58 AUSTRALIAN NEUROPTERA, ii., 



pointed apical part, almost a right angle. In the Australian 

 species, A. subtendens, A. fuiidata, A. fulva, A. suhfasciata, A. 

 maclachlarii, and A. mmulata, the spurs have no broad basal 

 part, and they are more or less gradually curved, not angular. 

 A. subtendens, A. fundata, A.Julva, and partly also A. sub/asciata, 

 agree with the A. occitanica-gvoup as to the shape and neuration 

 of wings, the strongly haired and sliort legs, the length of tarsal 



joints, and the habitual appear- 

 ance. A. maclachlani and A. 

 annulata, however, differ with 

 regard to their longer and nar- 

 rower wings, their shorter spurs, 

 and their relatively longer tibiae 

 and tarsal joints. In the neu- 

 ration o£ wings, there are also 

 differences. Navas has founded 

 a new genus, Cosina, including 

 C .maclachlani and C. neozela7id- 

 ica (the latter unknown to me); 

 but it seems to me, that the 

 generic characters mentioned by

Australian species in Aca^itha- 

 clisis, and place them in two groups : the A. fmidata-grouip, and 

 the A. maclachlani-grow^. 



Below, I give a Table of the Australian species known to me. 



l.In the hindwing, 6-8crossveins before origin of radial sector. Cuj runs 



into hind margin of hindwing opposite to, or behind, origin of radial 



sector (^./imda^a-group) 2. 



In the hindwing, 11-16 crossveins before origin of radial sector. Cu2 

 runs into the hind margin much before origin of radial sector [A. 



madachlani-groni>) 5.
