It should be furtlier noted that the elytra of the typical 

 Automoli have a characteristic outline. Their lateral margin 

 is more or less strongly sinuate, and they are narrowed be- 

 hind in such fashion that outside a short apical portion of 

 them the surface of the abdomen is to a s^reater or less extent 

 visible on either side. In Ccndohius villi f/er, and in the other 

 species that I now attribute to Cavlohins, the lateral margins 

 of the elytra are straight, or almost straight, and the elytra 

 are not narrowed hindward : but one which T attributed for- 

 merly to Cauhihhis, and which I now transfer to Automolus 

 on account of its exposed prop3'gidium [.1. (Cavlohhi^) evane- 

 scens'], has elytra intermediate in form between those of a 

 typical A'Utomolus and of (■(inlohius viUiper. 



It appears to me quite possible that when both sexes are 

 known of all the species which I now place in Automolus and 

 Ca 7(1 oh ins it may be found necessary to form, for species tliat 

 do not appear quite at home in either of those genera, at least 

 one new genus. Meanwhile, the tabulation given above will 

 enable the student to assign without hesitation any of them 

 to the genus in which I should place it. 



Hitherto only the typical species {angystulus, Burm.) has 

 been referred to Aufomoliis, but 17 other names, which appear 

 to me clearly referable to this genus, have been given to 

 species that have been attributed by their authors to Liparr- 

 triis or Caul oh ins. Three of these names, however, I believe 

 to be synonyms, viz., Automohis (Liparetrus) hasaJis, Mad. 

 (nee. 'B]anch.) = hi color : Blackb.. Automolus (Liparefrvs ) 

 Cooki ; lsla.c\. = depressus, Blanch., Automolus (Liparetriis) uni- 

 color, Macl. = humilis, Blanch., female. I regard it as barely 

 possible that also Automolus (Liparrtrus) alpicola, Blackb. = 

 angustulus, Burm. This synonymy will be found more fully 

 discussed below. I therefore regard Automolus as consisting 

 of 15 species, already described, and to these I have now to 

 add 6 new species, bringing the number of Australian 

 Automoli up to 21, all of which I believe that I know, except 

 angustulus, Burm. 



The following is a tabulation of the distinctive characters 

 of the species that I place in the genus Automolus : — 



A. Lateral part of elytra vertical, its 



limits defined both above and below. 



Anteniial clnb fonr-jointed in both 



sexes, so far as known. 



B. Pilosity of elytra as Ions: a'^ of pro- 



notum hispidus. Mad. 



BB.. Pilosity of elytra much shorter ... aureus. Blackh. 

 AA. Lateral part of elytra not as in A. 

 Antennal clnb. so far as known, only 

 three-jointed in both sexes.
