194 MEMOIL'S OF THE QUEENSLAND MUSEUM. 



sixth and seventh segments of the abdomen, or sometimes only the sixth, have a 

 small waxy- white strip on eaeh side. The rostrum is more than half the length 

 of the prothorax and its upper surface is about twice as long as wide, but the 

 lower surface is dilated at the base. In my table would be placed with 

 M. lateralis, from which they differ in being larger and in having the rostrum 

 and antennte decidedly shorter. 



Var. — Four specimens from New South Wales (Dorrigo, W. Heron ; and 

 Illawarra, II. W. Cox) have the elytra black, with the sides, apex, and suture 

 pale ; the pale parts are somewhat dilated on the shoulders, and continued for a 

 short distance along some of the costa; ; about one-fourth or one-fifth of the tips 

 are pale. The size ranges 10-17 mm. and the under parts are as on the typical 

 form. In my table the variety would be associated with 31. vuriipennis, from 

 .which it differs structurally as the types. 



METRIORRHYNCHUS DENTIPES sp. nov. 

 $ Black and flavous, inclining to brick-red. 



Head with rostrum of moderate length (about as long as its basal width). 

 Antenna? rather long, most of the joints strongly serrated, second minute, third 

 to fifth with some long straggling hairs on under surface, third about twice as 

 long as wide, its tip slightly produced on one side of apex, fourth distinctly 

 shorter than third, and scarcely longer than fifth, their tips more distinctly 

 produced than on third, sixth to tenth with serrations commencing at base. 

 Prothorax along middle about as long as greatest width, conspicuously seven- 

 areolate ; apex subtriangularly produced in middle, sides subparallel to middle, 

 then dilated to base, hind angles subacute. Elytra with regular double rows of 

 punctures, the alternate interstices elevated. Tibke wide, the hind ones each 

 with a large obtuse tooth about one-third from apex, and a large truncated 

 process on the inner side. Length { $^ ), 8-10 mm. 



9 Differs in having antenna? with shorter and less stronglj^ serrated 

 joints, the subbasal ones without special clothing, abdomen not notched, and 

 hind tibia? unarmed.

The pale parts are the prothorax, scutellum, elytra (except from about 

 one-fourth to about one-seventh of the tips), parts of front and of middle legs 

 (on some specimens the only parts of these that are dark are the tarsi, on others 

 the tibiae and part of the femora are dark, on some more of the middle than of 

 the front legs are dark), and parts of under surface of from three to five basal 

 joints of antennae; on three males and two females most of the head is pale, on 

 saven other males it is entirely dark. The rostrum is the exact length of that 

 of M. rufirostris, noted in my table as of "moderate" length, but the female 

 differs from the female of that species (the only sex at present known) in having 

 the elytra tipped with black, and more of the legs pale ; regarding the rostrum
