Hab.—'Sew Guinea; taken by Karl Wahnes, in March, 1900. 



This species, the only known representative of the genus in 

 New Guinea, is quite distinct from all the others, especially 

 because of its very long ovipositor, which seems to be still capable 

 of being used as a borer, judging by its shape. In this character, 

 it is certainly the most archaic member of the group. The 

 species is figured well in Martin's " Cordulines," Plate iii., tig. 20, 

 and the male appendages on p 84(fig.98). 



8. Synthemis claviculata Tillyard. (Plate iv., fig. 6). 



Tillyard, Proc. Linn. Soc. N. S. Wales, 1908, p.749((Jonly). 



A second male of this rare species, and a female, the latter 

 rather immature, have just been forwarded to me by my friend, 

 Mr. E. Allen, of Cairns. They were taken in the same locality, 

 near Kuranda, as the type-male. As this second male is in very 

 good condition, I have figured it in the plate, and append a brief 

 description.
