upwards on to the dorsum on the last three segments: border-bristles dusky; venter with yellow basal and black apical bands.

Legs deep brown, unbanded, pale at the base and ventrally; the hind tibiæ with a broad yellow, apical hand and some ochreous scales in the middle and ochreous venter; ungues all equal and uniserrate.

/

Wings brown-scaled, with the basal portion of the first longitudinal yellow- scaled, and some yellow scales on the base of the fifth; first fork-cell longer and narrower than the second fork-cell, their bases about level; stem of the former about half the length of the cell, stem of the latter about two-thirds the length of the cell; posterior cross-vein about one and a half times its own length distant from the mid cross-vein.

Halteres with testaceous stem and fuscous knob.

Length: 35 to 45 mm.

Habitat: Obuasi.

Time of capture: 2, ix., '07; 7 and 11, viii., '07; 8, xii.. '07; 1, 2, 29, x., '07; 6. xii., '07; 12, vii., '07.

(Dr. Graham gives June, July, August, October, November, and December as dates of occurrence.)

Observations. A long series caught in bush at 10 a.m., 3 p.m., 11 a.m., 6 p.m. They show some variation, one having the golden scales very dense over the thorax and another show's a greater quantity of pale scales in the middle of the hind tibiæ; in another the proboscis bands not very distinct. It much resembles B. luteolateralis, but is smaller in general form and the marked proboscis band at once separates it. The pale scaled area at the base of the wings is also characteristic.

Banksinella puntocostalis, nov. sp.

Head deep golden in the middle and at the sides, dark between; proboscis black with a median yellow band. Thorax black with bronzy scales, deep bright golden all around the front and sides. Abdomen unbanded, with basal creamy lateral spots. Femora pale creamy yellow with black apex; hind tibiæ golden with black base and a band near apex; all the tibia pale golden, ochreous ventrally; metatarsi and tarsi black. Wings with yellow and brown scales, the costa mainly dark, except at the base, with two prominent creamy yellow spots near the apex.

9. Head dark with a median area of bright golden narrow-curved scales and yellow, upright forked scales, flat, black-scaled area at the sides, and then a flat, creamy-scaled area, and pale scales around eye borders; palpi black; proboscis black with a prominent median golden yellow band; antennæ black, basal segment bright ochraceous and, to some extent, the base of the second segment.

Thorax black with narrow-curved bronzy scales in the middle with a few scattered golden ones, dense bright golden scales around the front and sides forming a broad border to the dark area; many golden scales behind; scutellum with all golden narrow-curved scales; metanotum black.

Abdomen black scaled, cach segment with basal yellow lateral spots, last segment with many pale scales dorsally; venter mainly pale creamy yellow.

•

Legs, fore pair black except the apex of the tibiæ and venter of the femora, the tibiæ ochreous below; hind legs very similar, but the femora paler basally; hind pair with the femora all pale yellow except the apex, which is black, except just at the tip, where it is pale; tibiæ yellow, a broad black band at the base and a narrow one near the apex; ungues equal and uniserrate.

Wings with the black costa with a line of yellow scales along its basal half, then all black, then a yellow patch at the junction of the subcostal and another at the junction of the first long vein: subcostal dark except where it joins the costa; first long vein yellow at its basal half, then dark, then yellow again under the two costal spots; second long vein dark, with yellow lateral scales before and at the fork, and at the apices of the branches, especially the outer branch under the apical costal spot; third with a pale median spot; fourth with some yellow lateral scales before the fork; the basal area and up to just past the fork of the fifth yellow; first fork-cell longer and a little narrower than the second, its base slightly nearer the base of the wing, its stem about one-third the length of the cell; stem of the second posterior cell more than half the length of the cell; posterior cross-vein about twice its own length distant from the mid.

Length: 45 mm.

Habitat: Obuasi.

Time of capture: 7, viii., '07.

Observations: Described from one 2 caught in the bush. This is a very beautiful insect, which differs in ornamentation so much from the typical Banksinella luteolateralis that I have separated it as a distinct species. The markedly adorned wings are very pronounced, and give it an almost Anopheline appearance.

Genus: CULEX, Linnæus.

Culex pseudoannulioris, nov. sp.

Head dull ochreous with a dark patch on cach side; proboscis black with a median creamy band. Thorax brown, somewhat ornamented with brown and dull ochreous scales; abdomen unbanded, with indistinct, pale creamy, lateral, basal areas; venter with basal creamy bands to the segments. Legs brown, with narrow basal dull yellow bands.

9 Head deep brown with narrow-curved pale golden scales and flat pale lateral ones, upright forked scales deep brown; chata brown except between the eyes; where they are golden; clypeus brown; palpi black with black chate; proboscis black with a pale median band; antennæ very dark brown.

Thorax deep brown with narrow-curved, dull, pale golden and brown scales, paler in front of the roots of the wings, the chate brown; scutellum brown with narrow-curved, pale golden scales and ten brown border-bristles to the mid lobe; metanotum deep brown; pleura brown with patches of pale creamy flat scales.

Abdomen unbanded, deep blackish-brown with lateral creamy scales, which to some extent form apical spots above; venter with basal creamy bands.

Legs deep brown, apex of femora with a few yellow scales, hase of metatarsi and first three tarsi with a narrow yellow band, a few pale scales spreading onto the apices of the segments; apex of hind tibiæ with a number of outstanding small golden chatæ, some larger black ones at the apex, and a few pale scales; ungues equal and simple.

Wings with the fork-cells rather long and narrow, the first considerably longer and a little narrower than the second, their bases level; stem of the first about one- third the length of the cell; stem of the second less than half the length of the cell; posterior cross-vein longer than the mid, about its own length distant from it.

Length: 75 to 8 mm. Habitat: Obuasi.
