These insects are social, and as with other social 

 Hymenoptcra there are three forms, — males, females, 

 and workers. The males and females are winged ; the 

 workers are wingless. 



Take notes of the following points : — Different 

 forms of nests ; pairing of the sexes, and the shedding 

 of wings by the females ; metamorphoses ; duties of 

 the workers ; affection for young; slave-making spe- 

 cies; " -AWX.' scorns" (Aphides); Harvesting-ants;* the 

 Agricultural-ant, (17, VIII., 513); and ant-supporting 

 plants. (Pop. Sci. Review, Jan., 1875). (1, 179; 7,313, 

 206).
