Australian and Tusmnniitn Coleopfera. 149 



larger (2 2-3 mm.), shoulders more obtusely dentate, metas- 

 ternum flattened and trochanters unarmed. 



liafrisodf-x nohilis, King. 



A single badly danuiged male before me probably belongs to 

 this species. It was taken at Galston from the nest of a white 

 ant in the " pipe " of an " ironbark " eucalyptus tree. The type 

 of iiobilis was also from a white ants" nest at Parramatta (quite 

 close to Galston), but King considered it was there by accident. 



The head of the Galston specimen is much as in Raffray's 

 figure of tirsinus,^ except that it has no basal carina. Each of 

 its hind trochanters is armed with a small, acute, curved spine. 



Batrisiis aiiyalatus, Westw. 



Recorded originally as from ants' nests. Tlie species is 

 omitted from Raffray's recent monograph in Wytsman's Genera 

 Insectorum. As the genus Batrisus is now defined, angulatus 

 certainly cannot belong to it, as the abdomen is figured as being 

 decidedly margined. 



Batraxis armitagei. King. 



Mr. Cox has taken single specimens of this species from nests 

 of Ponera httea and Ectatomina metallicuni, near Sydney. 



The species was referred to Bryaxis by King, to Bafristin by 

 Schaufuss, and to Bafran's by Raff ray. 



Bdfraris laevif/ata, Rafi'r. 



The specimens described by M. Raffray were taken from a 

 nest of C'amponotus ofUfopihii^us.

<?. Blackish brown, elytra dark reddish-brown ; legs pale 

 castaneous, fifth and ninth to eleventh joints of antennae 

 darker. Upper surface with conspicuous and rather long pale 

 hairs.
