The apical portion contracted and rounded, with the cleft on the summit; the apical orifice forms a slit at the bottom of the depression. Adult female pale yellow, broad to the base, flattened on the ventral surface, with the abdominal segments much broader than usual, rounded at the apex. Dorsal sm-face thickly clothed with fine white hairs, extending beyond the segmental divisions, and forming marginal tufts; a few scattered reddish spines on the last thoracic segment, and more scattered spines on the first two abdominal segments; third to sixth abdominal segments fringed across with larger, closer spines and bristles; at the base is a distinct anal ring. The anal appendages widely apart at the base, standing out like long spiral horns, roughened, with tubercles bearing fine hairs, turning outward at the tips, which are cleft and furnished with three long bristles. Length, f inch, and much broader in proportion than the turbinate forms. Male galls thickly scattered over the leaves; short, tubular, roughened, and expanded at the apex. Height, J inch. 139.

This unique specimen came from Wingham, Manning River, New South Wales, where it was growing upon the leaf of an undetermined species of eucalypt. Female gall very slender, cylindri- cal, slightly roughened on the sur- face, swelling out at the apex into an oval form twice the width of the base; the apex rounded, apical orifice small, circular. Height, | inch; \ inch in diameter at the widest place. Male gall envelope with a short stalk springing f
