the base of the second cubital cell, second at about one-sixth 

 from the base of the third cubital cell. 



2 ■ Head smooth and shining, slightly convex, a little longer 

 than the greatest breadth, slightly narrowed posteriorly, with a 

 short frontal sulcus. Thorax much narrower than the head ; the 

 pronotum nearly a,s long as broad, the sides almost parallel, with 

 a very broad and deep longitudinal groove dividing the segment; 

 scutellum narrow, longer than broad, pointed at the base ; dorsal 

 surface of median segment as long as the scutellum. Dorsal seg- 

 ments of the abdomen narrowly depressed at the apex, second 

 segment with four transverse carina?. Pygidium lanceolate, very 

 narrow. 



Hah. Yallingup, S.W. Australia ; November. Kalamunda, 

 S.W. Australia; February to April. <3 £ in cop. The female 

 is the type. 



The male is extremely near A. beatrix Turn., and is only dis- 

 tinguished from that species by the rather shorter antenna?, the 

 move convex and subcarinate scutellum, and by the somewhat 

 different yellow markings, which however are subject to con- 

 siderable variation. The female, on the other hand, is easily 

 distinguished from that of beatrix by the broad groove on the 

 pronotum and the longer and narrower head. 



The males in this genus and in Zeleboria are often extremely 

 near each other, and the species are not always easy to divide in 

 that sex.
