Trans. N. Zealand Institute, vol. xxvii, p. 70, pi. vii, figs. 9-19, 1894. Froggatt, Agrir, Gazette , vol. ix, p. 495, 1898. This species is found upon the branchlets of various species of sheoaks {Casuarina). growing at Thornleigh and Manly, New South Fig. HI— Frenchia semiccculta, Kaskell. In this species the male coccids cause distinctive galls, or swollen corru- gations on the branchlets, congregating in clusters of half a dozen or more, forming a chamber with a terminal orifice above, about one-twelfth of an inch in height, between two swollen, thickened lips, swelling out of the bark. The female hides under the bark, forming a circular tubular opening above, through which she projects her tail. Adult female yellowish, tinged with red to dull red, about one-tenth of an inch in diameter; before gestation the body is subcircular and not half the size, ventral surface convex, rostrum iipon a boss in the centre, very small; legs and antennae wanting. From the centre of the dorsal surface springs the tail, which is bluntly rounded at the tip. After treatment in potash a hairless anal ring and two minute spines are seen near the tip. 117.
