252 AUSTRALIAN PSYLLID.^, 



broad. Genitalia : {^) large, turned over back, lower genital 

 plate rounded, elongate; forceps broad at base, long, slender, 

 rather straight; penis hidden; upper genital plate rounded at 

 base, long, slender: (9) short, broad, thickly clothed with hairs,

jJab. — Gunnedah, N.S.W. (on Capparis Mitchelli: W. W. 

 Froggatt). 



This species was found in all stages of development, from the 

 bright yellow eggs to the winged psyllid, covering the underside 

 of the leaves of this shrub, the infested foliage looking as if it 

 had been coated with dust, from the number of larvae and larval 

 skins attached to the leaves. I have never seen this species 

 except on this one occasion, but it probably has a wide range like 

 its food plant.
