436 REVISIONAL NOTES ON AUSTRALIAN CARABID^E, 



the insertion of the trochanter; this may be called the discal seta; 

 the other is on the side of the coxa, below and forward from the 

 insertion of the trochanter; this may be calletl the lateral seta. 

 Sometimes corresponding tactile setse may be found on the 

 SiVitQviov coxsd{Q.g., Secatophus, Teropha, Paranuriis, Ceratoferonia, 

 Loxodactyhis, JVotononius, etc.). Both the anterior and inter- 

 mediate coxse may have, besides the tactile setae, their surface 

 more or less pubescent {e.g., Chlseniini), and frequently several 

 lateral tactile setae are found on the intermediate coxae. 



Tribe Chlseniini- 



BiuUe, Hist. Nat. Ins. 1834. 



Head with one supraorbital puncture on each side; mandibles 

 without setigerous puncture in external sciobe. Prothorax with 

 posterior socket-hole usually fringed with hair above peduncle; 

 a marginal seta at, or near, each basal angle. Body not pedun- 

 culate; scutellum dividing elytra at base. Elytra bordered at 

 base, striate, setulose at least towards sides and apex; margin 

 interrupted posteriorly and with a distinct internal plica; ninth 

 interstice variable in width, never linear, or situated in a furrow, 

 or below plane of eightli. Mesosternum with intercoxal declivity 

 deeply excavated; intercoxal parts of prosternum and meso- 

 sternum, anterior and middle coxEe setose. Posterior coxse not 

 raised abruptly from first ventral segment; tarsi with fiftli joint 

 setulose beneath. 



The tribe, as represented in Australia, contains two genera, 

 which may be differentiated thus : — 



Head shagreened, not punctate; pronotum with only a few minute punc- 

 tures; prosternum impunctate before coxae: penultimate joint of labial 

 palpi without setfe Hololeius. 



Head more or less punctate; pronotum coarsely punctate; prosternum punc- 

 tate before coxae; penultimate joint of labial palpi with several setse on 

 anterior margin in all Australian species Chl.enius. 



Genus Hololeius.
