200 YNGVE S.TÖSTEDT, MONOGRAPHIE DER TERMITEN AFRIKAS. 



braunen Fleck begrenzt, die ganze Basalpattie der Mandibel, die Seiten des Kopfes, Oberlippe, 

 Palpen und Fiihler hellgelblich ; Vorderrand des Prothorax in der Mitte ausgeschnitten. 



Totallänge 5, Breite des Kopfes bis 1,3 mm. 



fXach Havilands Typen!) 



Durch die zwei Formen von Nasuti, tyjiisch äbnliche Arbeiter u. s. w. steht diese Art E. geminatus 

 sehr nahe, ist aber sehr gut von ihm unterschieden. Aueh die Biologie ist sehr iibereinstimmend, indem diese 

 Art nach Havilaxd, wie E. geminatus, runde, auf der Erde stehende Högel bänt, in welelie sie zerschnittene 

 Grasstengel schleppt. 



Biologie. 



Baut nach Haviland auf der Erde stehende, runde Hugel, deren äusseren Zellen 

 mit zerschnittenem Gräs gefullt werden. 



Bevor noch die Soldaten dieser Art näher beschrieben worden waren, lieferte Mansel 

 Weale a. a. O. ii ber dieselbe folgende Notiz aus dem Kaplande: 



»In an account of the first living specimen of the South-American Ant-eater (Myr- 

 mecophaga jubata) in the Zoological Gardens, Professor Owen remarks, in the »Proceedings 

 of the Zoological Society», that attempts had been made to feed this animal with living 

 ants and their larvae, but that they appeared thoroughly distasteful to it, and he concluded 

 that these insects were refused on account of their secreting formic acid. During mv 

 recidence in the Cape Colony my attention was attracted to the soldiers of the commonest 

 species, Termes trinervius, on account of the apparently meaningless manner in which they 

 ran about, thrusting at every object with their lance-pointed heads. I often placed my finger 

 close to them, but never received any kind of wound, whereas most of the other kinds with 

 which I am acquainted bite severely. One day while watching them with a glass I no- 

 ticed a small ant come in contact with one, and it immediately seamed disabled. On 

 examining it I saw a gummy kind of liquid adhering to it, and accordingh- put a portion 

 of the nest and a number of Termites into a bottle for examination. On opening the 

 bottle I noticed a strong acid odour, and on testing it litmus paper was discoloured. 

 On examining the insect under the microscope I observed that the cephalic projection was 

 perforated at the extremity and communicated with a duct. On touching the same part 

 of living specimens a small dröp of acid and gummy matter was traceable on the finger. 

 Termes trinervius is the common food of the Cape Ant-bear [Orycteropus Capensis) and I 

 belive also of the Aardt-wolf (Proteles cristaius)-».
