singular resemblance to some forms of Trilohites, these protu- 

 berances appearing like the eyes of those crustaceans. They are 

 more prominent in some specimens than in others. 



PARNIDES. 



As far as we know at present this family is represented in our 

 Fauna by the genera Lidoclirus, (?) Elmis and Limnius, all of which 

 I have been so fortunate as to capture at Paramatta. Mr. 

 MacLeay has also found a species of the latter genus in a water- 

 course on the side of Mount Kembla, Illawarra. 



LuTOCHRUS. Erich. 



LUTOCHRUS AUSTRALIS. 



Breviter hirtus, fuscus ; capite punctate ; thorace minute punc- 

 tato, antice contracto lateribus sinuatis ; elytris punctis in 

 10 lineis dispositis notatis. 

 Long. 0-15 poll. PI. XIV. 



Paramatta River; on a floating stick. December, 1862. 

 Although I have placed the present species in this genus, 

 there are yet important differences which distinguish it from the 

 description given by Erichsen. The inner lobe of the maxillae 

 terminates in three corneous curved teeth or sets of teeth ; the 

 last joint of the palpi is sub-oval; and there are lateral ridges on 

 the underside of the thorax. In other particulars it appears to 

 agree with Lutoclirus. 



The insect is very slow in its movements, and appears to live 

 in little companies. All that I have taken were inhabiting the 

 same small floating stick. 



Elmis. Latr. 

 This genus is represented by at least five well defined species, 

 of which three are found at Paramatta. When the rivers in the 

 interior have been examined, there can be little doubt that many 

 new forms wiU be detected.
