with a setigerous puncture near each external angle, a transverse 

 row of seven closely placed setigerous punctures in middle near 

 anterior margin, the outer of these punctures distant from the 

 lateral puncture; anterior margin lightly produced in the middle 

 into a short wide prominence (external sides of this prominence 

 opposite the outer puncture of the median row). Prothorax 

 rimose, a little broader than long (2-1 x 2-3 mm.), lightly con- 

 stricted by an arched impression in front, transversely impressed 

 near base; sides lightly rounded, shortly and lightly narrowed to 

 apex. Elytra oval (6-5 x 3-8 mm.), rough (granulate-punctate), 

 the white humeral parts smooth, granulation liner on the white 

 than on the green parts. 



9. A little wider than (^; the triangular ear-like processes of 

 the prothorax much stronger. 



Length 10-5, breadth 3-8-4 mm. 



Hab.—Q. : Mackay (Brown; Coll. Sloane). Mr. H. W. Brown 

 found this species at Mackay, and has given me two specimens. 



It differs from all other Australian species (unless C. trivittata^ 

 Macl., unknown to me in nature) by the form of the prothorax. 

 It evidently differs decidedly from C. trivittata by colour (not 

 reddish-coppery-bronze); elytra with sutural vitta only present on 

 the apical half, and with no broad twice-interrupted central vitta. 



DiSTYPSIDERA ORBICOLLIS, n.Sp. 



Slender, elongate, cylindrical; head and prothorax roughly 

 shagreened; prothorax with disc orbiculate; elytra punctulate, 

 without undulate sculpture. Head and prothorax emerald green; 

 labrum testaceous with narrow infuscate edge; elytra olive green, 

 brighter towards apex, a large lurid or tawny humeral patch 

 extending one-third the length on each elytron, posterior margin 

 of this patch projecting in the middle in the form of a wide 

 triangle, an infuscate basal space between the light-coloured 

 humeral plague, this space very narrow posteriorly, but wide and 

 subrotundate anteriorly. 



Head narrower than in other species (1-7 mm. across eyes); 

 eyes much closer together, especially in front. Prothorax granulate-
