21. Chionaspis citri, Comstock; 2nd Rep., Dep. of Entom., Cornell Univ., 1883. _Chionaspis euonymi_, Comstock (in part); Ag. Rep., 1880, p. 313. N.Z. Trans., Vol. XVII., p. 1884, p. 23. (Plate VI., Fig. 1.) Female puparium dirty blackish-brown, with a grey margin; elongated. "There is a central ridge from which the sides slope like the roof of a house" (Comstock). Male puparium white, narrow, carinated. Adult female yellowish-white, elongated, segmented. Abdomen ending in six lobes, of which the two median are the largest: these two are divergent. Along the edge some spines. No groups of spinnerets: a few single ones. Adult male unknown. Habitat--On oranges sold in the shops, imported from Sydney. This insect, apparently an importation from America, was not observed prior to 1884, and occurs as yet only sparingly, mingled with _A. coccineus_, from which it is easily distinguished by its elongated puparium. 22. Chionaspis dubia, Maskell. N.Z. Trans., Vol. XIV., 1881, p. 216. (Plate VI., Fig. 2.) Female puparium white, flat, elongated, pyriform, very thin; the pellicles rather small; length, about 1/12in. Male puparium white, elongated, rather oval; very slightly carinated above; on the under-side are two longitudinal keels. Adult female yellow, elongated, segmented; the abdominal segments somewhat deep. Abdomen ending with a median depression; terminal lobes inconspicuous (absent?). Five groups of spinnerets: uppermost group, six to ten orifices; the rest, ten to fifteen. Adult male reddish in colour. Antennæ hairy, 10-jointed, the first two joints very short. Feet normal, with four long, fine digitules. At the base of the abdominal spike is a somewhat large tubercle. Haltere of normal form, but the terminal seta is very long, four times as long as the thick basal portion, and has no terminal knob. Thoracic band conspicuous. The thorax is somewhat long, so that there is a considerable distance between the first and second pairs of legs. Habitat--On _Coprosma_, _Rubus_, _Asplenium_, _Pellæa_, Riccarton Bush and North Kowai River, Canterbury; Auckland. The female puparium resembles that of _C. aspidistræ_ (Signoret) and _C. populi_ (Bärensprung), but the abdominal segment of the female differs from both. 23. Chionaspis dysoxyli, Maskell. N.Z. Trans., Vol. XVII., 1884, p. 22. (Plate VI., Fig. 3.) Female puparium thin, flattish, pyriform, white in colour, with a faint pink tinge when the egg-mass beneath shows through it; length, about 1/12in. The second pellicle is comparatively large. Male puparium white, narrow, carinated; length, about 1/36in. The insect affects principally the leaves of the plant, and the puparia are usually clustered thickly along the midrib.
