ZOOLOGY. 219 



filiform, dcfracted; mouth with large jaws ; /eeZerj 

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

 right scale between it and the abdomen, which is 

 nearly round; females and neuters furnished 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 comm-t'ln many of the warm countries, are 

 objects of considerable dread. They feed o.i animal and 

 vegetable substances, and are particularly fond of sweets, 

 the larvffi are without feet ; what are generally termed Ant^ 

 eggs, are the insects in the pupa state. 



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

 shaped, fig. 36, plate 3 ; thoi'ux downy, retuse behind ; 

 Tjsings wanting in most species ; sting concealed. 



These insects nearly resemble the Ants, living in a similar 

 jnanner, and nearly corresponding in general habits.
