 old post " ; they were not found with the typical winged adult but 

 are probably the same species, since winged adults of only one species 

 of C oytotermes have been so far collected at Panama. 



Type locality. — Juan Mina, Canal Zone, Panama. 



Described from a large series of winged adults collected at the 

 type locality by H. F. Dietz, " V, 14, 1919," Dietz Ace. No. G. 546, 

 Hopk. U. S. No. 14174e; specimens of winged adults were also col- 

 lected at Panama City, Panama, and Ancon, Canal Zone.
