Head — Labrum and epistoma minutely-punctate, front 

 nearly smooth, eyes distant less than the basal-joint of an- 

 tennae, without ocular sulcus ; antennae very slightly enlarged 

 apically, joint 1 rather long and stout, 3 longer than 1 and 2 

 jointly and as long as 4 and 5 combined, 4-10 subequal in 

 length, successively more obconic, 11 narrowly-obovate. Pro- 

 thorax 3 x 4*5 mm,, truncate at apex, bisinuate at base, widest 

 at base (this one and a half time,s the width of apex), sides 

 feebly curved and converging to apex ; disc minutely and 

 closely punctate (punctures only visible under a lens), anterior 

 angles obtuse, posterior acute (seen from above). Sculellum 

 triangular, black. Elytra convex, seriate-punctate, with eight 

 rows (besides a short scutellary row) of subfoveate punctures 

 of uniform size (scarcely smaller or less-deeply impressed to 

 the apex) ; intervals subconvex, finely but distinctly punctate; 

 sternum smooth, abdomen rugosely-longitudinally wrinkled. 

 Dimensions — 10-14 x 6-7'8 mm. 



Hab. — Queensland: Cairns, Bloomfield, etc. 



This is the species referred to in my monograph as near 

 obtusus, Pasc, and tristis, Fab., but the seriate punctures are 

 distinctly and uniformly larger, and are not placed in striae, 

 the intervals are less convex, and the colour a distinct-green, 

 sometimes with a slight tinge of purple. The interval between 

 two punctures is less than the diameter of one. Evidently a 

 common species and liable to be confused with G. nobilis, 

 Blackb. (in which the punctures are purple at bottom), but 

 the bifid mandibles will easily distinguish regius from C. 

 nobilis. Type in the author's collection. 



Amarygmus erubescens, n. sp. 



Ovate, convex ; whole upper-surface reddish with green 

 metallic reflections (the green predominating on head and pro- 

 notum) ; underside reddish-brown, legs metallic-black, antennae 

 piceous, tarsi flavo-setose. 



Head distinctly and closely punctate, eyes widely sepa- 

 rated by a distance greater than the length of basal- joint of 

 an antenna; the latter slender at base, joints 7-11 moderately 

 enlarged, 3 scarcely as long as 1 and 2 combined, 4-6 short, 

 7-10 longer than 6, 11 obovate. Prothorax 2 x 3 J mm., trun- 

 cate at apex, bisinuate at base, widest at base, strongly and 

 subarcuately narrowing at apex ; anterior angles obtuse, pos- 

 terior acute; disc rather strongly punctate, with a smooth 

 medial line indicated. Scutellum triangular and punctate. 

 Elytra very convex, narrowly ovate ; seriate-punctate, with 

 eight rows (besides a short scutellary row) of large round punc- 

 tures (rather larger than but similarly placed to those in A.
