This species was exceedingly abundant in certain localities. On 

 Malapaina, where trees were being felled, it occurred in such numbers 

 as to seriously interfere with collecting. Their nests had been 

 destroyed by the falling of the trees and the workers were very pug- 

 nacious. The larger workers are able to bite appreciably and, during 

 the several days that I spent collecting among the branches there 

 were few moments in which one or more were not biting me.

This is an arboreal species. The only colony that I found consisted 

 of about a dozen workers and a dealated female. It was beneath a 

 piece of loose bark on a recently felled tree. The workers move with 

 such rapidity that it is almost impossible to collect them without 

 injury.
