58 OUT OF DOORS. 



some of our rarest beetles are discovered. The colour 

 of the insect is bright but pale yellow, the larger 

 workers being brighter in hue than the smaller. 



Having already done as much mischief as could be 

 done, I had no scruple in removing the remainder of 

 the bark. To my astonishment, another ants' nest was 

 disclosed, but that of a different species, namely, the 

 Jet Ant (Formica fuliginosa). Thus we have the

When their house was thus broken open, the ants 

 showed at once the difference in disposition as well as 

 in form. The yellow ants ran about in a state of great 

 perturbation, and although they could do but little ap- 

 peared to do a great deal. They were very angry too,

 sun-beetle, grasped one of its antennae with a hold like

The jet ants displayed no such fussiness, but took 

 matters very coolly indeed. At first they seemed to be 

 surprised into something like activity, but they soon 

 appeared to make up their minds that there was no use 

 in troubling themselves more than necessary. So they
