 Port Wilhmga (H. M. Hale), Lucindale (B. A. Feuerheerdt ) , Bordertown 

 (J. G. 0. Tepper), Summertown (Puliman) ; Central Australia: Lake Calla- 

 bonna (A. Zietz) ; Queensland: Karoongooloo Station (H. S. Allnutt) ; New 

 South Wales: Broken Hill (F. W. Shepherd, type locality) ; Western Australia: 

 Mullewa (Miss J. F. May). 



In this species the synthlipsis is narrower than in A. hyperion, stali, or 

 endyniion ; a more robust form and smaller head at once separate it from A. doris 

 and fieheri. The eyes of the male are occasionally much closer at the base of the 

 head than in the tj^pe; in one example the synthlipsis is 4 times in the vertex and 

 10 times in the width of an eye. Although the synthlipsis varies thus, the vertex 

 remains approximately the same, about 2-5 times in the width of an eye. 



The delicate colours of A. grains soon fade after death; the colouration of 

 fresh samples collected by Mr. F. W. Shepherd in New South Wales, and by 

 myself in South Australia, is as follows : Notocephalon very pale yellow, almost 

 white. Pronotum orange, paler anteriorly. Scutellum clear lemon yellow, pos- 

 teriorly suffused with orange. Metanotum and anterior part of upper side of 

 abdomen (as seen through wings) clear lemon yellow, posteriorly delicately 

 shaded with orange; sides of al)domen pale pink, the edges of segments shaded 

 with brown ; sternum yellow, underside of abdomen black, in parts yellow. Legs 

 pale, coxae, femora, and tibiae marked with brownish-black on inner surfaces.

S Head, including eyes, mu.ch narrower than the pronotum ; notocephalon 

 ochraceous, produced downwards and slightly outwards in front of eyes, the 

 anterior margin being truncate and a little concave, with a small projection at 

 each angle; anterior three-fourths with a median, punctured groove, on each side 

 of which is a swelling with an im.pressed line of punctures defining its outer 

 margin ; these tumidities converge anteriorly and meet in the middle of the front 

 edge of the notocephalic projection; synthlipsis 1-3 to lo times in the distance 

 between the anterior angles of the eyes, and 2-3 to 2-5 in the width of an eye; 

 face seen in profile, concave, so that the lower part of the eye projects in front of 

 it on each side. Pronotum white, posteriorly black or reddish, about 1-5 times 

 wider than long, with some indefinite punctures and an indistinct, coarse, 

 median carina, which vanishes posteriorly; hinder margin concavely incised; 

 lateral margins moderately oblique. Scutellum yellow or orange, anteriorly more
