616 NEW AUSTRALIAN SPECIES OF CARABIDiE 



generally in size and appearance; but from M'liich it differs 

 notably by its brighter colouring (C. diyglesi liaA'ing the uppei- 

 surface of the head merely showing some obscure purple reflec- 

 tions, mentum wholly black, guise purple; under-parts of pro- 

 thorax, inflexed part of elytra, and ventral segments obscurelj' 

 purple; mesosternum and metasternum wholly black): head 

 larger, with preocular sulcus far more strongly marked, eyes 

 more depressed, labial palpi far less securiform, median tooth of 

 mentum longer, narrower, and more strongly kee^; prothorax 

 shorter (in C. digglesi, 3*8 x3 8 mm.), anterior angles advanced 

 (in C. digglesi, not the least advanced); elytra with inflexed 

 margins wider anteriorly; anterior femora narrower, much less 

 strongly sinuate before apex on lower side, etc. Compared witli 

 C. qnadripunctatum Macl., the palpi are similar, but have the 

 apical joint of the labial less securiform; antennae shorter, basal 

 joint shortei", joints 6-11 shorter, more moniliform, less pubescent. 

 This is the only Carenum known to me, which shows any bright 

 colouring on the legs.

Head large (3"65 mm. across eyes), convex, transversely im- 

 pressed behind vertex; frontal sulci long, hardly divergent back- 

 wards, united at posterior extremities by a light curved impres-

 minent ; preocular sulcus obsolete ; eyes convex, prominent, 

 strongly enclosed behind, moie piominent than postocular part 

 of orbits, these rather prominent. Prothorax hardly as long as
