OBSERVATIONS ON SCALE-INSECTS. 195 The synonymy given above is, I believe, correct, the determination being based upon an examination of material received from both Morgan and Maskell. A co-type $ from Morgan in my collection was originally mounted in Canada balsam without staining, so that the true form of the strikingly characteristic squamae on the pygidium of the $ could not be detected and was thus overlooked by Morgan in the first instance, and subsequently also by Leonardi, to whom I sent my example for examination, and for the purpose also of figuring it in his memoir (I.e.). In 1906 I had occasion to stain the female given to me by Morgan for comparison with examples submitted to me by Kotinsky, on Ficus sp., from Honolulu. I then found that the squamae were strikingly different from what they appeared to be when unstained. Subsequently I stained and mounted an example of Maskell's A. longispina var. omata and found it to be specifically identical with Morgan's co-type female. Clearly therefore the specific names maskelli of Cockerell and omata of Maskell must sink. Aspidiotus (Chrysomphalus) apicatus, sp. nov. Female Puparium. More or less circular, convex and very thick; covered with a relatively thick epidermal layer of the bark ; colour, when denuded, opaque black, larval exuviae nude, shining black, forming a well defined nipple ; second exuviae black ; ventral surface shining black. Ventral pellicle rather stout; white or dusky white, with a dark brown or blackish periphery. Diameter, 1*6-1*9 mm.

Female, adult (fig. 17, a). Broadly ovate, with a well marked and rather highly chitinised, cephalic projection, and immediately below it a minute spiny process (fig. 17, b). Margin of body more or less strongly and finely crenulated. No parastig- matic glands. Pygidium (fig. 17, c) broadly rounded, with a well marked callosity extending along it proximally, from which there arises on either side a somewhat
