that m«ny luore will yet be taken, as all are extremely rare. Formi- 

 r'lrola was originally taken by the late Rev. R. L. Kinfr in nests of 

 i'ciiii poinititx atneopi/osii.s ; Mr. Foggatt has taken it in nests of tl.e same 

 ant, and I also have so taken it, but only one specimen, although 

 dozens of nests of that ant were specially examined for the beetle. 

 Mr. Davey has now taken eleven specimens of lonyipes in nests of 

 ErtdtonniKt iiirlall irit iii . and Mi. H. TT. D. (rriffith and I have taken 

 it in nests of the same species of ant at Port Lincoln. Recently I 

 obtained another species, cdaininiiKif, with that ant, and Mr. Hacker 

 has taken a specimen of (jUOira in company with it. Mr. Davey 

 took three of tuherruhtta in nests of Iridomyrmex rufoniyer. and 

 Mr. Gibbons one of epip/eural{f< with another species of Iridonnji m^x. 

 Mr. Goudie, Mr. Davey and I have each taken (carbo, (jKinukda and 

 pseudort'pbald respectively) a single specimen in nests of Fheidole. 

 Ihe hosts of the other species are not recorded, but, as will be seen, 

 the beetles occtir in the nests of at least four genera of ants, and 

 they probably occur with others. They have also been taken from 

 Atigust to January.
