204 AUSTRALIAN XKIIROPTERA, iii., 



Tribe CpeagTini. 

 In this Tribus, the Australian genera Protoplectron Ger- 

 staecker, Pse^tc^?o/b?'m^ca/eo Weele,and -£'6'cw7*a Navas may be placed. 

 I know the last-named genus only from the description, and 

 from a somewhat schematic figure of the forewing of the single 

 species referred to the genus, Escura diveryens Kavas (Bevista 

 d. I.Real Academia d. Cienc, Madrid, p.468, 1914). In the 

 same paper (p. 467), Navas has founded a new genus, F^evdo- 

 plectron^ for costatuin Banks. As I have stated in my "Austra- 

 lian Neuroptera," Part ii. (these Proceedings, 1915, p. 67), 

 costatuni Banks, is sj^nonymous with iinheciihis Gerst., and must 

 be placed in the genus Pseudofor7nicaleoWee]e. The synonymic 

 list of the species will stand as follows : — 



F smidofQrinicaleo niihemdns Gerst. 



Greayris 'imb^icida Gerst. 



Pseudojormicaleo jacohsoni W'eele. 



Protoplectron costatum Banks. 



Tcdiulns caligatufi Navas. 



PseiLdopJectron costatum Navas. 

 I have, at hand, material of the species from Japan, Formosa, 

 and Java; and I have seen a specimen of Ps. n^ihecidus Gerst., 

 from Australia. Therefore, I am quite sure that mj' determina- 

 tions are correct. The figure of the head and prothorax of 

 P setidoformiicaleo jacohsoni, given by Weele (Notes from Leyden 

 Mus., Vol. xxxi., p.26, 1909), is, unfortunately, not quite correct: 

 the markings on the prothorax, for instance, are figured too 

 distinctly.
