I shall leave it now as distinct, though much nearer to M. leptospermi than anything else, and a probable link between that and M. pyriformis. On account of the bent shape which this insect takes, from curling round very small twigs, it is very difficult to extract it from its puparium without damage. Mytilaspis gloverii, Packard. M. gloverii, Packard (Comstock, Ag. Rep. 1880, p. 323). This insect has been sent to me from Melbourne, on a leaf of orange. I doubt its being really specifically distinct from M. citricola, Packard, the only difference apparently being in the narrower form of the female puparium. Professor Comstock, however, so definitely urges the separation of the two that I do not venture here to disturb his arrangement. Mr. Douglas (Ent. Mo. Mag., March, 1886, p. 249) considers M. citricola as identical with M. flavescens, Targioni. Genus Chionaspis, Signoret. Chionaspis dubia, Maskell. Scale-Ins. of N.Z., p. 54; N.Z. Trans., vol. xiv., p. 216. An insect which I consider to be only a small form of this species occurs at Reefton on leaves of Leptospermum, and at Wellington on Asplenium and Cyathodes. I find nothing except size which can be taken as a clear distinction: the female puparium averages about 1/24in. in length, and the pellicles are proportionately larger than in the type. The segments of the body are certainly more conspicuously prominent; but there is no character on which I feel justified in considering this form as even a variety. Chionaspis dysoxyli, Maskell. Scale-Ins. of N.Z., p. 55; N.Z. Trans., vol. xvii., p. 22. In my paper of 1889 (vol. xxii., p. 135) I mentioned the fact that the males of this species are frequently entirely apterous. I shall presently (vide post) have to report the same phenomenon in Eriococcus hoheriæ, and an almost similar condition in Leachia zealandica. There are thus three of our New Zealand Coccids having males abnormally developed. I regret that when writing last year I overlooked a paper by Dr. F. Löw (1883) on Leucaspis pusilla, in which that species is mentioned, together with Chionaspis salicis and Eriococcus (Acanthococcus) aceris, as having apterous males. My only excuse is that I read German with great difficulty. However, I see no harm in recording now a list of the few Coccid species reported as exhibiting this abnormal character. They are less than a dozen out of several hundreds of species known in different parts of the world: and the point is not
