Family FORMICIDtE. Formicldans. 



I consider the Heterogyna of Latreille as consisting of two races. 



1. The Philopona containing all those genera, that constitute Linne's genus 

 Formica, distinguished by their admirable industry, their wonderful economy, and 

 the nests they construct. 



2. The Misopona consisting of Linne's genus Mutilla, affording no such ex- 

 amples.
