1116 ON THE CARENIDES, ^VITH DESCRIPTIONS OF NEW SPECIES, 
bluish-green ; head and thorax Vjlack, the edges of the latter 
suffused with blue. Head subquadrate (4 x 5), rather narrowed 
Vjehind the eyes, with one supra-orbital puncture on each side ; the 
frontal sulci deep, diverging backwards behind the supra-orbital 
puncture, and in front turning out sharply towards the anterior 
angles of the head. Prothorax transverse (4x6), rounded on the 
sides and at the posterior angles ; the anterior angles obtuse and 
slightly advanced ; the sides and base with a reflexed margin 
w'hich is wider on the base, base sublobate, emarginate in middle ; 
a rather sharp emargination outside each lateral angle of the base 
making these angles very distinct, and giving to the base its sub- 
lobate appearance ; median line distinct ; a marginal puncture 
near each anterior and posterior angle. Elytra ovate (11x6), 
not very convex, truncate at the base, rounded on the sides, 
distinctly striate, with two discoidal punctures towards the apex ; 
the lateral margins narrow, thickened and upturned at the humeral 
angles; a single row of punctures on the base, and along the lateral 
margins. Anterior tibiae bidentate externally ; the projections of 
the exterior ridge (four) feeble. 
Zoc. — Coonamble dLstrict, and Coonabarabran, N.S.W. Taken 
in sandy soil in June last. 
This species comes near 6'. ianthinum, Mach, from which its 
flatter form, more strongly striate elytra, and the different shape 
of the basal pai’t of the thorax will serve to distinguish it.
