[Read 27th July, 1938.] The species described in the following pages are from various collections and are mostly new. A few previously-known species are redescribed. Besseeioides, n. gen. Intermediate between Besseria Desv. and Hyalomyia Desv. The front is wide in both sexes, the abdomen intermediate in shape between the two genera, broader and less convex than in Besseria and much less flattened than in Hyalomyia. Face very slightly receding, the oral margin very little produced; oral vibrissae weak, situated only a little above the oral margin; front about half as wide as greatest width of one eye; ocellars weak; cheeks one-sixth as wide as eye-height, the oral margin oblique on its anterior third. Antennae situated above the middle of the eyes, reaching almost to the oral margin, the third segment two and one-half times as long as wide, convex apically, the second segment short, arista bare. Parafacials bare; front with a single row of short, convergent bristles on either side. Mesonotum with only bristles laterally and very weak ones posteriorly; scutellum with two pairs of marginal bristles; sternopleurals varying from two to four in a horizontal line. Legs simple. Wings as in Alophora and Besseria. Abdomen oval, moderately convex, without bristles; in both sexes the third sternite is evidently absent, the first is broad, the second triangular and small; in the female the fourth and fifth sternites are large and convex and the piercing ovipositor rests at an angle of about 45° to the horizontal plane of the abdomen. Genotype, Besserioides sexualis, n. sp. Besseeioides sexualis, n. sp. Wings of <$ tinged with brown, especially anteriorly; of $ somewhat paler; abdomen of £ rusty reddish-yellow, of $ shining black. Length 4 to 5-5 mm. <$. Head reddish in ground colour, the occiput and parafrontals black; front, face and cheeks rich yellowish pollinose, the occiput cinereous; frontal vitta much wider than either parafrontal, the frontal bristles not extending above the upper fourth of the front. Occipital cilia extending only to the level of the antennae; pile of the occiput and cheeks whitish or yellowish, the cheeks without bristles. Palpi pale reddish. Antennae pale orange, the third segment darkened above on the apical half; arista brown, thickened on the basal fifth. Thorax black, moderately clothed with brownish cinereous pollen, the pleura with brighter coloured pollen. Hair short and black. Scutellum sometimes mostly reddish. Legs black; pulvilli brown.
