Australian and Tasmanian Malacodermidae. 83 



irregular double series of punctures ; from most directions (except 

 towards base and apes) appearing uniseriately punctate. Abdomen 

 with penultimate segment triangularly excised to base. 

 Length 11 mm. 



Hah. Tasmania (type in Aug. Simson's collection). 



The figure of Eros jpraefectus, given by Waterhouse,* 

 will give a very good idea of the general appearance of 

 this species, although in that species the elytra are not 

 tipped with red. The antennae are sufficient to distin- 

 guish it from rufipcnnis and all the varieties of that species. 

 The elytra when viewed directly from above appear to be 

 without the fine intermediate ridges (and therefore as 

 uniseriately punctate) but these (or parts of them) are 

 sufficiently distinct from the side. 



Metriorrhynchus gracilis, n. sp. 



(J. Of a sooty -brown colour; prothorax, scutellum, elytra (except 

 an oblique space on each side of apex), coxae, and base of all the 

 femora fiavous. 



Head shining. Eyes large. Rostrum absent. Antennae long, 

 fiabellate ; 2nd joint distinct, 3rd slightly longer than 4th, its 

 ramus (as also that of 10th) about half its total length, 4th-9th each 

 with the ramus distinctly more than half its total length. Prothorax 

 subquadrate, apex produced and rounded in the middle, no narrower 

 than base, anterior angles feebly obtuse, posterior feebly acute, sides 

 feebly constricted in middle, base trisinuate ; 7-areolate, the median 

 areolet small, narrow and confined to basal half, the four front ones 

 very feebly defined ; apical half rather coarsely punctate. Scutellum 

 feebly increasing in width to apex, which is semicircularly emar- 

 ginate. Elytra long thin and parallel-sided ; quadricostate, the in- 

 sterstices with regular (irregular towards apex) rows of rather small, 

 rectangular punctures. Abdomen with penultimate segment widely 

 excised almost to base. 



Length 9 mm. 



Hah. Queensland : Endeavour River (type in Macleay 

 Museum). 



Differs from the description of miniatus in having the 

 apex of the elytra dark and the median prothoracic areolet 

 confined to the basal half, with all of the anterior ones very 

 ill defined ; apparently also in the colour of the legs. It
