upward, upper fork emerging above tip of wing, lower fork below 

 forming an angular cell; lower branch of cubitus long, upper fork 

 large, curving round, with lower fork forming a large cell; clavus 

 stout, clavieal suture indistinct, fine stria) very distinct between 

 cubital, and on 2nd cubital cell. Abdomen small, slender, deeply 

 wrinkled on sides. Genitalia : (^J) short, stout, turned up over 

 back; lower genital plate broad, rounded ; forceps short, with a 

 curved black conical tip; upper genital plate large, swollen in 

 -center, curving inward at tips : (9) valves short, blunt. 



Hah. — Gympie, Queensland (on foliage of Tristania conferta; 

 W. W. Froggatt). 



The larvae produce circular, squat, funnel-shaped galls upon 

 the leaves, sometimes scattered and single, but frequent!}' so 

 clustered together that the infested leaf becomes curled and 

 aborted; many trees have nearly every leaf more or less infested. 

 The base of the gall springs direct from the leaf, the larva being 

 attached by its rostrum to the bottom, with the edges rising up 

 and forming a saucer-like rim above its back, var3n'ng from pale 

 green to yellow in colour, and measuring up to 2| lines in diameter 

 and r| in height above the leaf. At first sight, being covered 

 with the white floury exudation, they might easily be taken for 

 the galls of one of the Brachyscelinse. A number of specimens 

 were bred out in October. 



Genus G e u e r l y m a, g.n. 



Head wide across, vertex produced into two slender points, 

 closed or open at apex; face lobes wanting; antennae long, slender. 



Thorax : pronotum narrow, dorsulum very broad through 

 centre, mesonotum and scutellum large and raised. Elytra very 

 broad in proportion to length, curved round on front margin like 

 a bow, rounded at apex; stalk of subcosta much longer than stalk 

 of cubitus, subcostal cell and stigma wanting, radius long, 

 emerging at tip of wing ; cubitus short ; furcations of both 

 branches long. 



The absence of face lobes places this genus close to Tyora, 

 though the wings are very distinct. Type, Geijerolyma rohusta.
