452 REVISIONAL NOTES OX AUSTRALIAN CARABID^, 



sliagreened under a lens, third interstice bipunctate, liumeral 

 angles marked but not dentiform; metepisterna quadrate, nob 

 longer than broad, bearing a fe\v(tlu"ee or four) punctures; 

 anterior tarsi with second and third joints very widely dilatate. 

 Black, shining; antennte and tarsi ferruginous. 



Head elongate(l-8 mm. across eyes), convex; eyes prominent, 

 distant from anterior angles of prothorax. Prothorax broader 

 than long(2-63 x 3 6 mm.), widest about basal fourth, much 

 narrower at apex(l-9 mm.) than at base(3 mm.), siibdepressed 

 towards base, shining, but minutely shagreened under a lens; 

 sides lightly arcuate, subobliquely narrowed anteriorly; apex 

 lightly emarginate; anterior angles not prominent, obtuse but 

 marked; base lightly trisinuate; basal angles sharply marked 

 but obtuse at summit; lateral liorder narrow; median line faintly 

 indicated on disc; a lightly marked basal impression on each 

 side opposite fourth interstice of elytra. Elytra shining, a little 

 wider than prothorax(G x 3-8 mm ), liglitly convex; sides lightly 

 rounded, bending in a long gentle curve to apex; strife finely 

 crenulate, extending in full depth to apex, 4-7 not reaching 

 base, sixth and seventh terminating abruptly some distance 

 from base, seventh strongly impressed; second, fourth, and 

 sixth interstices wider than the alternate ones. Prothorax with 

 a few punctures on each side; episterna smooth but bearing a 

 number of strong punctures. Mesepisterna strongly punctate. 

 First and second ventral segments punctate, 3-6 smooth; sixth in 

 (J with a setigerous puncture on each side of middle, in 9 with 

 four .setigerous punctures near apical margin. Lengthd^- Roe- 

 buck Bay) 10, breadth 3-8 mm. 



9. Differs from ^ l)y upper surface opaque, owing to being 

 far more strongly shagreened. Length(9. Shark's Bay) 8-2, 

 breadth 3*6 mm.

I owe two specimens of this species to the generosity of Mr. 

 C. French. It is evidently a much narrower species than G. 

 thoracicus Oast., unknown to me in nature, and which Chaudoir 

 describes as resembling C. oviformis Chaud., not tnore elongate.
