second (counting at l)ase) obsolete on basal declivity; interstices 

 lightly convex, ninth (counting at apex) narrow, merging with 

 margin near base. Length 6, breadth 3 mm. 



Hab. — Tasmania : Magnet(Colls. Lea and Sloane). 



My description is founded on a single specimen given to mn by 

 Mr. A. M. Lea. It is a reniaikable species, with the facif^s of 

 an Oodes, and apparently has no resemblance to any other mem- 

 ber of the tribe lUigadoj^iui. Its discovery brings this tribe into 

 the Australian fauna, and so leaves little doubt but tliat Nebrio- 

 soma is a genus thereof. 



Subfamily HARPALIN.^. 



Tribe Brosciiii. 

 Genus G n a T h o x y s . 



Gnathoxys sulcicollis, n.sp. 



Robust, convex; front and clypeus deeply biimpressed; pro- 

 thorax subparallel on sides, strongly constricted near base, not 

 bordered on base, a deep wide marginal sulcus along each side; 

 elytra ovate, seriately punctate-foveate; anterior tibite 3-dentate 

 externally above apex; prosternum glabrous in front of C( xaj, 

 intercoxal part wide, longitudinally concave in middle, truncate 

 behind, setigero-punctate on each side. Black, upper surface 

 with light bronzy reflections. 



Head large^3-3 x 3-9 mm.), smooth, convex, transversely im- 

 pressed on a level with base of eyes; front a little raised above 

 plane of vertex; frontal spaces convex, lateral ones tapering 

 anteiioily; frontal sulci deep, wide, parallel, extending from 

 opposite middle of eyes nearly to anterior margin of clypeus; a 

 deep stria extending obliquely forward at each .side from eye to 

 base of clypeus and dividing the supra-antennal plates from the 

 lateral frontal spaces; clypeal suture deeply impressed across 

 median frontal space; clypeus deulivous to labrum, truncate, very 

 deeply longitudinally fossulate in middle; a puncture on each 

 side at anterior extremity of frontal sulci; eyes round, con\ex.
