446 REVISIONAL NOTES ON AUSTRALIAN CARABIDiE, iv., 



6.(5)Size small (13*5-15 mm.); elytra with basal border decidedly raised 

 above basal border at humeral angles. 



7.(8)Prothorax not sinuate on sides before basal angles 



85. jV. chalybeus Chaud. 



8.(7)Prothorax lightly sinuate before basal angles 86. JV. hershawi SI. 



84. N. philippi Newm.,( = Percus bipunctatus Cast.).— The 

 species which Castelnau named Feronia (Percus) bipunctata must 

 certainly be considered to be the same as Newman's Feronia philip- 

 pi, but I cannot now accept Chaudoir's view that it is synonymous 

 with F. chalybea Dej., which is a smaller insect. N. philippi is 

 common about Melbourne, and is found generally over the Yarra 

 watershed ; I have found it at Matlock, on the source of the Goul- 

 burn River. Length, 17-21 mm. 



Var. otwayensis SI. — Probably this is a distinct species, but 

 more information than I possess of the spread of N. philippi west- 

 ward from Melbourne, and more knowledge as to any intermediate 

 forms being found, would be necessary before any definite opinion 

 could be ventured upon. 



Var. arcuata, n. var. Differs from N. philippi Newm., by size 

 smaller, prothorax more strongly rounded, more roundly narrowed 

 to base ; basal angles rounded off, not marked ; elytra more obvate, 

 narrower towards base. From N. gravis Chaud., it differs by form 

 less convex, elytra more or less chalybeous, more narrowed to base, 

 basal border obtusely subdentate at humeral angles (a little raised 

 above lateral border). Dimensions: head, 3-2 across eyes; pro- 

 thorax, 3*8x4*6, apex 3*1, base 3*2; elytra, 9*7x5*8; length 

 16 mm. 



Hab. — Werribee Gorge (westward from Melbourne). Colls. 

 Dixon and Sloane. 



I owe it to the kindness of Mr. J. E. Dixon, of Melbourne, that 

 I have been able to examine three specimens of this variety, which 

 he had found at Werribee Gorge. It might be considered a species 

 closely allied to N. philippi, but I prefer to regard it as a variety 

 of that species. 



85. N. chalybeus Dej. — This species is found on King Island. 

 Specimens sent to me by Mr. A. M. Lea, from King Island, agree
