I take great pleasure in dedicating this species to an outstand- 
ing American myrmecologist, Dr. M. R. Smith, of the National 
Museum. 
I am indebted to Dr. Smith for his kindness in comparing speci- 
mens of T. smithi with an undescribed species of Trachymyrmex 
from Lower California in his possession. 
The secretary of the Cambridge Entomological Club regrets 
to announce the death of Mr. Charles V. Blackburn at Stone-

ber of the Club for 41 years, having been elected at the 232nd

orary member.
