short, its three parts of almost equal length, no distinct praeapical lobe, a few sensory pits along outer margin of its caudal part (Fig. 313). Connective (Fig. 319) lamellate, with small central lobe. Penis stem tubular, with appendages, large praeatrium, laterally compressed apodeme, subterminal, ventral gonopore (Figs 320, 321). Basal abdominal apodemes of male very large, heavily sclerotized (Figs 317, 322). Remarks. The new genus shows unique characters of subgenital plate and dorsal articulation of penis, exceptional is its minute, heavily sclerotized upper pygofer appendage. <• Chagria sikkimensis (Datta et Ghosh, 1973) comb. n. (Figs 310-326) Typhlocyba sikkimensis Datta et Ghosh, 1973 p. 418 There is sexual dimorphism in colouration. In male anteclypeus, lorae, ventral and lateral parts of frontoclypeus brownish; remaining parts ochre-yellowish centrally (darker ventrad); genae whitish. In female anteclypeus and frontoclypeus dark brown; lorae, inner parts of genae and antennae sordid brownish and outer parts of genae sordid whitish. Transition vertex to face sordid whitish, with two large blackish patches, area between the patches ochreous. Vertex of female slightly more produced anteriorly. In both sexes transverse brownish infuscation on vertex basally, larger in male. Vertex and pronotum brown, anterior margin of pronotum lighter in several areas.
