84 NOTES ON AUSTRALIAN COLEOPTERA, 



which is well marked in the Sydney specimens before me, their 

 hind tarsi being very much shorter than those of any BiajjJwro- 

 merus that I have seen, and with the basal joint not longer than 

 the second. The female differs from Ef. inornatus by its straighter 

 hind tibiae and slightly longer hind tarsi. 



Hypharpax obsolktus, sp.nov. 



Brunneus, aeneo- vel subviride-micans, labro mandibulis palpis 

 antennis pedibus scutello et (nonnullis exemplis) marginibus 

 lateralibus flavis ; prothorace fortiter transverso postice 

 quam antice vix latiori, postice utrinque foveolato, foveolis 

 sat perspicue punctulatis, lateribus modice rotundatis, angulis 

 posticis sat rotundatis, latitudine majori mox ante medium 

 posita ; elytris subtiliter striatis, interstitiis planis (postice 

 angustioribus convexis), 3° longe ante apicem (nonnullis 

 exemplis) punctura setifera instructo. 



[Long. 3-3i, lat. l|-li lines. 



Maris tarsis anterioribus 4 minus fortiter dilatatis ; femoribus 

 posticis simplicibus ; tibiis posticis vix arcuatis. 



This species seems very distinct from all previously described. 

 Count Castlenau unfortunately gives no information as to the 

 sexual characters of the numerous Anisodactylides which he 

 described under the name Harpalus, and de Chaudoir has 

 certainly, I think, mixed up Diaphorovierus and Hypharpax in the 

 utmost confusion, so that it is a difficult matter to arrive at 

 absolute certainty, but at any rate there is no species from W. 

 Australia described by either of those authors which seems at all 

 near the present one. Of described species H. Deyrollei, Cast., 

 comes perhaps nearest to it, but in that the hind angles of the 

 prothorax are entirely rounded off (non-existent in fact), whereas 

 in this insect though somewhat rounded at the apex they are quite 

 well-marked, much as in H. inornatus, Germ.
