 prothorax rounded at the sides, the meso- and metathorax nar-

 margins raised ; behind obliquely truncate ; a deep strangulation 

 between the meso- and metathorax, the latter being elevated ; 

 the legs slightly pubescent. Abdomen globose, and covered with 

 pale golden -yellow pubescence ; the scale of the peduncle incras- 

 sate, its anterior face rounder or concave, flattened, and slightly 

 hollowed out behind.

This species constructs its nest on leaves, the texture of which 

 closely resembles that of many small species of Vespidae ; in 

 fact it is quite possible that it may take possession of a Vespi- 

 dious nest, and adapt it to its own purposes : the worker greatly 

 resembles in form that of the European species Formica lateralis.
