Tliis is quite possibly the Termes nigriceps from western Mexico, 

 but as the type is lost and the description would fit at least two other 

 of our species, and doubtless there are more allied species in Mexico, 

 it is better to drop that name for the present. It is described by 

 Holmgren under E. nigriceps, but his nasuti are another form.
