brown, with a metallic coppery lustre in some lights. Ungues 
equal, small, simple. 
Wings with the veins covered with brown scales; first 
sub-marginal cell a little longer but about the same width as 
the second posterior cell, its base a little nearer the base of the 
wing than that of the second posterior cell ; its stem about 
equal to half the length of the cell, a little shorter than the 
stem of the second posterior cell; posterior cross-vein distant 
rather more than its own length from the mid cross-vein; 
halteres with a pale stem and fuscous knob. 
Length. —4*5 mm. 
£. Head with distinct white border round the eyes; 
proboscis deep brown with paler apex; palpi deep brown, with 
scanty black hair-tufts ; antennae banded brown and grey, with 
the plumes deep silky brown. 
Abdomen with small apical and lateral patches of white, and 
in one specimen the last segment entirely white scaled ; on the 
venter are numerous pale scales. The pos¬ 
terior cross-vein is distant nearly twice its 
own length from the mid cross-vein; when

longitudinal lines may be made out on the 
Wing of cf. (X. 9.) & J 
thorax. 
Ungues of front legs nearly equal, the larger with a distinct 
tooth, the smaller with a small pointed tooth near base; mid 
ungues unequal, but both toothed; hind ones small and simple, 
equal. 
Length. —4’ 5 to 5 mm. 
Habitat. —Sierra Leone (Austen), (8. 1899 and 99. 267). 
Time of capture. —August and September August 15th to 
September 1st. 
Observations. —This species nearly approaches C. dissimilis, 
but the white lateral scales on the apical borders of the segments 
should easily separate it. Although it resembles 0. masculus, it 
can be told from it by the absence of basal banding on the 
abdomen, and by the different structure of the ungues, which 
are very characteristic.
