Sphaerococcus pulc/ielhis, Maskell (Fig. 11).

This coccid forms a curious test, somewhat like that of an adult female 

 Eriococcus, upon the branchlets of an un- 

 determined Melaleuca growing in swampy 

 localities. 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 , , „

 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 abdominal 

 segments.
