This is probably the most widely distributed and at the 

 same time the most variable species in the subfamily. I 

 have specimens from all the Australian States. Not only 

 are the colours and markings very variable, but the sculp- 

 ture of the elytra is much less acute in some specimens 

 (especially in the varieties about flavocinctus) than in 

 others ; the prothorax also seems to overhang the head 

 more in Jlavocinctus and amplicollis than in the more 

 typical forms. 



On Mt. Kosciusko and in Tasmania a variety occurs which 

 is entirely black except that parts of the coxae and some of 

 the antennal joints are obscurely diluted with red. In 

 specimens havmg the ordinary markings the black terminal 

 joints of the antennse vary in number from one to seven. 



A small male from Brisbane agrees exactly with 

 Chapuis' description of amplicollis (a variety close to flavo- 

 cinctus); a female received with it has the prothoracic 

 cross reduced to a longitudinal and two transverse dis- 

 connected vittae. 



Of cinnamomcus Blackburn says (T. R. S. S. A., 1890, p. 

 136) : " I have never seen a specimen quite agreeing with 

 Sutfrian's type, which should have no markings at all on 

 the prothorax." I have a pair taken near Sydney in cop., 

 of which the female has the prothorax entirely without 

 markings and agreeing with Suffrian's description of 

 cinnamovicus, and the male with the markings ascribed by 

 Saunders to flavocinctus. 



I have not considered it necessary to give any fresh 

 varietal names, although the black specimens from Mt. 

 Kosciusko and Tasmania are much more distinct from the 

 typical form than any of the already named varieties.
