filiform, defracted; mouth with large jd.yvs ; feelers 

 four^ unequal ; thorax uarrow behind, with a small up- 

 right scale between it and the abdomen, which is 

 nearly round ; females and neuters famished with a 

 concealed sting. Males and females winged, neuters 

 without wings. 



This genus of insects is proverbially industrious, and like 

 the two preceding genera, is composed of males, females, and 

 neutrals, they live together in large societies, and from the 

 depredations they commit in many of the warm countries, are 

 objects of considerable dread. They feed on animal and 

 Tegetable substances, and are particularly fond of sweets, 

 the larvce are without feet ; what are generally termed Ants 

 eggs, are the insects in the pupa state. 



10. Muiilla. Antennce filiform, in some species sickle- 

 shaped, fig. 36, plate 3; f/jorat? downy, retuse behind; 

 wings wanting in most species ; sfing concealed. 



These insects nearly resemble the Ants, living in a similar 

 manner, and nearly corresponding in general habits.
