Female puparium double, the scales superimposed, first pellicle in the centre of the upper scale; male puparium elongated, not carinated Aonidia. Female puparium completely enclosing the insect; male puparium elongated, not carinated Targionia. Genus: ASPIDIOTUS, Bouché. Female puparium varying in colour; circular in outline, usually flat, sometimes rather convex; pellicles usually in the centre. Male puparium rather longer than that of the female, the pellicle at one end; not carinated above. Groups of spinnerets usually four, sometimes five, and in one American species (_A. sabalis_, Comstock) six; or, in a few cases, altogether wanting. Adult females usually peg-top shaped. 1. Aspidiotus Atherospermæ, Maskell. N.Z. Trans., Vol. XI., 1878, p. 198. (Plate IV., Fig. 1.) Female puparium circular, flat, brown; diameter, about 1/20in. The pellicles in the centre form sometimes a sort of boss or protuberance, of lighter colour than the rest. Male puparium oval, flat, brownish, about 1/36in. in length. Adult female light-yellow in colour, of the usual peg-top shape of the genus; length, about 1/30in.; corrugated--the last abdominal section, being very small, is much overlapped by the rest. Four groups of spinnerets, upper pair with fifteen orifices; lower pair, nine or ten. Abdomen terminating in several lobes, of which the four median are the largest; between the lobes scaly serrated hairs. Adult male unknown. Habitat--On _Atherosperma Novæ Zælandiæ_, Wellington; Hawke's Bay. 2. Aspidiotus Budlæiæ, Signoret. Ann. de la Soc. Entom. de France, 1868, p. 115. N.Z. Trans., Vol. XI., 1878, p. 198. Female puparium circular, flat, dirty-white, about 1/15in. in diameter. Male puparium oval, dirty-white, about 1/30in. in length. Adult female light-yellow, peg-top shaped; abdomen ending in two somewhat prominent lobes, with scaly hairs and spines. Four groups of spinnerets: upper groups with five or six orifices; lower groups, three or four. Adult male yellow, slightly brown on the thorax; antennæ of ten joints, all hairy. Habitat--On silver-wattle, Nelson. The insect is European, and found there on _Budlæia salicina_. Closely allied to _A. nerii_, but differing in the lobes and spinnerets of the abdomen. 3. Aspidiotus Camelliæ, Boisduval. _Kermes camelliæ_, Boisduval, Ent. Hort., p. 334. _Aspidiotus camelliæ_, Signoret, loc. cit., 1869, p. 117. N.Z. Trans., Vol. XI., 1878, p. 200; Vol. XVII., 1884, p. 21. (Plate IV., Fig. 2.) Female puparium nearly circular, convex, greyish or brownish in colour, about 1/15in. in diameter; pellicles often at one side. Male puparium rather smaller, oval.
