Biology. — Mr. Clark’s collections include specimens from 39

with other sjiecies. Thirty-five colonies were represented by soldiers 
and workers only, of which number 22 were associated with Ilami- 
termes obeimtis Silv., 10 with Eutennes occasus Silv., 2 with Eutermes 
apiocephakis Silv., and 1 with Calotermes obscurus (ITalker).
