POSTSCRIPT. 
After this article had gone to press, the author was so fortunate as to 
obtain two other new species of Stethopathinz, even more remarkable than 
the ones described above. While collecting ants in the vicinity of Austin 
with Mr. A. L. Melander one afternoon during March, we found in a nest 
of Eciton opacithorax Emery a small insect which by its actions = at 
once recognized as a member of the Stethopathina. On carefully sifting 
the earth of the nest a second specimen was obtained. On comparing them 
we were exceedingly surprised to discover that not only were they different 
from any described Stethopathinz, but were also quite unlike each other. 
They are both females which I intend to describe in the near future as 
representatives of two new genera. From this it would seem that there 
must be a whole series of these peculiar Diptera living as true myrme 
cophiles in the nests of various ants.
