upward and then down, lower fork rather long, curving inward; 

 clavus short, clavical suture slender. Abdomen short, stout, 

 coming to a conical point at tip. Genitalia : ((J) short, lower 

 genital plate small, forceps short, upper genital plate small : (9) 

 very sliort, upper and lower genital plates short, pointed, covered 

 with tine hairs. 



Hnb. — Condobolin, Carrathool, N.S.W. (on "Warrior Bush," 

 Apophyllum anomalum; W. W. Froggatt). 



This species probably has a wide range in the western districts 

 where the "warrior-bush" grows. The eggs are clustered close 

 together and frequently extend over an inch down the twig; they 

 are so numerous that they tint the smaller twigs a bright yellow.. 

 The larvfe and pupa? discharge a white sticky secretion, which 

 envelopes them in a greyish-white mass, exactly like that of the- 

 common woolly aphis (Schizoneicra lanigera); beneath this the 

 insects are almost as thick as the woolly aphis under similar cir- 

 cumstances.

(Plate XV., fig. 13.) 



Eggs bright yellow, short and more rounded than usual, laid 

 in great clusters on the young foliage between the forks of 

 branchlets. The young larv?e crawl close together, seldom moving 

 at first, and are smothered with numbers of small black ants 

 {Leptomyrmex gracilis). 



Larva. — Head and thorax dull yellow, barred with light brown, 

 eyes red; antennae and legs semitransparent, the latter tipped 

 with fuscous ; abdomen reddish-yellow ; entire dorsal surface 

 lightly clothed with long hairs. Head and thorax conjoined^ 

 very broad, rather truncate in front, rounded behind. Antennae 

 short, standing on either side. Legs short, thick. Abdomen 

 small, truncate at base, rounded on sides to apex. 



Pupa similar in colour, except that the brown markings are 

 much darker. Head not as broad as thorax; wing-covers small; 

 abdomen much broader. Entire dorsal surface covered with 

 short hairs bearing a sugary honey-dew.
