ERIC MJÖBERG, ISOPTERA. 45 



The imago of Eutermes fumigatus Br. has 15-jointed, not 

 14-jointed antennöe as stated by Froggatt. 



In the very simple nest ot this species, consisting only 

 of some few irregular ducts and galleries, lived the very 

 peculiar Eucurtia paradoxa Mjöb. of the family Histeridce, 

 described and figured by the author in Ent. Tidskrift 1912, 

 p. 121 — 124, Taf. I.
