40 ON THE PSELAPHIDiE OF AUSTRALIA, 



gTass land between a newly cultivated field and the bush ; 

 a number of thorny bushes (Bui'saria spinosa) afiford a little 

 shade. I describe the place with this minuteness, because 

 from the same small locality I obtained a large number both of 

 species and individuals of Pselaphidaa, besides many other 

 interesting Coleoptera.

 The antennse are of the ordinary form, the last three joints 

 forming a moderate club.

 The club of the antenna) is formed of the four last joints, 

 which are elongated in shape.

Lane Cove, from the collection of W. MacLeay, Esq. 

 Of this very distinct species I have only seen a single speci- 

 men. It comes nearer to T. carinatus (Say) than the two pre- 

 ceding species. It is readily distinguished from them by its 

 greater size, the bicarinations on the abdomen, the convexity of 

 the thorax, and the club of the antennre being composed of three 

 joints, the middle being the shortest of the three.
