Hcib. Tasmania: Bruni Island {A. M. Lea), Hobart 

 {H. J. Carter). 



A male from the Huon River has the 3rd joint longer 

 than the type, with its ramus shorter and nearer the 

 parallel to the joint itself. A similar variation is common 

 in rhipidius. In fact, practically the only really distinct 

 feature separating this species and rhipidius is the colour 

 of the elytra. 



From the other black Tasmanian species it can be dis- 

 tinguished by the length of its rostrum (as against atratus), 

 and by the double series of punctures on the elytra (as 

 against insignipiennis). It would be a Porrostoma according 

 to Mr. Waterhouse. The specimens from Bruni Island 

 were taken on Lcptospcrmuvi blossoms. 



Metriorrhynchus disconiger, n. sp. {Fig. 160.) 



(J . Black ; elytra partly reddisli-testaceous. 



Head moderately shining. Rostrum long (about twice the length 

 of basal joint of antennae), but fairly stout. Antennae extending to 

 middle of elytra, pectinate ; 2nd joint indistinct, 3rd distinctly longer 

 than 4th, its ramus not half its total length, 4th-8th each with the 

 ramus half the total length, of 9th shorter, of 10th still shorter. 

 Prothorax feebly transverse, apex rounded, sides feebly constricted in 

 middle, posterior angles subacute ; distinctly 7-areolate. Sc\dellum, 

 rather feebly emarginate at apex. Elytra rather less narrow than 

 usual ; quadricostate, the interstices with irregular double rows of 

 punctures, becoming more regular and almost rectangular towards 

 base. 



Length 11 mm. 



9 . Differs in being larger, prothorax and elytra rather wider, 

 antennae shorter, strongly serrate only, and with the 4th-9th joints 

 transverse.

 C. French's collection). 



The black portion of the elytra is narrowest at the base, 

 gradually dilated towards and widest at a little beyond the 

 middle, and then contracted and terminated (with a rounded 

 outline) at about one-seventh from the apex in the male, 

 at about one-sixth in the female ; at its widest it almost
