42 STUDIES IN AUSTRALIAN NEUROPTERA, ii., 



F.E S., of Sydney, Mr. E. Allen, of Emerald, Q., Dr. A. J. Turner, 

 F.E.S., of Sherwood, Brisbane, Q., and Mr. Rowland E. Turner, 

 of London, (from Yallingup, W.A.). To all of these, I offer my 

 sincere thanks for the valuable specimens received, without 

 which my collection would still be a very poor one indeed. 



Id this paper, eighteen species are proposed as new. One of 

 these belongs to the family Osmylidoi, one to the Ascalaphidce, 

 and the remaining seventeen to the Myrmeleonlid'e. This latter 

 family offers considerable difficulty to the Australian systematist, 

 chieHy because of the paucity of literature, the inaccessibility of 

 the types of the species already described (mostly by Walker, 

 Gerstaecker, and Banks), and also partly because of the close 

 resemblance between many of the forms. I desire, therefore, to 

 express my thanks to my friend, Mr. Esben Petersen, of SilUe- 

 borg, Denmark, for giving me his valuable opinion on a number 

 of the forms described in this paper, and also for his excellent 

 generic table, recently published in these Proceedings (1915, 

 Vol. xl., Part 1, pp.56-57), which I found of the greatest help, 

 particularly in assigning positions to a number of new genera. 



Four genera are proposed as new. No attempt has been made 

 to break up the complex genera Glenoleon, FonnicaUou, or Acan- 

 thaclisis, though Alloformicaleoii Esb.-Pet., has been accepted as 

 a valid genus. A new division of the subfamily Dendroleontince 

 into three tribes has been proposed, based on venational and 

 phylogenetic considerations. 



The following is a list of the genera and species dealt with in 

 this paper : —
