with which they repeated each twist and turn, must have been follow- 
ing odor trails. Several were carrying objects: a mite, an entomobryid 
collembolan, and two unidentified arthropod eggs. The mite and 
entomobryid were freshly killed and had evidently been captured as 
prey. This conjecture is supported by the fact that Erebomyrma 
workers were most densely concentrated at points where large numbers 
of entomobryids occurred. Later, in captivity, workers fed readily on 
a wide variety of larger moths and flies presented to them, but only 
after these had been killed and cut open. In the original nest over 
a hundred unidentified globular objects resembling arthropod eggs 
were found piled with the brood. These were cared for by the captive 
colony in the artificial nest and may have been used sporadically for 
food, although direct feeding was not observed. Similar structures 
were found by Eidmann ( 1936) in the nests of Erebomyrma eidmanni. 
Surinam. On March 14 a urichi colony was found in open, dry, 
second growth forest at Bernhardsdorp, near Lelydorp. It was nest- 
ing in a small rotting log partly buried in moist leaf litter in a well- 
shaded part of the forest. The population consisted of a single dealate 
queen, four soldiers, an estimated 500-1000 minor workers, and a large 
quantity of brood in every stage of development. Adjacent to the 
Erebomyrma colony was a large colony of the termite Armitermes 
minutus Emerson (det. A. E, Emerson). The Erebomyrma colony 
and a fraction of the Armitermes colony were placed alive in separate 
but interconnected artificial nests. Within a few hours after establish- 
ment Erebomyrma workers entered the still chaotic termite chamber 
and began carrying off eggs. They were unopposed by the much 
larger Armitermes adults, and in turn did not molest the Armitermes 
adults or nymphs. While the response of the Erebomyrma workers 
was clear-cut in this instance, it does not necessarily mean that the 
species is termitolestic on undisturbed Armitermes colonies in nature. 
The colony was kept alive for only a few days and there was no 
opportunity to extend the experiment. In this connection it is worth 
noting that Emerson (in Wheeler, 1936) found evidence that Solenop- 
sis (Diplorhoptru?n) laeviceps Mayr collects and stores eggs of 
Nasutitermes cavifrons (Holmgren) and N. costalis Holmgren in 
British Guiana. 
Behavior 
The Trinidad colony was kept under observation in an artificial 
nest for two months and notes taken on selected aspects of behavior. 
The ethology of this species is of considerable interest because nothing
