rounded and conjointly emarginate at the apex. The fore tibite are 

 less acutely terminated at the external angle than in the other 

 species of the group. The resemblance between this species and 

 A. picipes is very great, 



ArTHROPTERUS OVICOLLIS. 



Long. 6| lin., lat. 2 lin. 



Rufo-piceus subnitidus subhirtus, antennis sublatis articulo 

 primo quadrate, capite post oculos obtuse producto, thorace 

 subovato postice transvei'sim impresso dorso punctato pro- 

 funde canaliculate, elytris leviter punctafcis apice late rotun- 

 datis, tibiis baud latissimis. 

 Hab. South Australia. 

 The comparatively narrow antennre and tibi^ and short hair 

 of this species, are sufficient of themselves to distinguish it from 

 all the others of the Hopei group, while the width and small 

 elongation of the thorax are additional proofs of its aberrant 

 character. It is in fact a near approach to the insects of the 

 second section — A. Wilsoni and others. 



Arthropterus Wyanamatt^. 

 Long. 4| lin., lat. 1| lin. 



Piceo-rufus nitidus crebre punctatus, antennis latissimis arti- 

 culis 2-9 brevissimis, oculis pallidis, thorace quadrate pos- 

 tice subangustato dorso depresso canaliculate ad latera 

 antice rotundato ciliato, scutello transversim pi'ofunde im- 

 presso, elyti'is apice sinuato-truncatis, tibiis posticis extus 

 apice oblique truncatis.

 Two species nearly resembling this insect have been described 

 A. pnrallelocerous, Weston, and WeshvoocUi, MacLeay, W. The 

 first of these, or rather what I take to be it, is a Melbourne in- 

 sect, and is much less densely punctured and more nitid than A. 

 Wyanamattce, the other from Gayndah is of a darker colour, has 

 the basal joint of the antennae more produced at the external 

 angle, has the thorax more narrowed at the base and less densely
