lateral group of tubercles outwardly projecting, somewhat peg- 

 shaped, not triangular, nor flattened above; three of the 

 tubercles larger, two of these conjoined at base and situated 

 anterior to the middle, the third posterior to the middle, a 

 small tubercle situated in front of subapical impression, one 

 in the middle but below the other tubercles, one posterior to 

 the third large tubercle, and a smaller one posterior to the basal 

 impression. Elytra (8x4*5 mm.) little widened on the sides, 

 rounded to base and apex ; punctures small and regular ; with 

 regular rows of rather prominent granules and three rows of 

 tubercles ; first row of tubercles about twelve in number, small 

 at base, becoming progressively larger posteriorly, the last two 

 or three spiniform, the apical tubercle the largest, overlooking 

 the declivity ; the second row running backwards and outwards, 

 not quite reaching base, with about eight tubercles, the last 

 four spiniform, outwardly directed, extending slightly beyond 

 level of first row ; the third row with a large humeral and 

 second, or subbasal, tubercle, of about equal size, followed by 

 a row of eight, becoming progressively smaller, not extending 

 much beyond middle. Beneath very feebly convex, sub- 

 glabrous, without evident punctures. Legs simple. 



9 . Larger, more ovate ; elytra wider, more rounded, the 

 apex more produced, with tubercles smaller, the basal ones 

 mere granules, and rather more numerous ; beneath more 

 strongly convex. Dim. — Male, 12 x 4*5 mm. ; female, 14x6 

 mm. 



Hah. — South Australia: Lucindale (A. M. Lea), Kan- 

 garoo Island (J. G. O. Tepper). Type in South Australian 

 Museum. 



The Kangaroo Island specimens show practically no 

 clothing, but I cannot detect any difference between them and 

 the Lucindale specimens. In general appearance this species 

 resembles -4. adelaidae, Waterh., and is so named in some col- 

 lections, but the shape of the lateral prothoracic tubercles is 

 quite different from the species which is common about 

 Adelaide, and which I regard as adelaidae. A . simidator is 

 closely allied to A. trihulns, but that species is smaller, with 

 more acute lateral prothoracic tubercles and less- conspicuous 

 elytral granules.

(S . Large, elongate-elliptical, comparatively narrow.

 squames. 



Eostrnm short, the upper-surface openly concave, with a 

 deeper median impressed line ; lateral margins strongly convex, 

 declining towards apex and base ; oblique ridges evident,
