the Australian Curculionidfe. 87 



ACHEREES. 

 Caput antice convexum, rotimdatum ; rostrum validum, breve, ver- 

 sus apicem gradatim crassius, basi transversim sulcatum, bialatum, 

 ala utrinque supra oeulum currente ; scrohes breves, laterales, 

 parum arcuatas. Oculi parvi, rotundati, a prothorace distantes. 

 Antenncv breviusculae, clava distincta. Prothorax breviter ovatus, 

 apice truncatus, lobis ocularibus nullis. Elytra ovalia, basi pro- 

 thorace baud latiora, utrinque antrorsum paulo producta, postice 

 declivia, plica epipleurali ad apicem instructa. Pedes subvalidi, 

 setosi ; femora paulo iucrassata ; tihioi rectse ; tarsi robusti ; arti- 

 culis tribus basalibus triangularibus, ultimo baud bilobo, postice 

 paiilo longiores. Abdomen segmentis marginibus prominulis, 3-4 

 conjunctim secundo lougioribus. 



The essential characters of this genus lie in the absence of 

 the ocular lobes and in the form of the rostrum. The claw- 

 joint is received in a cavity of the preceding one, and the 

 three basal are all prolonged beneath into a sort of spine. 

 This structure is common to most genera of the subfamily, 

 and more or less to the Brachycerinte, Byrsopinaj, &c.

 medio prothorace fere duplo latioribus, grosse seriatim punc- 

 tatis, dorso mamillis nonnullis depressis, aliis externe tuberculi- 

 formibus, quarum duabus posticis majoribus, instructis, his punctis 

 plurimis, illis punctis 1-3 impressis, punctis generaliter setigeris ;

Ennothus. 



Acherre differt rostro bicornuto, jjlica epipleurali elytrorum nulla, 

 et tarsis articulo ultimo bilobo. 



In Acherres the base of the rostrum is prolonged into two 

 wing-shaped bodies extending above and overlapping the eyes 

 on each side ; in this genus it is nearly the same as in Odi- 

 tesus 5 but in the absence of ocular lobes and in habit it agrees 

 with the former genus.
