1/4 HYMENOPTERA CHAP. 



Many of the Ponerides have elongate mandibles, but they are 

 inserted at the sides of the front of the head, not in the middle 

 of the front. These organs in some species of Odontomachi 

 serve as levers:, by aid of which the Insect can execute considerable 

 leaps. In only a few species are the males known ; Mayr and 

 Forel state that they are destitute of the peculiar mandibles 

 characteristic of the worker. 



The unique European representative of the Odontomachi, 

 Anochetus ghiliani, occurs in Andalusia. Near Tangier Mr. 

 George Lewis found it to be not uncommon ; but the sexes are 



not known, and it even appears doubt- 

 ful whether there exists any well- 

 , marked division between workers and 



female. Lewis observed, among the 

 ordinary forms, individuals with longer 

 bodies, usually one in a nest, and he 

 supposed these to be females ; Saun- 

 ders, on examining these examples, 

 found them to possess distinct ocelli, 

 and therefore agreed with Lewis as to 

 their being the female sex. Dr. Emery 



subsequently examined these same 



FIG. 77. Anochetus ghiliani, j i i ^ 



worker. Tangier specimens, and took what is scarcely 



a different view, viz. that they are not 



females but an intermediate form; and he also expressed the 

 opinion that " the true female may not exist." The male of 

 Anochetus is not known. The female of A. mayri, a Neotropical 

 .species, has rudimentary wings.
