median sinus deep, about two-thirds the width of each of the 

 lateral ones; with dense and very minute punctures, and 

 with fairly numerous large ones, but still small, becoming 

 larger towards the sides. Scutellum with very minute punc- 

 tures, and with a vague median depression. Elytra not 

 much wider than prothorax, post-humeral incurvature feeble, 

 apex bimucronate ; with distinct rows of small punctures in 

 feeble striae; the interstices with minute scattered punctures; 

 apex and sides near apex transversely or obliquely strigose. 

 Pygidium obtusely ridged transversely, densely concentrically 

 strigose. Heso sternal 'process produced to between front 

 coxae, with the apex almost equilaterally triangular. Front 

 tibial obtusely tridentate, the median tooth nearer the apical 

 than the subbasal one, the other tibiae each acutely dentate 

 about the middle. Length, 37 mm. 



Hab. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 1484, in South Australian Museum. 



Allied to bakewelli, but differs from female of that species 

 In being somewhat narrower, with the elytra and pygidium 

 entirely black, the former with more conspicuous rows of 

 punctures and apex less acutely bimucronate, prothorax with 

 a much smaller portion of the sides red (the red much the 

 colour of the elytral fascia of balteata), and front tibiae more 

 obtusely tridentate. The greatest width of the red margins 

 is slightly in advance of the middle, where it is almost the 

 width of the scutellum, but it is narrowed to apex, and does 

 not quite extend to the base. The hind coxae are vaguely 

 diluted with red. The type was obtained floating on a tub 

 f of water at Malanda.

cS . Flavous, shining ; sides of base of head, tips of 

 clypeus, prothorax narrowly at base and narrowly at middle 

 of apex, two longitudinal vittae, elytra at sides of scutellum, 

 suture, a spot on the shoulder, and an elongated one near 

 the apex of each elytron, most of the sutures of under-surface, 

 knees, tibial spurs, and teeth, and the tarsi black or blackish ; 

 antennae and palpi more or less reddish. 



Head with rather dense, small punctures, except on a 

 transverse shining line near base. Clypeus with somewhat 

 coarser punctures than on head; apex deeply notched, with 

 the tips acute, with a sublateral ridge from base to apex. 

 Prothorax with sides narrowly margined; median sinus 

 rather shallow, but little more than half the width of each 

 of the outer ones; with dense, minute punctures and fairly 

 numerous larger (but still small) ones. Scutellum with rather
