Parramatta, common under stones in grass. 

 This species comes very near Tyrus laumeralis. The sculpture 

 of the head distinguishes it from the description given, as well as 

 the colour of the antennae, the ordinary size of the elytra, and the 

 great size of the second abdominal segment. There is an impor- 

 tant difference in the tibige of the forelegs ; those in T. humeralis 

 having a decided notch, (according to the figure) which does not 

 occur in any specimens of T. formosus. I am not sure that there 

 may not be even two species in this very common form.

Under wood and stone, in grass, Parramatta. 

 A very rare species. The length of its palpi, fig. 5. a. 

 (about frds. the length of the antennae), as well as the shape 

 of the last joint fwhich almost removes the species from this 

 genus) the deeply punctate surface of thorax and elytra, 

 and the absence of the usual stria on these latter organs at 

 once distinguish it.
