to the first; hind equal and simple. Claspers of the genitalia rather broad and deep brown. Antennæ densely plumose with brown plume hairs.
Length: 5 mm.
Habitat: Accra.
Time of capture: 8, 14, 19, vi., '08.
Observations: Described from two O's and one ♂ caught in latrines.
The species comes very near C. taeniorhynchus, but can at once be told by the thoracic adornment, less conspicuous banded abdomen and legs, and non-serrate ungues in the 9:
Culicelsa accraensis, nov. sp.; var. fuscus, n.v.
This exactly resembles the type, but the thorax is clothed entirely with bronzy scales, except the scutellum, and all the upright forked scales are dark.
Locality and time of appearance same as the type, but a few days earlier, according to the dates on the specimens.
From the markedly bronzy scaled thorax, thus differing from the type, I should place this as a distinct species but for the fact that one specimen shows many pale scales on the thorax and is thus intermediate, but nevertheless has all the forked cephalic scales black.
Genus: PROTOMELANOCONION, nov. sp.
Head and thorax clothed with narrow-curved scales, the former with dense upright forked scales; palpi of 9 very short, of male three-fourths the length of the proboscis; antennæ venticillate in 9; densely plumose in d. Lateral vein scales long and thin, much as in Neomelanoconion.
The male palpi are composed of three segments, the apical one small and pine- apple shaped, the penultimate about six times its length, curved and with a row of short spines on one side at the apex.
This genus differs only in that the males have shorter palpi than the proboscis.
Protomelanoconion fusca, nov. sp.
Head and thorax fuscous brown, pleuræ ochreous; head pale around the eyes; abdomen black with small basal lateral pale spots; pale ventrally at the apex. Legs black, pale on the venter of femora at base. Palpi and proboscis deep brown.
Q. Head black clothed with fuscous narrow-curved scales, grey around the edges of the eyes; numerous black upright forked scales and long black forwardly project- ing chætæ; clypeus brown; palpi very short, black scaled, with a few black chætæ; proboscis black; antennæ deep blackish brown.
Thorax black with dusky bronze narrow-curved scales and jet black chætæ; scutellum brown with fuscous narrow-curved scales and four black border-bristles to the mid lobe; metanotum black; pleuræ ochreous with some paler flat scales.
Abdomen shiny black clothed with fuscous black scales, small basal creamy white lateral spots and dusky and grey border-bristles; venter white scaled, the scales outstanding on the apical segments.
Legs uniformly black with dull ochreous reflections, venter of femora pale, apex of hind tibiæ yellow beneath; chætæ black, ungues equal and simple.
Wings with the first fork-cell longer and narrower than the second, its base nearer the base of the wing its stem less than one-third the length of the cell; stem of the second fork-cell nearly two-thirds the length of the cell; posterior cross-vein about twice its own length distant from the mid. Halteres with ochreous stem and fuscous knob.
Length: 25 to 3 mm.
d. Head, thorax, and abdomen as in the 9. about three-fourths the length of the proboscis, slightly bent in near the tip, with Proboscis black, palpi black apical spines and a small lateral tuft on one side near the apex; antennæ densely plumose, plume hairs deep brown. Ungues also simple, the fore and mid unequal."
Length: 25 mm.
Habitat: Obuasi, Accra.
Time of capture: 14, 17, 20 and 21, vi., '08.
Observations: Described from two 9's and two ♂'s taken in latrines at both localities. It is a small obscure species and can only be told by careful examination in the . The male palpi are very marked.

Genus: URANOTÆNIA, Arribalzaza.
(Dipt. Argentina, p. 63, 1899.) Uranotænia bilineata, nov. sp.
Head dark in the middle, white around the eyes. Thorax bright brown, a thin pale almost white line in front of the roots of the wings, a longer parallel one below extending from the head to the wings.
Abdomen deep brown, unbanded, paler below. Legs brown, the hind pair with apical and basal creamy banding, last two tarsi all creamy white.
Head clothed with flat black scales in the middle, white ones around the eyes and blue ones at the sides, upright forked scales black; chætæ black; palpi and proboscis deep brown, the latter hairy at the apex; antennæ deep brown, basal segment bright testaceous; eyes metallic violet, coppery, and silvery. white scales projects between the eyes.
A tuft of
Thorax rich brown in the middle, darker at the sides, with narrow-curved bronzy scales and black chætæ; a thin line of broader white scales in front of the roots of the wings and another of flat white scales extending from the white scale prothoracic lobes to the end of the mesonotum, parallel with the shorter one above; scutellum bright brown with small flat dusky scales and four brown median posterior border- bristles; metanotum black.
Abdomen dusky black, unbanded, posterior border-bristles pale golden; venter creamy scaled and some pale scales at the apex above; lateral hairs golden.
Legs, fore and mid pairs ochreous brown, paler feet, very faint traces of pale banding; hind legs with the base and apex of the metatarsi, first and second tarsal segments broadly yellow, last two segments pale yellow, almost creamy; femora pale at the base and below.
Wings with the basal half of the first long vein creamy scaled, rest brown; first fork-cell slightly shorter and narrower than the second fork-cell, its base a very little nearer the apex of the wing, its stem about two and a half times the length of the cell; stem of the second posterior about one and a half times the length of the cell; posterior cross-vein a little more than its own length distant from the mid cross-vein; halteres with dusky ochreous stem and fuscous knob.
