clasper swollen and with large spines and one large apical curved spine. posterior cell almost uniform in breadth.

First
Although only the male is known, this presents a very marked genus on account 'of the squamose characters of the head, the marked first posterior cell, and the peculiar claspers to the male genitalia. As I had only one specimen to dissect, it was not possible to make out the exact detail of one side of the broadly expanded apex of the claspers.
Bathosomyia abnormalis, nov. sp.
Head with pale creamy scales; palpi and proboscis brown; antennæ flaxen. Thorax brown with pale creamy scales. Abdomen brown with basal creamy bands broadened in the middle. Legs uniformly brown, hind tibiæ with pale apex.
Head deep brown, clothed with loosely applied, flat, pale creamy scales, a few pale narrow-curved ones in the middle near the base; golden chætæ in front, dark ones at the sides; antenna witli broad pale bands and narrow dark ones, plume- hairs flaxen brown; clypeus and proboscis deep brown: palpi deep brown; the two apical segments, of nearly equal length, with scanty brown hairs forming tufts, and a group of long brown hairs at the apex of the ante-penultimate segment; palpi longer than the proboscis. Thorax deep brown, clothed with rather large pale creamy narrow-curved scales and brown chætæ; scutellum ochreous brown with narrow-curved pale creamy scales and four brown border-bristles to the mid lobe; metanotum deep brown; pleuræ brown with patches of pale flat scales. Abdomen brown, clothed with black scales with large basal patches of white scales not quite forming bands, becoming creamy yellow on the sixth and seventh segments, the last all creamy scaled; very long dull golden border-bristles and also lateral ones. Legs brown unbanded, the hind tibiæ with yellow apical spots; fore and mid ungues unequal, uniserrate; hind comparatively large, unequal, simple.
Wings with the first fork-cell longer and narrower than the second, its base nearer the base of the wing, its stem more than half the length of the cell; stem of the second posterior cell as long as the cell; posterior cross-vein not as long as the mid and not quite its own length distant from it; the mid is much longer than the supernumerary.
Clasper of genitalia very marked, broadly expanded apically with several large spines and one large curved broad spine at the apex.
Length: 38 mm.
Habitat: Obuasi.
Time of capture: 7, viii., '07, and 1, x., '07.
Observations: Caught in bush at 10 a.m. Described from two d. The geni- talia are very peculiar, and the general pa1 scaled head and thorax, and the large pale basal abdominal patches, should at once separate it.
Genus: EUMELANOMYIA, nov. gen.
Head clothed almost entirely with rather loose flat scales, a small median basal area of narrow-curved ones and very thin upright forked scales. Thorax and scutellum with rather long narrow-curved scales.
Q-short, of two Palpi of segments, the apical one equal in length to the other; in the male a little shorter than proboscis, apex blunt with a few long chatæ, no hair tuft. Male genitalia very similar to Culiciomyia, but there are two foliate plates on the basal lobe. Fork cells rather short.
This rather obscure genus comes near Culiciomyia, but can be distinguished by the short two segmented palpi, shorter male palpi, and the peculiar bifoliate nature of the genitalia, the clasper, however, strongly resembling the former genus.
brown.
Eumelanomyia inconspicuosa, nov. sp.
Head, thorax, and abdomen deep brown, some grey scales on the head in the middle and sides in front; venter grey scaled. Legs, palpi, and proboscis dark
Head almost black, clothed with flat scales except for a small basal median patch of thin narrow-curved pale golden scales; flat scales dull white in front and the middle and along the eye borders, rest dark; clypeus brown; palpi and proboscis deep brown; antennae brown; palpi bairy.
Thorax black and shiny, with paler scales of a brownish huc, rather long and thin narrow-curved scales; some short pale chætæ in front and sides, longer dark brown ones over the roots of the wings; scutellum black with long thin pale scales

and five dark brown median posterior border-bristles; metanotum shiny black; pleuræ and prothoracic lobes with small dull white flat scales.
Abdomen deep brown, unbanded, with some paler scales laterally and pale border bristles; venter mostly with dull white scales.
Legs uniformly brown, except the coxæ and trochanters, which are rich ochreous, the former with flat dull white scales; ungues small, equal, and simple.
Wings with short fork-cells; the first longer and narrower than the second, its base slightly nearer the base of the wing, its stem less than half the length of the cell, stem of the second posterior cell about two-thirds the length of the cell; posterior cross-vein sloping backwards, about twice its own length distant from the mid; scales dense, straight, and rather thick on the apex of the wing.
Length: 3 mm.
Head similar to 9, but with more prominent, dark, upright, forked scales. Thorax and abdomen as in the 9. Legs with pale venter to femora at base; fore and mid ungues unequal, both large and small are uniserrate; hind small, equal, and simple. Wings with short fork-cells, the first longer and narrower than the second, its base nearer the base of the wing; its stem a little more than half the length of the cell, stem of the second posterior as long as the cell; posterior cross-vein three times its own length distant from the mid.
The male palpi not quite as long as the proboscis, blunt at apex, which bears long chata, no signs of hair-tufts.
Genitalia with the clasper, with short thick spines on its edge near apex and one lateral spine; two foliate plates below, and the lateral process of the basal lobe near its apex, with three long, broad chætæ, four short ones acutely elbowed near the apices.
Length: 3 mm.
Habitat: Obuasi.
Time of capture: 7, 21, viii., 29, ix., 2, x., and 20, xi., '07. Observations: Caught on bush paths and in the bush, 11 a.m.
Described from several ♂'s and 9's. It is a very obscure species, and unless examined microscopically would not be separated from several others described here. The differences, however, are great. The male genitals differ markedly, also the male and female palpi, and necessitate it being placed in a distinct genus.
Genus: PECTINÕPALPUS, nov. gen.
Head clothed with narrow-curved scales, except at the sides and around the eyes in front, and some upright forked scales; antennæ plumose; palpi of male as long as the proboscis, irregular in form, of three segments, basal one swollen at. base, apical twice as long as the penultimate, both with rather long lateral hairs, the long segment with a series of outstanding scales of peculiar form in two groups of different shape. Thorax and scutellum with long narrow-curved scales.
A very distinct told at once by the peculiar & palpi. I have been unable to find the Q.
Pectinopalpus fuscus, nov. sp.
genus,
Uniformly fuscous brown. Fragile Palpi very irregular and twisted in form. Head black with pale smoky grey narrow-curved scales over most of the area, dusky grey flat lateral scales and almost white ones around the eyes. Palpi and proboscis deep brown; antennæ brown with pale bands and flaxen plume-hairs; the papi have eight pale outstanding scales on long stalks on one side of the apical area of the long segment, and then eight dark long outstanding scales below of different form.
Thorax brown with dull brown and dull, pale golden, rather long, narrow-curved scales and deep brown chætæ; scutellum paler brown, with narrow-curved pale scales and six brown bristles to the mid lobe; metanotum pale brown.
Abdomen uniformly fuscous brown.
Legs uniformly brown; femora and coxe paler, the former especially below; fore and mid ungues unequal and uniserrate. hind equal and simple.
Wings with rather broad scales on the apex, with rounded tips; first fork-cell longer and narrower than the second, its base about level with that of the latter, its
