xxu PROCEEDINGS OF THE 



Mr. Boyd exhibited a very remarkable Cerapterus, found 

 under a stone on the North Shore. The insect differed from 

 Arthroj)teo'us in the shortness and breadth of its elytra, and the 

 roundness of its thorax, and would probably be found to belong 

 to the subgenus Fhymatopterus of Westwood. 



1st JUNE, 1863. 

 William MacLeay, Esq., President, in the Chair. 



The President i-ead a Paper on the insects of Australia alHed 

 to the Glapliyridce, and exhibited specimens of the new genera 

 and species described in the Paper. 



The Secretary announced to the Members that an arrange- 

 ment had been made, by which the Monthly meetings of the 

 Society would henceforth be held in the School of Arts, Pitt 

 Street. 



The President said that he wished to take the eai'liest oppor- 

 tunity in his power of pointing out an error in Doubleday and 

 Westwood's Genera of Diurnal Lepidoptera, an error which 

 seemed to have been adopted in all subsequent Catalogues of 

 PapilionidcB. The Papilio Antinous of Australia, which is figured 

 in " Donovan's Insects of New Holland," from the unique speci- 

 men in the cabinet of W. S. MacLeay, Esq., of Elizabeth Bay, 

 is placed by Doubleday and Westwood as a synonym of Papilio 

 Turnus, a well known American Butterfly. He had not noticed 

 this circumstance until a few days ago, but he had then com- 

 pared the P. Turnus with the P. Antinous in Mr. MacLeay's 

 collection, and found, as he had expected, that there was not even 

 a resemblance between the species. 



The P. Antinous clearly belonged to the Podalirius group of 

 Papiliones, and would no doubt be found (as our acquaintance 

 with the Northern parts of Australia increased) to be, as originally 

 stated, a New Holland insect.
