8a Frons medianly emarginate at base, with a median and a cir- 

 cular keel 8 Orinda 



Chlainydoptcry.v gen nov. 



Allied to Sai'inia Mel., but ihe venation is different. Head and 

 pronotum not at all flush. Circular keel of frons continuous and 

 the apico-lateral part of frons a little lobate. Frons granulate 

 around the keel. Fore tibiae somewhat widened. Type vidtiir- 

 nus. 



I. vulturnus. 



PI. VII, figs. 15-16. 

 Issus viilfiiniiis Kirkaldy. 



2. ridicularius. 



PI. VII, figs. 12-14. 



Jssus ridicularius Kirkaldy. 



In both these species, part of the frons is visible dorsally, the 

 base of the rounded basal carina being visible above as a straight 

 keel ; vertex almost truncate basally. The outer branch of the 

 radial vein is strongly arched basally. In C. ridicularius, the 

 clypeus is striate, a character however probably not very im- 

 portant. 



5. curobiuin sp. nov. 



Allied to the last, but the colour is browner. Vertex more 

 transverse, the apical margin almost truncate, frontal keels very 

 feeble. Outer branch of radial angularly bent near the base, 

 as seen from above. 



Male : pygophor as in C. ridicularius. 



Length 5 mill. 



Hab. Queensland, Cairns (August). 



Apsadaropteryx gen. nov. 



Allied to Sariiua, but the subcircular keel of the frons is con- 

 tinuous except at the apical margin and the clypeus is slightly 

 striate; the veins of the tegmen are strongly marked and the 

 inner fork of the radial vein reforks well basal of the apex of the 

 clavus. Fore legs not widened.
