Head deeply punctate, widely channelled between eyes, colour 

 darker on clypeus than on front. Prothorax: length 4mm.; width 

 at base 7 mm., at apex 4 mm. Anterior margin produced, 

 anterior angles acute, sides widely rounded, posterior angle acute; 

 base strongly sinuate, median lobe produced backwards and 

 foveate near scutellum; junction of middle and lateral lobes 

 marked by a triangular notch on basal border. Disc very convex, 

 central region humped, thence strongly declivous anteriorly, less 

 steeply declivous towards sides and base. Finely and regularly 

 punctate; without central canal. Scutellum blue, cordate and 

 depressed in centre. Elytra 17 x 8*5 mm., widest at posterior 

 third, wider at base than prothorax, sides slightly sinuate, apex 

 strongly bidentate, inner tooth spinose (formed by elongation of 

 suture), slightly longer than exterior tooth and apparently 

 elevated. (This appearance due to convexity of disc near apex). 

 Suture divergent at apex. Disc striate-punctate, punctures in 

 striae large and close, intervals convex. Yellow, except for oval 

 apical patch blue, and red margin, the former (blue patch) 

 narrowed near apex, then suddenly widened to include the 

 exterior tooth. Exterior four intervals near apex sanguineous, 

 the red margin narrowing to a single interval on sides, but not 

 quite continued to base. Beneath: sternum deeply and regularly 

 punctate, first segment of abdomen moderately punctate, last seg- 

 ment closely but more finely punctate; other segments minutely 

 punctate. Dimensions — 21-22 x 8-8*5 mm. 



Hab. — Cairns district, N.Q. (Mr. Henry Hacker). 



I am indebted to Mr. Hacker for a pair of this as of the follow- 

 ing fine species. I have been unable to find anything like either 

 amongst the numerous species hitherto described, nor are they 

 known in the British Museum, whose fine collection, recently 

 enriched by the addition of Mr. Kerremans' collection, I have 

 lately examined. The apparent elevation of the apical portion, 

 due to the pre-apical convexity, combined with its colour, and 

 strongly bidentate elytra will sufficiently differentiate it.
