other macrosetae are shifted to the very inner margin. They are shaped like small gracile microsetae . Anal tube appendage (Fig. 83) well defined, with distinct sensory pits. "Upper connective" well developed (Fig. 73). Paramere (Fig. 76) with very short apical part and narrow, small lower part. Connective large, completely fused with the base of penis (Fig. 77). Penis well sclerotized, praeatrium large. Penis stem provided with sclerotized processes (Figs. 77, 78). Gonopore subapical, ventral. Abdomen not darkly pigmented, its dorsal side rather coloured. Abdominal apodemes (Fig. 81) short, narrow, similar to these of Dayus Mahm. The new genus Is related to both Dayus Mahm. and Ifugoa Dwor. et Pawar. Goifa fasciata sp.n. (Figs. 72-83) Ground of face and upper side of head and thorax ivory. A reddish-brown patch at apex of vertex; two lateral patches (seen in Fig. 82), reddish-orange. Centre of pronotum light orange-testaceous, slightly brownish at the midline. Basal triangles orange. Tip of scutellum orange-reddish. Eyes brown. Ocelli testaceous-brownish. In upper part of frontoclypeus a short central longitudinal reddish-orange streak, two similar streaks at lateral frontal sutures; all of them almost joined at the level of ocelli. Sometimes the streaks are joined also at the level of antennae thus bordering two ivory triangles in upper part of frontoclypeus. Two broad reddish-orange streaks on sides of lower part of frontoclypeus. Anteclypeus yellow-orange to reddish-orange. Fore wing semitransparent, colourless in basal 2/3, slightly greyish apically. Costal margin and the margin of wing at hind angle of clavus as clavus as well as a small transverse fascia (marked with dashes in Fig. 74), orange. Anal tube appendage (Fig. 83) terminated on several small tubercles. Penis stem sinuated at base, provided with two rows of small teeth along its ventral wall (Fig. 78). Apex of penis with five processes (Fig. 77), two of them forming loops. Lengtho"2.75 - 2.90, 2.90 - 3.00 mm. Holotype male and paratypes 2 0*0", Hanoi, at light, Oct. 1. Paratypes. Id", 3oç, same locality as the holotype, Oct. 2; 2<S6, Oct. 3; le>, Oct. 30. All collected by T. Pócs in 1963. Paratype Ç, Hanoi, Oct. 4; 1963, coll. A.K. Gogoly. (ISEZ, BM). Empoasca Walsh, 1862 The genus is well represented on both Hemipheres being differentiated to numerous groups of species and subgenera, both very incompletely known for the time being. Group of Empoasca albipennis Empoasca albipennis sp. n. (Figs. 84-96) Ground of body whitish or light testaceous-white. Living specimens probably chalk-white. Fore wing (Fig. 95) hardly semitransparent, whitish, with only 4th apical cell slightly fuscous. Hind wing (Fig. 96) light. Vertex slightly produced in the middle, quite narrow. Pronotum short (Fig. 90). Eyes blackish. Male genital apparatus very characterlstical. Penis stem well sclerotized, tubular, provided with two lateral appendages at apex (Figs. 92, 93). There are two other appendages at base of penis stem on ventral side. Paramere (Fig. 86) twisted and subapical setae visible on its inner side. Teeth at apex of paramere blunt. Anal tube appendage very long (Figs. 85, 88). Pygophore appendage (Figs. 85, 89) bifurcated. Surface of pygophore side covered with sculpture of minute teeth. Rigid microsetae situated at hind margin and about hind lower angle. A few gracile microsetae scattered in hind part of pygophore lobe. Subgenital plate narrow (Figs. 84, 87). Marginal microsetae quite long, "basal group" hardly distinguishable. Gracile microsetae on subgenital plate not numerous, shorter than macrosetae. Connective (Fig. 91) long, sclerotized at margins and at base. Abdominal apodemes (Figs. 94) short but well developed. Abdominal tergites infuscated. Lengthd"2.9 - 3.3 mm.
