Swan River, W.A. (Mr. A. M. Lea). 



This species is closely allied to punctipennis, but the antenna- 

 are longer, the prothorax is more cordate and the punctuation 

 on the elytra is much stronger. 



Genus R y t u s, King. 

 Trans. Ent. Soc. N.S.W. 1866, p. 303. 



This genus resembles much Gerallus, but the palpi arc \ ery 

 different: the last joint instead of being pedunculate at the base 

 and clavate at the apex is clavate at the base and thin and 

 slender (subulate) from the middle to the apex, which is generally 

 a trifle thicker, with a Aery small section on which is inserted an 

 exceedingly small and short membranaceous appendage. The g 

 has always the head more or less irregular and the penultimate 

 joint of the antennae longer. There is a good deal of confusion 

 in the synonymy on account of these sexual differences. The 

 species are found exclusively in Australia.

I do not know corniger, King, and the description of the head 

 is rather incomplete, but I am pretty certain that it is identical 

 with porcellus, Schfs. The head seems divided into two parts :
