of scales on the occiput, and a small black patch on each side, 
the spaces between creamy-grey, numerous small upright forked 
scales behind ; proboscis very short, brown, with a broad creamy 
median band; palpi short, brown, grey at apex; antennae 
brown, basal joint paler. 
Thorax bright chestnut-brown, covered with small narrow 
curved scales, the majority bronzy, but with two large more or 
less distinct rings of silvery grey ones which meet in the middle 
line, and with numerous broader silvery scales before the 
scutellum; scutellum brown, with small Hat scales of a grey 
tint, with five median border-bristles ; metanotum pale ochraceous- 
brown ; pleurae brown, with flat grey scales in patches. 
Abdomen brown, with brown-ochraceous and white scales, 
the white forming apical lateral spots, the ochraceous, median 
and apical lines, and forming most of the apical segments. 
Legs brown, banded with creamy white on all the joints, the 
pale bands on the tarsi being apical, last tarsal joint unbanded. 
Wings spotted like an Anopheles; scales short and rather 
broad like G. atratus all over the wing, base of the wing white; 
three large black patches along the costa, the apical one having 
a large and a small patch beneath it on the first long vein, the 
median one having one of similar size beneath it, the basal one 
also having one of similar size, between the median and basal is 
a small dark spot on the first long vein; veins mostly brown 
scaled with a few small spots of pale scales; fringe brown 
with pale scaled areas where the veins join the border; fork- 
cells rather short; first submarginal cell a little longer and 
narrower than the second posterior cell, its stem about half the. 
length of the cell; posterior cross-vein a long way from the mid 
cross-vein, at least four times its own length distant. 
Halteres with pale stem and fuscous knob. 
Length .—4 mm. 
Habitat .—New Guinea. 
Observations .—Described from a somewhat damaged specimen 
sent me by Dr. Donitz, who has described the 9 from New 
Guinea. The $ is unknown. It is a most marked and 
beautiful species, and will probably have to be included in a 
new genus. The spotted wings look like some Anopheles, and 
the many banded legs like a Panoplites. Scales on the wings 
resemble C. atratus, and the head ornamentation is peculiar.
