On the Scaritidce of New Holland, by 



William MacLeay, Esq., F.L.S. 



4th Paper. 



[Read 6th September, 1869.] 



It is now more than foui' year.s since I wrote my third paper on 

 the Scaritidce of New Holland, and during that period large 

 additions have, as I anticipated, been made to the list of species 

 received from various parts of Australia. I am desirous now of 

 adding to that list a few species which have come under my 

 notice since the date of my last publication, but before doing 

 so, I shall take the opportunity thus afforded me of making some 

 observations on the genera and species of the Family described 

 by Count de Castelnau, in the 1st volume of the Transactions of 

 the Royal Society of Victoria, and on the excellent little treatise 

 on the genus Carenum, by M. Le Baron de Chandoir, published a 

 few months ago in the Transactions of the Entomological Society 

 of Belgium. 



The first-named of these Entomologists has, in the above 

 cited work, described thirty-four new species of the Family, has 

 merged my genus E^iryscajphus in the genus Scaraj^hites, has 

 reconstituted the genus Eutoma of Newman, and has formed a 

 new genus under tJie name of Neocarenum. 



The reason assigned by Count Castelnau for the rejection of 

 the genus Euryscaiohus, is that the character on which I founded 

 its divison from Scaraphites, viz.,- some difference in the form of 

 the elj'^tra, is neither constant nor of generic importance. 



A reference, however, to my description of EuryscapJms 

 (Trans. Ent. Soc, N.S.W., vol. 1., page 187) will show that the 

 Count is mistaken in supposing that I formed the genus upon 

 any characters as distinct from ScarapMtes, though I certainly 

 point out the very different shape of the abdomen in the two 

 genera. It will be found that on the contrary I point out the 

 almost perfect identity in many respects of Euryscaphus with 

 Carenum. In fact, the E^iryscajthi are gigantic Oarenums, and are
