4. acuta. 



PI. Til. figs. 2 & 4; PI. VI, figs. 13-14. 



This species is also a little variable as regards the apical mar- 

 gin af the tegmcn. In some examples it is slighth- but distinctly 

 concavely emarginate, in others slightly convex, and it varies a 

 little as regards the prominence of the sutural angle. The ova in 

 sitn and the last nymphal instar are figured on PI. VI, figs. 17-20. 



5. brcviceps. 

 PI. Ill, fig. 2. 

 Allied to acuta, not to acutipciniis. 



6. graiiulicollis. 

 PI. IV, fig. 2 & PI. VI. figs. 7-8. 



The vertex, in what I suppose to be this species, is usualK- 0I)- 

 tnse-angled. but varies from that to being distinctly rounded. 

 The scutellum is shorter than in the other species, the disk is 

 typically brownish-red with one longitudinal green stripe. 



Length: 5 to 5% mill. 



Hab. New South Wales. Sydney (Jan. -Feb.) Alittagong (Jan.") 



The 6". iniinita of Melichar is perhaps a varietv of this, intro- 

 duced into Saint Helena. In all the species of Siphanta I have 

 seen, the apical margin of the tegmen is always spotted with 

 crimson, though sometimes extremely faintly, as probably is the 

 case with S. niinuta. 



7. lucindae. 

 PI. l\\ fig. 3 & PI. VI. figs. 5-6. 



8. granulata. 



PI. IV, fig. 4. 



Very close to the last, but yellower, and more granulate on the 

 corium. 



9. subgranulosa. 

 (=zgranitUcoUis Kirkaldy olim. nee Stal) 

 PI. V, fig. I & PI. VI. f. 12. 

 Hab. Queensland. Cairns (July- Aug.. P.). Bundaberg (June 

 P.). This possibly =S. rubra Schmidt.
