224 NEW SPECIES OF AUSTRALIAN COLEOPTERA, VIII., 



punctate. Legs rather short, tarsi apparently four-jointed. 

 Length 4| mm. 



Hab— Sydney, N.S.W. (A. M. Lea). 



This genus is abundantly represented in Tropical America, and 

 a few species have been recorded from Burmah, &c. ; but it has 

 not hitherto been recorded from Australia. It can be readily 

 recognised by the terminal joints of the antennae. In the only 

 specimen I have seen it is difficult to see the 6th-8th joints at all 

 clearly, as they are not only very short and closely joined together, 

 but are partly obscured by pubescence. 



Family PTINID.^. 



Trigonogenius globulus Sol. 



This species occurs in houses in Tasmania and Western Aus- 

 tralia ; it was originally described from South America, and has 

 also been taken in England. I am indebted to Mr. Champion 

 for the name. 



Niptus hololeucus Feld. 



This species also occurs in Tasmania, as Hobart specimens 

 agree exactly with two sent to me under this name by Mr. 

 Champion. 



Hexaplocotes, n.g. 



Antennae very stout, six-jointed, the two terminal joints form- 

 ing an almost circular club. Other characters as in Polyplocotes. 



This genus belongs to the section of the Ptinidce which includes 

 Diplocotes, Polyplocotes, Diphobia and Paussoptinus, from all of 

 which its six-jointed antennae will readily distinguish it. For 

 purposes of classification it may be placed after Polyplocotes. 

 The type and only specimen I have seen was taken in the nest 

 of an ant under a stone. 



Hexaplocotes sulcifrons, n.sp. 



(Plate xviii., fig.8.) 



Dark reddish-brown; club, legs and abdomen somewhat paler. 

 Clothed with a thin yellowish pubescence.
