as the third; eyes converging a little towards the vertex ; 

 head finely and closely punctured, front with a distinct 

 lonjjitudinal sulcus. Pronotuni short and broad ; ])arapsidal 

 furr(nv3 very indistinct ; scutellum longer than broad. 

 ]\Icdian segment shorter than the pronotuni, oblicjucly sloped 

 posteriorly, with an almost obsolete median sulcus. Thorax 

 and median segment sabo|iaque ; abdomen shining, almost 

 smooth. Hind tibiae with three or four fairly long spines on 

 the outer margin ; fore tarsi without a conib, with only a 

 few very minute spines beneath the first joint; tarsal ungues 

 with a small tooth near the middle. Second abscissa of the 

 radius about equal to the third ; first recurrent nervure 

 received just beyond two-thirds from the base of the second 

 cubital cell, second at the middle of the third cubital cell. 

 Submedian cell a little longer than the median ; cubitus of 

 the hind wing originating distinctly beyond the transverse 

 median nervure. 



^ . Without the whitish band on the clypeus, the spots on 

 the inner margin of the eyes very minute, the apical dorsal 

 segment and a spot at the base of the hind tibire white. 

 Pronotum entirely black. 



Clypeus subtruncate at the apex; first recurrent nervure 

 received close to the middle of the second cubital cell ; fore 

 tarsi smooth. Antennte stout, the joints not arcuate beneath, 

 the second joisit of the fiagellura no longer than the third. 



Length 4 mm.

The ? is the type. 



This is very nearly allied to the European A. cinctellus, 

 Lind., tVom which it differs in the longer second joint of the 

 flagelluin, the less distinct sulcus on the median segment, 

 the longer third abscis.^a of the radius, the absence of the 

 yellmvish spots on the hind margin of the pronotum, and 

 the very slightly longer submedian cell of the fore wing. The 

 male cinctellus has the legs without ferruginous colour, 



A colour- variety taken by me at Yallingup, S.W. Australia, 

 has the clypeus of the female black, the frontal sj)ots almost 

 obsolete, and the pronotum entirely black. A male taken in 

 the same locality is black, with the middle of the hind femora 

 ferruginous and a white spot at the base of the hind tibia;.
