Text Appearing Before Image:
insect at this stage is reddish brown, as is also the surface of the leaf onwhich it feeds, the effect of this double glassy fringe of silver is of greatbeauty. The tubes of the fringe are not quite straight. Each pair springsfrom one of the figure-of-8 orifices, and the tips slightly diverge. The adult female is covered over with a smooth, hard, semi-transparenttest, convex above, flat beneath, and on the underside this test is also almostclosed, leaving only an orifice for the rostral setae, so that the insect is reallyenclosed : but at the extreme end of the abdomen the upper and lowerportions of the test are slightly parted, leaving an opening. The test (fig.35) is oval, but tapers towards the anal extremity, and in all the specimenswhich I have seen this anal end was turned towards the tip of the leaf. Ishould imagine that the reason for this is to facilitate the work of the male(though I have not as yet found any male insects). The leaves of Leuco- TRANS. N.ZJNS(IT!JTE,V0LMP1.M.

WMMasJcdlM. COCC/D/E. Maskell.—On New Zealand Coccidse. 225 pogon fraseri, on which Planchonia epacridis is found, are often pretty closelyimbricated, and there would be considerable difficulty for the male toimpregnate the female if the abdomen of the latter were turned towards thestem of the plant. By turning the abdomen towards the tip of the leaf themale may with ease reach the female through the opening, just mentioned,between the portions of the test. Accordingly, in several scores of speci-mens which I have examined, the abdominal extremity of the test is directedto the tip of the leaf. The test, in all cases which I have seen, is of two colours: one half, atthe cephalic end, is dark green, the other, or abdominal half, is bright yellow.All round the edge runs, as in the second stage, a long silver fringe indouble row, one row over the other. The contrast of these colours with thedark reddish-brown of the leaf is extremely beautiful. Average length ofthe test Y^g- to 2^^ inch
