abrasion the elytra appear to be finely striated, but after 

 abrasion rows of large punctures become evident. 



Leptops. 



In the table of this genus in Ann. Soc. Ent. Beige, 1916,. 

 a line was unfortunately left out ; this should have followed 

 immediately after K on page 316, as follows: — "KK — Elytra 

 with few tubercles, or if numerous then obtuse." This line 

 governing all the species that followed. 



With long series of many species of the genus one is 

 inevitably forced, to the conclusion that the majority are 

 extremely variable. The sexual differences are usually very 

 pronounced, nevertheless with many species the sexes vary 

 towards each other, so that, from an external observation, it 

 is often difficult to be sure of the sex of an individual. As 

 a natural result, many synonyms have resulted, and the 

 acquisition by the Museum of long series of many species 

 taken by Mr. H. W. Brown in the Cue district has made it 

 possible for some of these to be noted, and the plates given 

 (with the exception of five figures all of the members of the' 

 group w T ith the breast armed, and comprising most of the 

 giants of the genus) will serve to illustrate the great 

 variability in size and sculpture of some of them.

I previously ( 9 ) referred to interioris as a variety of 

 tribulus, and named two other forms as varieties of the same 

 species. But Mr. Arrow, from examination of the type, has 

 pointed out that our identification of trihulus ( 10 ) was incor- 

 rect, and that the real trihulus is the Queensland species 

 known as ferns. 



In Masters' Catalogue, echidna and duponti are given 

 as synonyms of trihulus, but it has been already ( u ) pointed 

 out (from examination of the type) that echidna is really the

(10) The specimens in the late Rev. T. Blackburn's collection 

 identified as tribulus were all of the species commonly supposed to 

 be such, and the numerous references in Australian literature 

 apparently all refer to the same species.
