NEW AUSTRALIAN SPECIES OF THE FAMILY 

 AGRIONIDjE [Neuroptera : Odonata]. 



By R. J. Tillyaru, B.A. 



(Plate xvii.) 



In this paper eleven species are added to the list of Australian 

 Agrionidce, bringing the total number recorded from 28 up to 39. 

 Of these, ten are new to science; the eleventh has only been 

 recorded before from tropical Africa, where it is common. All 

 the new species come from North Queensland. Two genera> 

 Alloneura and Ceriagrion, are added to the Australian list; and 

 one species, placed provisionally in the genus Ischnura, will 

 probably form the type of a new genus. Of the new species, 

 two each belong to Lestes, Alloxeura, Pseudagrion and Agrioc- 

 nemis, and one each to Argiolestes, Ischnura (1) and Ceriagrion. 



All these species were taken by myself during a trip to 

 Northern Queensland in the summer of 1904-5. One or two 

 were met with in abundance, and it is remarkable that they have 

 not been recorded before. Most of the species are, however, 

 exceedingly rare or local, and were only obtained after ceaseless 

 exploration of the same districts for days. The females of two 

 of them are yet to be discovered. 



I am greatly indebted to M. Rene Martin of Le Blanc, France, 

 for his kind aid and advice in identifying many of these species 

 as new; for it will be understood that only one who has a world- 

 wide knowledge of the Odonata, and especially of Polynesian 

 species, could with safety be relied upon to determine new 

 tropioal species and to fix their affinities. 



All the descriptions given were made either from the living- 

 insects, or from insects freshly killed, as this is the only possible 

 way of recording the true colours of our Odonata.
