Fuller records his specimens upon the twigs of Hypocalymma angusti- folia, in West Australia. Tests pale biscuit brown, formed of a waxy secretion deeply fluted on the apical section, which is cleft and surrounded with an impressed line ; the basal portion below smooth, the whole looking as if composed of two distinct parts. Length, one-seventh to one-twelfth of an inch. The enclosed female black, subglobular, filling the test; antennse and legs aborted; dorsal surface covered with many small , , â Fig. 11.âSphaerococcus pulchelius. tubular spinnerets. 377.

These coccids produce remarkable dark green subglobular galls, stalked at the base, swelling out on the sides with the apex cone-shaped. The whole surface of the gall is wrinkled, with no visible opening at the apex. They are found upon the leaves, and sometimes on the twigs of an undetermined species of Leptospermum, Mount Barker, West Australia. Diameter about one-sixth of an inch. Maskell also describes a sessile form on the leaves of an undertermined tree, under the varietalname of elongaius, which he also figures. These came from Albany, West Australia. Adult female dark red, form globular, fitting closely to the interior and covered with white meal; antennae and legs wanting; spiracles dilated at both extremities ; small circular spinnerets, and short hairs on the abdomin
