Probably many minute species l^elonging to such genera as Bracliy- 

 myniic.v, Solcnopsis, StriDiiigciiys. etc., escaped detection owing to the 

 method of collecting. Among the specimens are three strikingly 

 myrmecoid Heteroptera and two myrmecoid Attid spiders. The col- 

 lection as a whole presents a vivid picture of the number and variety 

 of ants which in the tropics continually explore even the smallest 

 patch of foliage.

1. Ectatomma/ tuberculatum (Olivier). Fourteen workers.

workers.

5. Neoponera unidentata (Mayr). Three workers and four de- 



iilated females.

 soldiers.
