from the head seemed to indicate the presence of one or two more 

 fine sette. I have therefore refrained from alludino; to the sete 

 of this joint in the diagnosis of the genus, but in any case the 

 affinity of the genus is to those with bisetigerous palpi, its position 

 being apparently between Harplaner and Notophilus.

Hah. — Mount Barker (Lea, three specimens). 



Closely resembling Th. ( Bembidinni) gayatlmhs, Mac!., with 

 which it agrees in facies, sculpture, &c.; but differing by having 

 the metasternum (with its episterna) shorter; the prothorax with 

 the apex less emarginate, the anterior angles less marked, the
