XVII. Uranotaenia caeruleocephala. Theobald 
{Mono. Culicid. II., p. 256, 1901 
I have described the 9 of this species but not the $ , a description of which is here given : — 
$ . Thorax like the iemale, but the metallic patches in front and the lines in front of the wings 
very pale blue in certain lights. The head is brown and deep violet in the middle, with pale blue scales 
on each side ; palpi brown, proboscis brown, swollen at the apex ; antennae banded brown and deep 
brown, densely brown plumed. Abdomen showing a pale apical ventral spot on the fifth segment ; paler 
ventrally than dorsally ; fore ungues unequal, the larger sickle-shaped simple ; mid and hind apparently 
equal and simple, irregularly curved. Wings with brown veins, a line of metallic flat pale blue and 
violet scales at the base of the costa and another at the base of the fifth long vein, posterior cross-vein 
twice its own length distant from the mid cross-vein ; halteres with pale stem and brown knob. 
Length — 3 to 3*5 mm. Habitat — Gambia (Burdk rx 9 ) and (Dutton $ ). Time of capture — 
December. 
Observations — Thesis described from two fairly perfect specimens caught in a marsh behind the 
town on McCarthy Island. I feel certain from the thoracic ornamentation it is the male of U. caeruleocephala 
(mi hi) described from Bonny. The chief difference from the female lies in the head being deep violet in 
the middle, instead of pale blue all over. The markedly bright brown thorax with the metallic white and 
pale blue ornamentation should at once separate it. I had to mount some of the legs of the $ type in 
balsam to make anything of the ungues. In doing so I misplaced them, so am not sure if the anterior 
or mid ungues are unequal. 
XVIII. Corethra ceratopogones. N. sp. 
9 . Thorax pale brown to fawn with darker brown markings ; metanotum pale chestnut-brown ; 
pleurae pale fawn and cinerous ; head brown, proboscis and palpi brown, with numerous rather long brown 
hairs ; antennae banded brown and grey. Abdomen very pale fawn to cinerous, with narrow dark brown 
apical borders to the segments, and dark brown at the sides, only parti}', however, on the last two apical 
segments ; abdomen hairy ; apex dark brown ; lamellae brown. 
Legs multibanded, with brown and frosty grey on the femora and tibiae ; fore femora with six dark 
bands and also the fore tibiae, apex and the basal band of both, pale ; metatarsus and first three tarsi 
banded with dark brown in the middle, apical joint pale, ungues very small, simple, and equal ; mid femora 
with eight dark bands, tibiae with six, the tarsal are broadest, base and apex of both joints pale ; metatarsi 
and tarsi with very broad dark median bands ; ungues small, equal, and simple ; hind femora with eight, 
and hind tibiae with seven dark bands, base and apex of each pale, metatarsus with two median dark bands, 
tarsi with a single median dark band. Ungues small, equal, and simple. Wings densely clothed with long 
brown hair-like scales, with three dusk}' patches on the costa, the median one where the sub-costal joins 
the costa spreading on to it, the apical one spreading on to the first long vein, the basal one rather indistinct, 
the median spread across the wing-field as a faint dusky band ; the third long vein is faintly darker 
than the rest. Wing fringe long and dense ; first submarginal cell considerably longer and narrower than 
the second posterior cell, its base very slightly nearer the base of the wing than that of the second pos- 
terior cell ; its stem about one^fourth the length of the cell, not quite so long as the stem of the second 
posterior cell ; stem of the latter less than half of the cell ; the second long vein carried a long way past 
the marginal cross-vein ; supernumerary and mid cross-veins sloping towards the apex of the wing ; pos- 
terior and mid cross-veins 111 one line. Halteres pale. 
Length — 2 - 5 mm. Habitat — Gambia (Dr. Dutton). Time of capture — December. 
Observations — Described from a single 9 taken by Dr. Dutton on the side of a tub on McCarthy 
Island. It is the only African Corethra known, and can easily be told by the wing ornamentation and
