from here to posterior margin of head which is rounded ; with long

Length of head : 0.65-0.70 mm.

A small but elongate and slender worker. Named in honor of Dr. 

 W. M. Mann, of the Bureau of Entomology, United States Depart- 

 ment of Agriculture, who has collected many species of termites in 

 the Tropics. It is unusual to base a species on a worker, but this 

 worker seems to be quite distinct, and a name is desirable to assign 

 the termitophiles which were found with this species. 



Type locality.— Lomb^vAm^ Spanish Honduras. Lombardia is 

 north and inland from Ceiba, which is on the coast. 



Described from a series of workers, collected at the type locality 

 by Dr. W. M. Mann, February-March, 1920, beneath deeply em- 

 bedded stone, termitophiles present.
