'' The formicary of tliis species was observed iti the nest 

 of the termite Entermes costaricensis, Holmgr. The termite 

 nest was situated on the stump o£ an old tree about four feet 

 from the ground, and was partly inhabited by termites and 

 partly by this species." 1913.

" This appears to be another uncommon species occurring 

 in the interior. Observed to feed on the honey-dew given 

 out by a Sassid nymph." 1914.

" A common species of ant throughout the colony. Small 

 nests are constructed by slightly drawing together the edges 

 of a leaf and covering the intervening space with a thin 

 covering of dark-coloured vegetable substance of paper-like 

 consistency, though somewhat more fragile. Any plant 

 whose leaves are suitable for this purpose is utilised by this 

 species as a dwelling-place. Coffee-trees (Liberian coffee), 

 if not properly pruned, are particularly liable to infestation. 

 The picking of the coffee is then rendered a difficult matter, 

 as the slightest disturbance causes the ants to sally forth and 

 attack the intruder by inflicting exceedingly sharp bites. 

 This species has been observed to feed on the honey-dew of 

 the coccid Pseudococcus citri, Risso, on cacao pods.''
