middle, thence converging gradually to base, more steeply 

 towards apex, all angles obtuse ; disc with large and scattered 

 punctures on posterior half, finer and closer at sides and apex, 

 a smooth medial line on basal half and two small foveae at 

 base. Scutellum elongate-triangular, a large fovea on 

 anterior, a few deep round punctures on central part. Elytra 

 little widened behind shoulders and middle, three and a half 

 times the length of prothorax, rather widely rounded behind, 

 posterior margins serrated, the apices bidentate with small 

 semicircular excision ; punctate-striate, the intervals gently 

 convex at middle, sharply so at sides and apex, a little 

 wrinkled and sparsely punctate. Sternum with large round 

 punctures close and regular ; abdomen with much finer and 

 closer punctures and almost glabrous. Tarsal hooks simple. 

 Dim., 21 x 9 mm. 



Hah. — South Australia (Blackburn Collection). Type 

 (unique) in South Australian Museum. 



A single female in the South Australian Museum is 

 superficially like alexandri, but differing widely as follows: — 

 (1) Wider and more robust form; (2) abdomen green-bronze; 

 (3) apices of elytra more widely rounded and simply bidentate, 

 not strongly spinose. From rohiista, Saund., besides great 

 differences in colour, it differs widely in form, being more 

 elongate, with a quite different apical structure. The pre- 

 medial fascia is concave towards the front and leaves a space 

 of three elytral intervals at the sides ; the postmedial fascia 

 leaves only one interval uncovered on each side. I have much 

 pleasure in naming a South Australian species after the 

 scholarly entomologist who did so much to extend our know- 

 ledge of the insect fauna of Australia.
