Leptops amplipennis, Lea. 

 PI. xxxv., fig. 90. 



The figure given is that cf the only specimen I have seen 

 of this species. 



Leptops muricatus, Pasc. 

 PI. xxxv., figs. 91 and 92. 



In the genus Leptops there are very few species that 

 closely resemble each other and yet may be distinguished by 

 strong differential characters ; but there are two species before 

 me either of which might be muricatus by the description, 

 which strongly resemble each other and yet are certainly 

 distinct. One of these is described as new under the name of 

 browni, the other I previously tabulated as muricatus; the- 

 latter has a small but distinct Catasarcus -like tubercle on each 

 elytron, the median carina of the rostrum is not abruptly 

 terminated, but vanishes level with the parts about the base 

 of the rostrum, and behind it there is a shallow groove, quite 

 disconnected with the grooves on each side of the median 

 carina, characters strongly at variance' with browni; there is a 

 feeble and very obtuse swelling in front of each front coxa, 

 but this is very different to the conspicuous conical or sub- 

 conical tubercle of broumi. As it is a widely-distributed 

 species, and occurs on the coast of Western Australia (the 

 type was from Nicol Bay), it is much more likely to be the 

 true muricatus than browni, which so far has only been taken 

 in the dry interior by Mr. Brown 



Leptops duboulayi, Pasc. 

 PI. xxxix., figs. 151 to 153. 

 A very fine species, varying in some directions towards 

 colossus, and in others towards hercules, but quite distinct 

 from both. 



Leptops horni, Blackb. 



Two specimens from Derby may represent a variety of 

 this species; they differ from the description and from some 

 typical specimens in being much larger (15-18 mm.), with 

 one pair only of conjoined tubercles on the suture, and that 

 pair comparatively smaller, the median groove of the pro- 

 thorax is also more pronounced and regular. 



Leptops palmensis. Blackb. 



In the 1906 table of the genus a co-type ( 1? ) of this species 

 would be asociated with horni, from which it differs in the
