 often associated (whether by accident or intention I know not) 

 with the small black ants which frequent such situations.

This species was discovered under the bark of a dead " Stringy 

 Bark," in the nest of small black ants. The thorax is slightly 

 contracted from the middle towards the base, (but more so in front.) 

 The antenna3 have the club composed of three joints, the middle 

 joint being the broadest, especially in the males, and the last the 

 longest. The carina on the base of the thorax distinguishes this 

 species from all the rest which have hitherto been met with. 



Heteeognathus gracilis. 



Piceo-castaneus ; antennarum articulo 5*° elougato, clava elon- 

 gata ; thorace antice rotundato postice contracto 2-foveolato ; 

 elytrorum humeris rotundatis.

Paramatta, — South Creek, — Brownlow Hill. Under bark of 

 dead trees. 



The club of the antennae is more elongated than in the 

 preceding species, and the joints are narrower, the 10th being 

 hardly wider than the 11th. The 7th and 8th are very small, 

 while the 5th is as long as the 2nd. The species appears to be 

 common .

This species has a very close resemblance to the preceding, of 

 which it is possibly only a variety. It differs principally in being
