NEW AUSTRALIAN SPECIES OF THE FAMILY 

 AESCHNIDJE. 



[Neuroptera : Odonata.^ 



By R. J. Tillyard, B.A. 



(Plate lxviii.). 



i. Subfamily C0RDULEGASTERIN2E. 



No species of this subfamily has previously been recorded from 

 Australia. In December, 1903, Mr. G. A. Waterhouse took, 

 while collecting in the Blue Mountains, two dragonflies One of 

 these is in the possession of Mr. W. W. Froggatt; the other was 

 sent home to England for identification, but has not since been 

 heard of. Some time ago I noticed the dragonfly in Mr. 

 Froggatt's collection, and requested him to allow me to send it to 

 M. Rene Martin of France, as I believed it was a new species. 

 M. Martin was much struck with the beauty and peculiarity of 

 the insect, and forwarded it to Dr. Ris of Belgium, who pro- 

 nounced it to be Petalia Apollo £, a rare insect, so far only known 

 to occur in Ohili; he was also strongly of opinion that there had 

 been some mistake as to locality until I convinced him of the 

 truth of the capture. If we have in Queensland a dragonfly 

 (Ceriayrion glabrum) whose only other known locality is Central 

 Africa, it need hardly occasion surprise that we should also have 

 on the Blue Mountains a dragonfly that until now had only been 

 known to inhabit the Andes. 



As the insect is a most remarkable and beautiful one, I append 

 a short description : — 



Petalia Apollo Selys. 



J. Total length 59 mm.; abdomen 44 mm.; wings, fore 39 mm., 

 hind 37 mm. 



Wings pointed, forewings rather narrow, reticulation rather 

 open; basilar space free, hyper trigonal space with one cross- 

 nervure. Triangles short, broad, once crossed; a large open cell
