The siitural ang^le is more acute in some examples than in 

 others. The vertex is usually roundly angulate, sometimes it is 

 distinctly angulate. It is to be noted that in examination, tlie 

 insect must be kept liorizontal, as the further the head is tilted, 

 the more angulate the vertex becomes to the view. 



Hab: Queensland, Bundaberg (xi); New South Wales, Syd- 

 ney (i-ii); introduced into the Hawaiian Islands. Melicliar 

 records it, possi'l)l\' in error, from Tasmania also. 



3. aciitipciiiiis, sp. nov. 



Closely allied to S. acuta, but the reticulations are less granu- 

 late, and different in form; the sutural angle more acute. Ver- 

 tex more elongate and more truncate anteriorly, lateral mar- 

 gins more parallel. Disk of wings immaculate, except that 

 sometimes there are one or two tiny red spec'ks. 



Length: 10^ mill. 



Hab: Queensland, Cairns (vi). Nelson (vii). 



4. hm'Iccps. sp. noy. 



Allied to S. aciitipciuiis, but the vertex is shorter than the 

 pronotum (or at least not longer) and rounded anteriorly. 

 Bright grass green, granules of corium rather closer and more 

 numerous than in .S'. acuta. 



Lengt'h: 8^ mill. 



Hab: Queensland, Bundaberg (vi). 



5. toga, sp .nov. 



Probably of same general form as S. palrucUs Stal,* but the 

 vertex is longer and the pattern different. Grass green, paler 

 beneath; a yellow longitudinal oblique stripe on the tegmina. 

 Apex of vertex, tibiae more or less sanguineous. 



Vertex and pronotum about the same length, the first named 

 forming a right angle anteriorly. Tegmina about three-fourtli 

 longer than wide, subparallel after the basal fourth, apical an- 

 gles rounded, not prominent. 



Length: 9-9^ mill. 



Hab: Queensland, Cairns (vii). Nelson (vii), Bundaberg (vi). 



The yellowish stripe is sometimes more or less blended with
