cinereous with white borders) consists of 6 spots, the first four 
in a slightly curved line, the third askew, as in puspa, the fifth is set 
in abruptly from the 4th and is in a straight line with the sixth, 
both being somewhat linear, pointing to costal end of first spot. 
Within the dark fringe is a white line, then a dark one, a paler spot 
(in each space) and an arched spot; the dark lines (or spots) are 
weakly marked, and outline the marginal eyespots. The hindwing 
has the costal and discal spots of the usual transverse basal set, the
