some directions, but when viewed directly from behind 

 appears quite as black as the rest of the elytral clothing. 



The two species here described, and amoemis, Mjob., all 

 belong to 



11 a. Appendages black or almost so," 



of my previous table ( ? ) and with the species of a may now be 



tabled : — 



* Elytra more or less bluish. 



t Elytra with conspicuous snowy markings ... albomaculatus 



ft Elytra without such caeruleipennis 



** Elytra not bluish. 



b. Elytra with pale clothing on apical portion 



of suture adeps 



bb. Elytra without pale clothing there. 



c. Each elytron with a single spot of snowy 



scales niveonotatus 



cc. Each with more than a single spot of 

 snowy scales. 

 If Third interstice with a snowy spot at 



basal third amoenus 



UK Without a snowy spot there leucomelas 



Mezium sulcatum, Fabr. 



Mr. Champion identified some specimens from Western 

 Australia that I sent to him as belonging to this species, which 

 occurs also in South Australia and New South Wales, but does 

 not appear to have been previously recorded from Australia. 



Mezium affine, Boield. 



Numerous specimens from South Australia agree well 

 with British specimens of this species. 



Mezium, sp. 



A third species (no doubt introduced) also occurs in 

 Australia. In size it is intermediate between the two pre- 

 ceding species, and differs from them also in having numerous 

 stout setae scattered over the elytra from base to apex. 



Hab. — South Australia: Coulta; Western Australia: 

 Geraldton, Swan River. 



Diplocotes foveicollis, Oil. 



Two specimens taken by Messrs. B. A. Feuerheerdt and 

 F. Seeker, in ants' nests at Lucindale, differ from specimens 

 agreeing with the type of this species in being larger (2f-3 

 mm.), with the joints of the antennae stouter, and the elytra 

 practically glabrous.
