658 MONOGEAPH OF THE AUSTRALIAN CICADID^H, 



postcostal marginal space distinctly broadened towards apex; 

 clavus narrow; ten or eleven discoidal areas; fourteen or fifteen 

 apical areas. Wings with six apical areas. Abdomen obconical, 

 equal in length to head and thorax; last segment of female 

 below deeply emarginate. Leys normal, front femora spined 

 below. 



Type G. viridis, sp.nov. 



This genus is closely allied to Chlorocysta, but differs in the 

 much broader exterior ulnar area, the less acutely produced front 

 of head, and six apical areas in the wings. Like that genus, 

 there is a diamond-shaped vitreous area in the front margin of 

 the wing, at the origin of the first transverse vein. We have not 

 seen the male. 



*Glaucopsaltria viridis, sp.nov.

 and legs, green. Front greenish-yellow, rostrum yellow, reaching 

 middle coxa?. Lateral borders of mesonotum bordered with 

 white silky pubescence which unite on cruciform elevation and 

 extends for some distance on the abdomen. Long. corp. 20 mm.; 

 lat. 8 mm.; exp. teg. 68 mm.
