DESCRIPTIONS OF NEW SPECIES OF AUSTRALIAN COLEOPTERA. 



Part xvi. 



By Arthur M. Lea, F.E.S. 



By courtesy of the late W. J. Rainbow, I was able to examine some of 

 Maeleay's and Olliff's types, belonging to the Australian Museum, and to make 

 notes on synonymy, as given in some of the following pages. 



STAPH YLINIDAE . 



PiNOPHILUS GRAXDICEPS Maol. 



The type of this species is very close to a specimen in my collection identified 

 as P. trapezus, but its prothorax is less dilated to the apex than on that specimen 

 (this is possibly a sexual difference) . It is very close to P. mastersi (the type 

 of that species has lost its prothorax). but has the suture of the elytra raised (as 

 on trapezus) . 



Philoxthus aexeus Rossi. 



{('nfus amhlijtenis Oil.; Cafius laeiis Oil.) 



The type of C. ambhitenofi agrees perfectly with specimens from New South 

 Wales and Tasmania identified by Blackburn and myself as P. aeneus, and I am 

 convinced belong's to that species ; C. laeus also belongs to' the species, the speci- 

 men from Adelaide (marked as the type) having the three conspicuous punctures 

 (and a smaller apical one) on each side of the middle of the pronotum as on 

 laeus, but in addition there are two irregular punctures on the right row, and 

 one on the left. In comparing amhlyterus and Jaeus, Olliff commented on the 

 difference in the width of prothorax; the sliglit difference, however, appears to 

 be sexual; the punctures at the base of the prothorax (one on each side) are 

 exactly the same, and exactly as on aetieus. 



QuEDius RUFicOLLLS Grav. 



(Philovthtis chah/beipemiis Macl.) 



The type of P. chnli/beipennis is a rather small female of Q. ruficollifi. 



Aleochara puberula Klug. 



(Oxypoda analis Macl.) 



Oxypoda analis has already been referred to Alencliara by Olliff, and from 

 examination of the type I have now to record it as a synonym of the introduced 

 A. puberula.
