760 STUDIES IN AUSTRALIAN NEUROPTERA, vi., 



(type zebra Br.), invalidated by ZyyophlpMns Navas, 1910, (type 

 verranxinus Navas = eZe^mii? Guerin) itself a synonym for Arteri- 

 opfery.v Guerin, synonymous with P^ychopsis Newman. 



Having thus cleared the ground to some extent, let us now 

 pass to the consideration of the division of the family into tribes, 

 as proposed by Navas in 1916 (13, p. 188). I give herew^ith his 

 key, translated from the original Spanish : — 



(1) 



(2) 



Costal area of both wangs divided, at least partly, by a median 

 longitudinal series of gradate veinlets {reniUas en esculinata) 2. 



Costal area simple or totally undivided in both wings. Asiatic 



species 3. Balmesini, nov. 



Two anastomoses in both wings; the anterior formed by the 

 subcostal, the radius and its sector, which are united in the 

 region of the stigma, the posterior by the procubitus { = M), 

 the cubitus and its sector, which are connected in a similar 

 manner. African species 2. Zygophhhini Navas, restr. 



One evident anastomosis, viz., the anterior or radial, formed by 

 the three veins mentioned; the others run parallel without 

 bending manifestly in an anastomosis. Australian species... 



1 . Psychojjsmi, nov. 



In his description of Psychopsis hirmana{2), which Navas has 

 evidently not seen, McLachlan says: — "It differs from all Aus- 

 tralian species except Ps. 7ney?'icki in the absence of a line of 

 oblique connecting nervules in the costal area" ; and, lower down, 

 he divides the known species of Psychopsis into two groups, of 

 which the first, consisting of Ps. meyricki and Ps. hirmana, is 

 defined by the words "No line of oblique nervules in costal area, 

 only two series of transverse gradate veins." 



The facts of the case are that Ps. meyrirkl normally lacks the 

 costal series of cross-veins, as McLachlan here states. Navas, 

 however, who admits that he has never seen this species, is com- 

 pelled to place it in his geiuis Magallanes, together wdth Ps. 

 hisohns McLach., though he defines this genus as having the 

 costal space of the forewing subdivided by the presence of the 

 series of costal cross-veins, which Ps. meyricki lacks. For, if he 

 had anywhere mentioned this character, which McLachlan 

 emphasises, his tribe Balmesini at once breaks down !
