708 LIFE-HISTORIES OF AUSTRALIAN ODONATA, NO. III. 



I Lateral lobe of labium very large, rounded Petalurinm. 

 Lateral lobe of labium small and narrow, with tip 

 variously shaped JEschninni: (including Phyllo'pttalia). 



In conclusion, I should like to express my thanks to my friend, 

 Dr. Ris, for first pointing out to me the similarity between the 

 ovipositors of Phyllopetalia and the true ^^schnince. The conse- 

 quent conviction that Phyllopetalia was a true jEschnine genus is, 

 I trust, happily vindicated by the present paper, on the evidence 

 of this truly remarkable nymphal form.
