The sjiecics is respectfully dedicated to K. W. Kmerson. 



Kightly, a study of this family should b,' basi'd iiiuui large series of reared sjiecimens, 

 since general collecting yields Init very few females. For this reason, a large uiimber of forms 

 htive been left un<lescril,ed. A most unsatistactory state of afl'airs. However, the family needs 

 intensive study over a eompartitively long period of time. All the species seem to be parasitic 

 upon the larva; or pupa; of ants.
