On the Scaritidre of New Holland, 

 By William IMacLeay, Junr., Esq., M.L.A. 



3kd Paper. 

 [Eead 6th March, 1865.] 



On each of the two former occasions oa which I contributed a Paper 

 on the Scaritidd of New Holland, I believed that I had exhausted, 

 at all events for some time, the species of the genus Caremtm. 



In adding now twenty new species to that genus, I feel much 

 less certain of the completeness of my monograph than I did on 

 the occasion of my first Paper. 



As we receive collections from newly occupied portions of 

 this immense continent, and as we become better acquainted with 

 the Entomology of old localities, it becomes evident that we have 

 yet much to learn, both as regards the numbers and the habits of 

 this strictly Australian genus. 



But though species seem to abound, specimens are far from 

 numerous. It is rare, indeed, to find in the best collection, more 

 than five or six specimens, representing perhaps as many species, 

 and quite one-half of those which I have described are unique. 



Tliis extreme rarity may be accounted for, partly by the 

 limited range of some of the species, and to a still greater extent, 

 perhaps, by the difficulty of finding them owing to their deeply 

 subterranean habits. 



For some of the species described in this Paper, I am again 

 indebted to Mr. F. G. Waterhouse of South Australia, to whose 

 kindness I am also indebted for specimens of those previously 

 described by me, with notes of the localities in which they wei*e 

 found.
