joints of the antennae, but later (when tabulating the genus) 

 the species was placed in a nine- jointed group. Owing to 

 the close approximation of the joints between the second and 

 club, I could not count these clearly with a Coddington lens, 

 but under a compound power it was seen that there were nine 

 joints, of which the fifth and sixth were very closely applied 

 to the club; the upper tooth of the front tibiae is very small, 

 and on i'ome specimens almost approaches obliteration. 



LlPARETRUS IMPRESSICOLLIS, Mad. 



Three specimens, from Sydney and Galston (New South 

 Wales) differ from the typical form of this species in having 

 the elytra of a brighter red, the propygidium, pygidium, and 

 three apical segments of abdomen are also red ; their pygidium 

 has an irregular median carina, that is scarcely traceable on 

 the typical form. 



Liparetrus discipennis, Guer. 

 Two specimens from Stanthorpe (Queensland) differ from 

 the normal form of this species in having the prothorax and 

 elytra somewhat shining, and with much more conspicuous 

 punctures; but as they exactly fit into the position assigned 

 to the species in Blackburn's table, and in other respects 

 agree with normal specimens, I presume they represent but 

 a variety. 



Liparetrus ferrugineus, Blanch. 



A male before me has the clothing of the pronotum 

 confined to conspicuous fringes at the sides and apex, but 

 otherwise agrees with normal males; four females are entirely 

 without the apical fringe (they are in good condition and do 

 not appear to be abraded), and its absence would therefore 

 cause them (in Blackburn's table) to be referred to Group 16 

 (instead of to Group 15). 



Liparetrus fallax, Blackb. 



I can see no difference whatever in the hind angles of the 

 prothorax of the type of fallax and specimens identified by 

 Mr. Blackburn as atriceps, but those of the former were 

 tabulated as "quite defined" and of the latter as "rounded 

 off (non-existent)." Looking at them at right angles they 

 are seen to be rounded off, but from some directions 

 (especially if a few hairs are in the way) they appear to be 

 obtusely angular.
