Australian am<l Tasmanian Coleoptera. 171 



distinct. Ahdarnfii with ba.siil fovea large and eneroachinir in 

 the form of a wide triangle on to middle of second segment, 

 each side of base with a wide flat feebly elevated oblique ridge. 

 Metasternum gently convex in middle. Femora moderately 

 stout; tibiae inflated towards apex. Length 1^ mm. 



Hah. — S. Australia (type in Macleay Museum). 



The abdominal fovea is of very different shape to that of 

 the species I suppose to be hreripefi, and the metasternum, 

 although shining, is not highly polished along the middle as 

 in that species ; the antennae also are different. In size and 

 general appearance, however, the two species are very similar. 

 The antennae and abdominal fovea are somewhat as in diJati- 

 cor)ii<. but that species is described and figured as having the 

 prothorax longer than wide. The antennae, both from above 

 and the sides, have the outlines as in dentipes, but are dis- 

 tinctly impressed in the middle. One of the specimens was 

 labelled as setipes, but it dift'ers from the description of that 

 species in having a distinct sutural stria, and the tibiae without 

 long setae towards the apex ; the latter character may be sexual 

 but not the former. Its abdominal fovea also is not as figured 

 in setipes. 



Art/reriis roiistrirtiro/->us, n.sp. (Figs. 38, 39.) 



2 • Dark reddish castaneous, greater portion of each elytron 

 somewhat paler. Clothed with short, depressed setae, except 

 on abdomen where they are sparser and more erect, each side 

 of base also with a thin elongated ridge or depressed fascicle, 

 middle of metasternum with a line, of golden setae. 



Head (for the genus) rather long, flat, densely punctate, and 

 without median impression. Antennae moderately wide, some- 

 what curved, the length of, or slightly longer than, head. Fro- 

 th ora 7; widest near apex, where the width is about once and 

 one-half the length, sides gently but distinctly decreasing to 

 base ; medio-basal impression lather small and feeble ; punc- 

 tures as on head. Elytra with dense punctures, becoming 

 sparser at inner disc; svitural stria distinct. Abdomen with 

 basal fovea strongly transverse and deep, near each side with 

 a wide very feebly elevated oblique ridge, sides with margins
