422 REVISIONAL NOTES ON AUSTRALIAN CARABID^, iv., 



though my specimen differs from the description of N. prist ony- 

 choides by having the third interstice of the elytra bipunctate, not 

 tripunctate ; but in my specimens of N. sphodroides, the number of 

 punctures varies from two to as many as four. 



17. NOTONOMUS ANGULOSUS, n Sp. 



( J. Oval, subdepressed. Prothorax subquadrate; basal angles 

 rectangular; posterior marginal puncture at inner side of basal 

 border near basal angle; elytra fully and deeply striate; inter- 

 stices convex, third 2-punctate, eighth lightly convex, wider than 

 ninth; humeral angles edentate. Black. 



Head large (3 -5 mm. across eyes); eyes convex. Prothorax 

 broader than long (4x4*5 mm.), wider across base (3*8 mm.) 

 than apex (3-5 mm. ), depressed towards base; sides lightly rounded 

 on anterior two-thirds, straightened posteriorly to meet base at 

 right angles; border rather strongly reflexed, equal, hardly indi- 

 cated on sides of base; lateral channel not reaching base; median 

 line well marked; lateral basal impressions elongate, wide? sulci- 

 form at bottom; lateral basal spaces depressed near basal angles. 

 Elytra truncate-oval (10x6 mm.), lightly longitudinally de- 

 pressed along course of third interstice; lateral apical declivities 

 well developed, tenth interstice hardly indicated. Intercoxal 

 declivity of prosternum rounded in middle. Tarsi : anterior with 

 three basal joints in $ dilatate and squamulose beneath; four pos- 

 terior with first joint costate externally without spinules beneath 

 costa. Length 16, breadth 6 mm. 



Hab. — Victoria. Type (unique) in National Museum, M elbourne, 

 ticketed "Gippsland." 



A very distinct species, resembling N. peroni Cast., in the shape 

 of the prothorax. The elytra are like those of N. tubericaudus 

 Bates, but the third interstice is not swollen at position of pos- 

 terior puncture. It is allied to N. politulus Chaud., and N. tuberi- 

 caudus by form of elytra, intercoxal declivity of prosternum, and 

 external side of first joint of the four posterior tarsi. 



19. N. tubericaudus Bates. — Easily identified; being the only 

 species with the third interstice strongly protuberant near apex. It
