 2^ fasten us y but diflers in its s])incd ])rothorax S:c. Mi/strosa 

 has a quite different texture*.

Hah. "West Australia. 



SylUtus terminatus.

 nitidis ; prothoraco ante medium valdc constricto ; elytris miinis 

 elongatis, singulis costidis duabus discoidalibus in medio manifcste 

 magis scparatis ; apicibus fcmorum infuscatis ; abdominc infra,

 fumato. Long. 3| lin. 



Hah. Nicol Bay. 



These two species arc too distinct to be confounded with 

 any of the four previously described from Australia. 



Aphiorhynchus divisus.

 antennis nigris, articulis 3., 4., 5. basi subluteis, art. tcrtio quam

 nigris ; pedibus infuscatis, femoribus tibiisque anticis aurantiacis 

 exceptis. Long. 4 lin. 



Hah. Queensland (Rockhampton). 



* In reference to Apomte^-^, another genus of this subfamily, M. Lacor- 

 daire is certainly in error in assigning it a prothorax "strongly rounded " 

 at the posterior angles ; on the contrary, they are so produced, owing to 

 a slight reflection at the base, as to form, when viewed from above, a 

 distinctly acute outline. This is well shown by Mr, Robinson in the 

 tigure (Journ. of Entom. ii. pi. 16. fig. 6).
