156 Mr. Arthur M. Lea's Revision of the 



strongly concave (the inside portion pallid) 2nd * joint 

 of antennae and dark apex of elytra,j" and agrees exactly 

 with Blackburn's description of fcmoralis. In the species 

 the elytral fascia varies considerably in width ; on 

 specimens from Queensland and the western parts of New 

 South Wales, being, as a rule, larger than on specimens 

 from Victoria and Tasmania. 



Fairmaire gives mastcrsi as a synonym of einctiLS,\ and I 

 previously (apparently not on good grounds) doubted this. 

 Blackburn appeared to regard femoralis as distinct from 

 ductus partly on account of colour and partly on account 

 of the shape of the prothorax ; but the dark portions of the 

 elytra in most species of Lams, and certainly in the present 

 one, are subject to considerable variation, and, as above 

 noted, the fascia is of variable width. Blackburn admitted 

 not knowing the male of cinctus, of which Redtenbacher 

 says of the prothorax "gegen das Schildchen etwas 

 erweitert."

The original description of this species is so worthless 

 that I think it should be regarded as non-existent, at any 

 rate until the type can be examined and further informa- 

 tion obtained about it ; the description is simply a short 

 comparison with hellulus, and may have been drawn up 

 from a variety of that species. In any case Fairmaire's 

 name must fall, as the name was preoccupied by W. S. 

 Macleay's Malachius verticalis, which, as noted above, is a 

 true Zaiits.

* Herr Redtenbacher correctly describes the 2nd joint as being 

 quite in the top of the first, and the 3rd as much longer and thicker 

 than the 4th ; but I think it convenient to regard the true 2nd joint 

 as non-existent ; as in most species of Lams it is either traceable 

 with extreme difficulty or quite invisible.
