442 REVISIONAL NOTES ON AUSTRALIAN CARABID.E, 



peduncle; lateral margins normally without setsefonly in 0. 

 oblongus, and 0. inornatus Cast., have I found a marginal seta 

 near each basal angle). Body not pedunculate; scutellum divid- 

 ing elytra at base. Elytra bordered at base, striate, glabrous; 

 margin interrupted posteriorly and with a distinct internal plica; 

 ninth interstice linear, and placed in a marginal furrow. Meso- 

 sternum with intercoxal part deeply excavated; intercoxal part 

 of prosternum and mesosternum, and anterior and middle coxfe 

 not pubescent. Middle coxse bisetose; posterior coxse not 

 raised abruptly from first ventral segment; tarsi with fifth joint 

 glabrous beneath 



According to Chaudoir's classification, the Australian fauna 

 contains three genera of Oodini; and though the differences 

 which distinguish these three genera seem to me hardly of full 

 generic importance, yet, seeing that often there must be varying 

 opinions on the status of such groups, it has seemed best to 

 recognise Chaudoir's views on the subject, rather than to reduce 

 Anatrichis and Coptocarpus to subgenera of Oodes. I tabulate 

 our genera thus : — 



Clypeus without setigerous punctures. (Labrum with anterior margin tri- 

 foveolate, the median fovea with two or four fine sette. In male, anterior 

 tarsi with two basal joints Hghtly dilatate and squamose beneath, tliird 

 and fourth joints smaller, subequal in width) Anatkichis, 



Clypeus bisetigerous. 



Elytra with first stria lightly deflexed considerably behind scutellum, and 

 reaching puncture at base of second stria; scutellar striole elongate 

 (rarely obsolete or obsolescent). Prosternum with intercoxal part usually 

 not bordered (bordered in O. latus Cast., 0. inornaUis Cast., and 0. 

 jyarvictps SI.). Fourth and fifth ventral segments bisetigerous. In 

 male, three basal joints of anterior tarsi dilatate and spongiose beneath, 

 fourth joint attached to third in middle Oodes. 



Elytra with first stria parallel with suture to, or almost to, its basal 

 extremity, not attaining puncture at base of second stria. Scutellar 

 striole obsolete, or very short. Prosternum with intercoxal part 

 bordered. Fourth and fifth ventral segments without ambulatorial 

 setas. In male, three basal joints of anterior tarsi very widely dilatate 

 and spongiose beneath, fourth joint small, narrow, attached to third 

 near innerside Coptocakpus.
