Tribe Taping mini (Emery) . 

 Azteca schimperi, Em., $ . 



" I have only once taken this species. It appears to infest 

 the belt of low-growing trees termed * Courida ' {Avice7i7iia 

 nitida), which fringe the seashore in British Guiana. In 

 this particular instance the ants were attending the coccid 

 Lecanium cequale, Green, which had infested several trees. 

 Formiearium unobserved." 



A. chartifex, For., subsp. laticeps, For., ^ . 



" A common species. Forms large carton nests on the 

 trunks of trees, and is especially fond of the mango for this 

 purpose. Some nests are as much as two feet in lengtii 

 This species inflicts a very sharp bite, and on the slightest 

 disturbance the ants swarm out to attack the intruder, 

 n)aking an audible rustling soiind. The nests may be 

 easily destroyed by fire, but a breeze is required to keep the 

 conflagration smouklering until the nest is entirely consumed. 

 Within six months, however, the ants will be found to have 

 made considerable progress in the construction of another 

 nest, frequently in the same spot."
