132 CURRENT NOTICES AND MEMORANDA. 



Those Ants without stings, with single nodes or scales, and 

 three ocelli, and whose larvae spin for themselves cocoons, are 

 called Formicidce; while those possessing stings, two nodes, and 

 whose workers want ocelli, and whose chrysalids are naked, are 

 called Myrmicidce. Of the FormicidcE, there are, including the 

 Madeira ant, Taphioma gracilescefis^ which I found at St. Mary 

 Aldermary Rectory, fourteen species; and of the Myrmiddce.y 

 including the Madeira ant, Pheidole Icevigata^ which I discovered 

 in the baker's shop in the Borough, seventeen species. 



There is a third nationality or family of the little people, the 

 Ponerid(E^ forming a connecting link between the FonnicidcE and 

 the Myr7nicid(E ; for while they have only one node — which is 

 raised to a level with the first ring of the abdomen, which latter is 

 always more or less constricted — they have their females and 

 workers furnished with stings, and the larvae spin for themselves 

 cocoons. These are represented by two rare species — the Ponera 

 contrada and Ponera pimdatissiina.
