4. acuta. 



PI. III. figs. 2 & 4: PI. VI, figs. 13-14. 



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

 gin of the tegmcn. In some examples it is slightK but distinctl}' 

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

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

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



5. breviceps. 

 PI. Ill, fig. 2. 

 Allied to acuta, not to acutipcnnis. 



6. granitlicollis. 



PI. I^^ fig. 2 & PI. VI. figs. 7-8. 



The vertex, in what I suppose to be this species, is usuall\- ob- 

 tuse-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.

The 5". luiniita 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 witii 

 crimson, though sometimes extremely faintly, as probably is the 

 case with 6". iiiiituta. 



7. htcindae. 



PI. \\\ fig. 3 & PI. M. figs. 5-6. 



8. grannlata. 



PI. IV, fig. 4- 



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

 cerium, 



9. subgranulosa.
