upward then downward, upper fork rather straight, running out

Hah. — Bungendore, N.S.W. (on Eucalyptus sp. ; W. W. 

 Froggatt). 



Larva producing four or five broadly rounded fleshy galls from 

 I inch to 2 lines in diameter, and \ inch in height upon the 

 foliage of Eucalij'ptus sp. They are variable in form; the attach- 

 ment to the leaf is slight, but the whole of the base of gall is 

 flattened on the leaf, swelling out, rounded at apex, with from 

 three to six tubular cells, each containing a larva. When imma- 

 ture these openings are very indistinct. The colour of the galls is 

 variable, those exposed being brightly tinted with red and yellow; 

 those hidden or sheltered of a pale sea-green colour, but all are 

 clothed with a fine white plum-like bloom. 



Trioza carnosa, n.sp. 

 (Plate xvi., figs. 12 and 24.) 



Larva dark brown on dorsal surface, green shaded with yellow 

 on thorax and on ventral surface; eyes red; antenna? and legs 

 light brown: Outer margin of dorsal surface fringed with minute 

 ciliated spines, covered with white woolly filaments which rub off 

 very easily. Head small, imbedded in thorax but outlined with 

 a light yellow line and suture of same colour down the centre of 

 the back ; antennae very short, horn-shaped ; eyes very small. 

 Thorax and head combined forming a rounded shield ; tips of 

 wing-covers overlapping base of abdomen ; legs short, thick. 

 Abdomen arcuate on sides, rounded to apex. Ventral surface 

 rounded, abdomen showing segmental divisions, with a regular 

 upper edge or flange right round. 



Pupa similar in form and colouration to larva, with the wing- 

 covers much more prominent, and the outer margins more thickly 

 frinijed with white filaments.
