io4 LIFE STORIES OF AUSTRALIAN INSECTS. 



'Jumper" (Myrmccia albo-cinta) forms its nest un- 

 der the shelter of a low bush : it is a low mound 

 with an opening on the summit and another on the 

 side, level with the ground. When disturbed these 

 ants come running out like a pack of dogs, with a 

 series of short jumps, and attack everything they 

 meet" . . . M. forficata (the red and black bull- 

 dogs) live in rather large colonies up to 200 in 

 number, digging deep circular shafts or irregular 

 channels under logs ; when away from the latter 

 they form regular domed mounds over the nests 

 which in summer contain the large elongate, oval 

 brownish sacs containing the pupae, and often a 

 number of winged males and females. 



M. tarsata, or black bulldog ant, is found run- 

 ning up and down the larger tree trunks, and drops 

 to the ground at the slightest alarm ; when dis- 

 turbed in the nest, if the first two or three are 

 captured, the others retreat to their burrows and 

 do not show fight like others of the species." 



M, gnlosa is the red bulldog ant.. 



The *'Greenhead," Ectatomma metalUcnm is 

 common in grassy lands and gardens : it stings 

 very severely.
