upper part of the propygidium, and also of the pygidium, 

 has squamiform setae on some of the specimens, but they 

 appear to be easily abraded, as others have those parts quite 

 glabrous; hence their position in Group 4 depends on their 

 state of preservation ; in good condition they would be 

 referred to H, II, to no species of which do they look at all 

 close ; but with the hind parts abraded they would be referred 

 to HH, II, and there associated with juvenis. The punctures 

 on the head are not confluent, but I cannot regard them as 

 sparse, either on the types or on the Daly River specimens. 



LlPARETRTJS NIGROUMBRATTJS, Blackb. 



This species occurs in New South Wales, Victoria, Tas- 

 mania, and Flinders Island, as well as in South Australia. In 

 the original description all that was said of the clothing of 

 the hind parts was "pygidio propygidioque longe fulvo- 

 pilosis, ,> but it is rather peculiar (there are a co-type and 

 other specimens named by Blackburn in the Museum) on 

 specimens in good condition it is almost white, and consists of 

 long straggling hairs, and rather dense pubescence (scarcely 

 setae), rather closely applied to the derm; on some specimens 

 there appears to be even a third kind of clothing : rather 

 short setae at right angles to the derm (but possibly these 

 are remnants of broken hairs). In the table the species was 

 placed in Group 5, but the basal joint of the hind tarsi (when 

 the full length of each is visible) is seen to be distinctly 

 longer than the second. The colour variety, described from 

 Kangaroo Island, is equally as common as the typical form, 

 and on a rare variety the elytra are much darker (almost 

 piceous-brown). 



LlPARETRTJS SERICEUS, Mad. 



On this beautiful species (fairly common in the southern 

 parts of Queensland) the pygidium and propygidium are 

 occasionally reddish. 



Liparetrus iridipennis, Germ. 



On some females of iridipennis the elytra (except for a 

 basal infuscation) are obscurely reddish; the lateral fringe 

 of the pronotum was tabled by Blackburn as •'whitish," it is 

 often whitish at the base, but usually becomes considerably 

 darker in front. 



Liparetrus ttjberctjlatus, Lea. 



In Blackburn's revision the statement was made that 

 this species was practically undescribed, and it was assumed 

 that my reference of it to Macleay's Sec. 1, Sub-sec. 3, c,
