The recent appearance of three important memoirs by 

 Kis * and Tillyard f relating to the Odonata of the Austro- 

 Malayan region turned my attention to the Zygoptera of 

 a small lot of dragon-flies which I obtained a few years ago 

 purporting to come from Cape York, North Queensland. 

 From the character of the larger species in the collection, 

 there seems to be no reason to doubt the correctness of the 

 locahty. As far as I have been able to examine the smaller 

 insects, they appear to belong to described species with the 

 exception of one example which proves to be of rare interest 

 in respect that the proximal side of the quadrilateral is 

 absent in the fore-wing, a peculiarity, as far as I know, 

 hitherto considered unique in the Australian Hemiphlebia 

 7nirabilis, Selys. On sending a short account of this insect 

 to Dr. Ris, he informed me that he was acquainted with 

 nothing hke it either in nature on in the hterature and he 

 urged its early description. Subsequently when forwarding 

 some other material to Dr. Ris, I included the Cape York 

 insect. He confirmed his former view, and kindly volun- 

 teered to make wing photographs which hghten so much 

 the work of description. 



The species, of course, forms the type of a new genus. 

 Notwithstanding the important character above alluded 

 to, it cannot, however, he referred to even the same 

 Legion [Agrion) as Hemiphlebia, and it seems to find a 

 more natural place in the Legion Podagrion. The rather 

 heavy pterostigma, the character of the appendages and the
