The soldier of Syntermes inolestus is herewith described and fig- 

 ured for comparison with other species; the winged adult was 

 described in Burmeister in 1839.'' Silvestri in 1903 " described and 

 figured the soldier. 



Described from a single soldier from Cuyaba, Brazil, and deter- 

 mined by F. Silvestri as " Termes inolestus Burm " ; this specimen 

 with workers was presented to the United States National Museum by 

 Silvestri; this soldier (which was identified by Silvestri) has been 

 compared with a soldier collected with workers by Mann at Indepen- 

 dencia, Parahyba, Brazil ; this specimen is also now in the collection 

 of the United States National Museum. This soldier had a piece 

 of dead leaf or grass in its mandibles.
