dorsal. Dorsal plate with a tuft of quite long setae just before the base of the apical process. Genitalia of male (Pl. 10, Fig. C) with the proctiger stout, its posterior margin strongly convex and fringed with hairs, the claspers rather short and broad, diagonally truncate at the apex and with a narrow, sclerotic apical rim. Powellia subacuta, sp. n. (Pl. 10, Figs. D, F.) Material Examined.—Holotype, a female, and allotype, Wilton's Bush; two paratype females, Wellington Botanical Gardens (J. G. Myers); one paratype female, Day's Bay, Wellington; one paratype female, York Bay, Wellington (I. H. Myers). Colour.—Notes not available. Structure.—Very close to P. acuta. Wings, however, beset throughout with punctations except for narrow areas paralleling the veins. Genitalia of female (Pl. 10, Fig. D) with the prolongation of both dorsal and ventral plates shorter and less acute. Genitalia of the male (Pl. 10, Fig. F) with the proctiger strongly angular and the claspers slender, tapering slightly in their apical fourth to the truncate apex. Powellia decurvata, sp. n. (Pl. 10, Figs. H, I.) Specimens Examined.—Holotype, a male, and a paratype male, York Bay, Wellington (J. G. Myers); allotype, Mount Maunganui, Wellington, 2300 feet (J. G. Myers); males and females, Bull Mound, Tararua Mts., 3300 feet; female, Arthur's Pass (J. G. Myers); male, Auckland (J. G. Myers). Colour.—Of a general light brown colour with darker markings on head and thorax; wings very pale brown. Structure.—Antennae about one and a-half times as long as the width of the head. Genae fully as long as the vertex and noticeably slender. Wings slightly rounded at apex, the radial sector almost attaining apex and paralleling costal margin, membrane punctate throughout, more strongly so at base, without bare areas along veins. Hind wings with veins formed by a slight pigmentation of the membrane and a concentration of the small points. Hind tibiae with the basal spurs rather weakly developed. Genitalia of female (Pl. 10, Fig. H) forming two-thirds of the length of the expanded abdomen, the dorsal plate considerably exceeding the ventral, tapering regularly to the apex and strongly curved downward, the two plates gaping widely. Genitalia of male (Pl. 10, Fig. I) with the proctiger elongate and somewhat flask shaped, the posterior border beset with a fringe of long setae; claspers quite long, moderately slender, parallel-sided, with the apex rounded and without hooks or sclerotic processes, the inner face with numerous small setae near apex.
