440 REVISIONAL NOTES ON AUSTRALIAN CARABID^E, iv., 



Hob. —Queensland : Herberton District (F. P. Dodd). Coll. 

 Sloane. 



An isolated species, at once differentiated from all others by- 

 having the pronotum opaque and transversely striolate, and the 

 posterior marginal seta on the border at basal angle. 



72. N. dyscoloides Motsch.,[ = N. sphodroides SI., (1902), not 

 Dejean]. — A variable species in colour, size, and convexity of 

 elytral interstices, also in the number of punctures on the third 

 interstice; usually there are three or four of these punctures, but 

 small specimens, from Marysville and the Baw Baw Mountains, 

 have only two punctures; the elytra are generally longitudinally 

 depressed along the course of the third interstice. The intermedi- 

 ate tarsi have the external costa of the first joint spinulose be- 

 neath, but the posterior tarsi have no spinule beneath the costa. It 

 has not much affinity with any other species of the group in which 

 I have placed it. The species most nearly allied to it seems to be 

 A T . victoriensis SI. Specimens with violaceous elytra occurred to 

 me at Warburton and Marysville ; doubtless these represent Ptero- 

 stichus semiviolaceus Cast. Length, 12-7-15 mm. Specimens from 

 the Dandelion g Ganges have the elytra more cyaneous, and are 

 evidently the form which Castelnau distinguished under the sepa- 

 rate name of Pterostichus victoi'ice; this is the form I erroneously 

 thought to be N. sphodroides Dej., in 1902; the material now 

 before me indicates that this slightly differentiated form is not 

 worthy of a varietal name. Length, 13-15 mm. Specimens from 

 Marysville are smaller, and have the elytra with only two punc- 

 tures on the third interstice. Three specimens are before me, taken 

 near Keppel's Falls, on the Taggerty River; two of these (<J$) 

 have the elytra cyaneous, the other (£) violaceous. It seems a 

 variety. Length, 12-12-5 mm. 



Var. simulans Chaud. — I have specimens from Victoria which 

 differ from N. dyscoloides Motsch., by colour, in the same way that 

 N. simulans is said to do ; namely, elytra cupreous, with the border 

 black. (It may be noted that N. dyscoloides has the border of the 

 elytra black). I look upon my specimens as representing a variety 

 of N. dyscoloides, rather than a distinct species. Length, 15 mm.
