SCALE INSECTS (" COCCIDiE ') OF AUSTRALIA. 19 



Sphaerococcu.s tnrhinata, ii.sj). 

 These galls were received from Mr. A. M. Lea, collected near Launceston, 

 Tasmania, u]ion the twigs of an undetermined species of Melaleuca. 



They are light brown, smooth, turbinate galls, spotted with tiny black 

 dots, slightly over half an inch in height, and three-eighths of an inch in 

 diameter. The basal portion forms a short stout stalk or peg, broadly 

 rounded to the apex, which forms a conical point. The\ have a large basal 

 orifice on the side of the stalk, opening into a large chamber, the internal 

 structure resembling that of Sphaerococcus piirogallis, Mask. These galls, 

 usually formed in clusters of three or four on the small twigs, might easily 

 be mistaken by the casual observer for seed capsules. 



The adult female coccids had been so badly damaged by hvmenopterous 

 parasites as to render their description impossible.
