nal joint 2 with a rather long hair above. Eyes large, cheeks only as wide as 1/3 width of antennái joint 3. Vibrissae setiform, thin, shorter than third antenna! joint. Peristomal and postocular hairs weak. Genae, palpi, and proboscis yellow, latter one comparatively large. Frons grey, orbitals with a lighter yellowish tinge anteri­orly, cheeks greyish yellow, antenna grey, second joint darker than the others. Thorax slightly wader than head, dorsally grey, with one acrostichal and 2 dorso­central, brownish-grey, dark stripes, separated by a distance equalling about width of one stripe. Two rows each of acrostichal, dorsocentral, and intraalar microchaeta present. Humeral bristle absent, but one pair each of anterior and posterior no­topleurals, anterior postalars, and 1 moderately long dorsocentral present. Scutel­Figs. 1-2. Anarista endroedyi gen. nov., sp. n. 1: antenna, 2: wing. lu m verj- short, apical scutellar pair very long and thick, lateral pair thin, hardly longer than one-fourth length of apicals. Scutellum grey like thorax, scutellar bases surrounded by one darker spot each. Shoulders and notopleura somewhat lighter than ground colour, upper- part of meso- and pteropleura slightly darker in an obscure stripe than basic colour. Mesopleura entirely glabrous, sternopleura with 2 minute but comparatively long bristles. Lower part of sternopleura and coxae with longer, slightly reclinate, setiform hairs. Legs preponderantly yellow, darker only towards upper end of coxae, without characteristic bristles, but elon­gately hairy, hairs yellow. A dark stripe each below lower fourth of middle and hind femora, and on upper fourth of middle and hind tibia. Wing relatively wide (Fig. 2), alar length of holotype 0.97 mm, breadth 0.43 mm. Costal extending to median, nowhere broken or interrupted. Basal part of subcostal and humeral equally w r ell discernible, subcostal apically not reaching costal but disappearing in subcostal cell. Vein r 2H _ 3 very short and arcuate, distinctly terminating in r v Veins r 4+5 and m distally considerably convergent, posterior cross-vein as strong as anterior one, dis­tance between them only one and a half times as great as length of posterior cross-vein . Cubital short, extending to less than two-third distance between posterior cross­vein and its extrapolation to wing margin, apically slightly recurving. Basal cross­vein, anal cell and anal vein absent. Alar margin elongately ciliate. especially be­tween alar apex and alular region. Alula practically reduced to a linear form, bear­ing some cilia anteriorly, inner base of wing wholly glabrous. Head of haltères large, yellow, its stalk slightly greyish, basally dark grey. Abdomen yellow, compar­atively short, weakly chitinized; tergites narrow, with sporadically appearing, short, grey hairs. Genital organs minute. Body length: 0.9-1.0 mm.
