Lea — On Australian Coleoptera 283 



(ex('('])t knees) red; basal joint of antennae metallic green, five following joints 

 slunini.'' ])ui'})le, the others opaqne purple. 



Head with sparse and small punetnres ; with a shallow inter-oeular, triangu- 

 lar depression, each angle of which is marked by a small fovea. Prothorax about 

 twice as wide as long; each side with three large teeth: the largest one median, 

 the next apical and about half its size, the other and smallest one basal ; a fairly 

 large fovea on each side of middle, in line Avith antennae; punctures somewhat 

 large]- and sparser than on head. Scntellum triangular. Elytra much wider 

 than prothorax; each with three irregular foveae triangularly placed: the largest 

 about two-fifths from the base and one-third from the suture, the smallest not 

 quite half-way between it and the base, the other (a rather ill-defined one) 

 marginal ; with rows of rather distantly placed punctures, fairly large at the 

 base, almost disappearing posteriorly. Length, 11-5-12 mm. 



Hab. Australia (Blackburn's collection); Queensland: Kuranda (G. E. 

 Bryant). Type, I. 4181. 



From some directions the whole upper-surface appears dark metallic-green, 

 from others metallic-purple, except that some of the punctures appear as glitter- 

 ing green spots. On the type some of the under-parts of the tibiae are obscurely 

 reddish. The specimen from Kuranda (returned to Mr. Bryant) has the head 

 red to the base, the extreme base of elytra obscurely diluted with red, the knees 

 not green, and most of the tibiae reddish ; the punctures on its head are larger 

 than on the type, its inter-ocular depression is deeper, but its hind angle not 

 foveate, punctures on prothorax larger, less sparse, and somewhat crowded on the 

 largest tooth on each side, the elytral punctures are also larger. I believe the 

 differences to be individual, rather than sexual, and that each is a male.

Plate iv, fig. 1. 



$ Metallic purplish-blue ; a large spot at base of head, pronotum ( except 

 for a large medio-basal spot), prosternum, and parts of mesosternum and of meta- 

 sternum blood-red ; elytra flavous, a short portion of suture, a small space on each 

 side of scutellum, and ten isolated spots purplish-blue; parts of muzzle reddish, 

 five basal joints of antennae shining, the others opaque. 



Head with punctures of irregular size and irregularly distributed; a deej) 

 median line, from summit of clypeus halfway to base. Prothorax gently and 

 almost evenly convex, not much wider than long, each side with a large and fairly 

 acute tooth in middle, each angle with a smaller tooth, middle of apex conspicu- 

 ously incurved ; punctures sparse and small. Elytra much wider than base of
