then obliquely narrowed to apex, subsinuate near the denticu- 

 late posterior angle, anterior angles depressed and acute ; 

 irregularly punctate, the punctures coarse and close at sides, 

 sparse at base, close and fine towards apex, medial line 

 smooth. Scutellum scutiform, depressed, and smooth. Elytra 

 rather flat, more than twice as long as wide, of same width as 

 prothorax at base, strongly attenuated behind, with apical 

 margins serrated, each apex with a strong oblique lunation 

 with a long external and short sutural spine ; striate-punctate, 

 intervals nearly flat, densely and finely punctate. Prosternu m 

 closely, mesosternum coarsely, metasternum and abdomen 

 very finely punctate and sparsely pubescent. Dim., 16-19 

 x 6-7 mm. 



Hah. — Western Australia: Mullewa and Cunderdin 

 (Miss J. F. May and Western Australian Museum). 



Four specimens, one male, three female, vary in their 

 elytral pattern ; the three females are coloured as above, 

 except that in one example the antemedial spots are narrowly 

 connected to form a fascia, while in another the postmedial 

 fascia is narrowly interrupted at the suture. In the male 

 the only dark markings are a small spot on each shoulder, a 

 small postmedial spot halfway between suture and sides on 

 each elytron, and the extreme apex narrowly. There is no 

 doubt as to the conspecinc nature of the four examples. The 

 male and one female were on the same card in Mr. Lea's 

 collection from Mullewa; the other two, similarly labelled, 

 from Cunderdin, were sent respectively from the South Aus- 

 tralian and Western Australian Museums. The species are 

 nearest to jekellii, Sauiid., from which it differs markedly in 

 the wider basal two-thirds of the elytra, with its more attenu- 

 ated apical third, and the strongly spined apex — this somewhat 

 as in semicincta, C. and G., and variopicta, Thorns. The 

 pattern is also different, the suture without any coloration. 

 Type male in Mr. Lea's collection; female in South Austra- 

 lian Museum.

Elongate-ovate, rather flat. Head and pronotum bronzy- 

 black, antennae and apex of the former blue, the sides of the 

 latter bordered red or orange ; elytra blue-black, varied with 

 yellow or red as following ; two large rounded or oval basal 

 spots not extending to the base, an undulating medial fascia 

 narrowed near but not reaching the suture and produced 

 laterally to the humeral angle, a narrower arcuate postmedial 

 fascia not reaching the suture and produced laterally (in one
