SUPPLEMENT.

 [Bead 11th April, 1912.] 



Probably at no period in Australia has so much attention been 

 paid to insects, occurring in the nests of ants, as during the last 

 five years. The result has been that new and remarkable forms have 

 been obtained in abundance. But, as immense districts of Australia 

 have never been explored for insects of any kind, it is certain that 

 large numbers remain to be discovered, and prol)ably the numbers of 

 insects now known to occur in the nests of ants will be more than 

 f[uadrupled. 



The fact that I am now able to add eight new species of ('hUnnij- 

 dopsis, of which six were certainly taken since the paper of which 

 the present one is a supplement was read (July, 1910), is sufficiently 

 indicative of the perseverance with which these anomalous beetles 

 have been looked for. 



It is also a curious fact that (at any rate in the temperate parts of 

 Australia) the guests are more numerous in the cooler parts of the 

 year, and some completely disappear during the summer months, when 

 the ants themselves are more active. This fact may have something 

 to do with the paucity of specimens taken by collectors whose holidays 

 are usually of the briefest during the spring and autumn months.
