416 REVISION OF THE AUSTRALIAN CURCULIONID.E, VIII,, 



ately stout, not grooved, dentate, posterior not extending to apex 

 of abdomen; tibiae short, compressed, the anterior bisinuate 

 beneath; tarsi rather short, 3rd joint wide and deeply bilobed, 

 4th elongate. Elliptic, convex, squamose, non-tuberculate, 

 winged. 



Allied to the preceding genus, which it resembles in the long 

 rostrum and exposed intermediate coxae, but distinguished from 

 it by the absence of a prosternal process between the four anterior 

 coxse. In tanyrhynchus the canal extends almost to the abdomen 

 but it is entirely different in character from that of Myrtesis. 

 The genus appears to be abundantly represented in the Malay 

 Archipelago, but only one species has previously been recorded 

 from Australia. 



Pectoral canal terminated almost at abdomen tanyrhynchus. 



Pectoral canal terminated just behind intermediate coxae... mixtus. 



Berosiris mixtus, n.sp. 



Elongate-elliptic. Reddish-brown, antennee paler. Densely 

 clothed with fawn-coloured scales somewhat variable in shade, 

 and with patches of sooty scales; scutellum nude. Under surface 

 with rather pale scales except at sides and on the apical segments. 

 Head and basal third of rostrum in (J, basal fourth in 9, with 

 dense and rather dark scales. 



Head with dense, round, concealed punctures. Rostrum thin, 

 longer than prothorax and scutellum combined; in ^ basal half 

 with coarse concealed punctures, the apical half shining; in 9 

 basal fourth only with rather coarse punctures. Scape inserted 

 one-third from apex of rostrum in $ (two-fifths in 5); 2nd joint 

 of funicle as long as the 3rd and ith combined, 1st and 3rd sub- 

 equal. Prothorao: moderately transverse, apex produced and less 

 than half the width of ba.se; with dense, round, concealed punc- 

 tures. Scutellum oblong and shining. Elytra slightly wider 

 than prothorax and about twice and one-half its length: with 

 series of large, deep, oblong, more or less concealed punctures; 

 interstices apparently much wider than punctures but really 

 considerably narrower except posteriorly, the alternate ones very
