I liave not yet succeeded in detecting this species, except in 

 the one very limited locality, near Paramatta. The figure in 

 Plate V. is very imperfect in its proportions. 



Genus II. Ctenistes. Heichenb. 



Sp. 2. 0. vernalis. 



The male of this species was described in Part I., p. 40, as 

 Tmesiphorus vernalis, and the female as T. JiPffperi. These two 

 were united under the former name in Part II, p. 102. The 

 genus, however, is without doubt Gtenistes, Pi. V., fig. 3a.

Gawler, South Australia, Mrs. J. Kreusler. 

 I have named this species of Gtenistes after the discoverer, 

 from whom I have received some very interesting additions to ray 

 collection of Pselaphidce. It differs very materially from G. 

 vernalis. It is much smaller, and the 8 — 10 joints of the 

 aiitcnnae gradually increase in size, while the 11th is nearly as 

 long as the three preceding. The penultimate joint of the max. 

 palpi is also more elongated than in the preceding species.
