538 REVISION OF THE AUSTRALIAN CURCULIONID^, 



Under surface irregularly and in places rather densely punctate; 

 metasternal episterna each with a single row of punctures. 

 Length 8|, rostrum If; width 3^; variation in length 7|-8| mm. 



Hah.—(^. : Mount Dryander (Mr. A. Simson, No. 2229). 



With a good lens and in suitable lights the whole of the under 

 surface may be seen to be densely covered with very minute 

 punctures, 



Therebiosoma, n.g. 



Eyes finely faceted. Rostrum feebly curved. Two basal joints 

 of funide equal in size; club normally ovate. Prothorax decidedly 

 transverse. Pectoral canal I'ather narrow and deep, terminated 

 almost at metasternum. Mesosternal receptacle quadrate, sides 

 very narrow; open. Femora edentate. Other characters as in 

 the preceding genus. 



Allied to the preceding genus and to Therehus, from both of 

 which it may be readil}"- distinguished by the shape of the meso- 

 sternal receptacle. 



Therebiosoma rhinarioides, n.sp. 



Dull reddish-brown, rostrum darker; antennpe and tarsi reddish. 

 Moderately densely clothed with dingy ochreous scales, the elytra 

 Avith a feebly maculate appearance owing to spots of sooty scales. 

 Under surface and legs more regularly clothed with paler scales. 

 Head and basal third of rostrum squamose. 



Head densely but indistinctly punctate. Rostrum densely 

 punctate on basal third, elsewhere shining and with small but 

 deep and distinct punctures; from base to near antennie a feeble 

 groove; on each side from just behind antenn;e to apex a shining 

 impunctate median space. Prothorax with dense, round, clearly 

 ■cut punctures, which, however, are partially obscured by scales; 

 a small shining carina continuous from base to apex, close to 

 which the punctures are smaller and slightly compressed. Elytra 

 striate-punctate; punctures deep, oblong, and each containing a 

 scale; interstices much wider than striae and densely punctate.
