ERIC MJÖBERG, ISOPTERA. 35 



large mushroom-shaped nests of the so-called »Kimberley- 

 typus» which were mentioned in 1897 by Saville Ke^t, 

 has hitherto remained unknown. It is about this nest that 

 EscHERisCH (Die Termiten öder weissen Ameisen, Leipzig 1909, 

 p. 83) writes the follovving: »Eine sehr meriiwiirdige Abart 

 der Hiigeltypus representieren Die Nester einer im Kimberley- 

 Distrikt (Nordaustralien) vorkommenden imbekannten Art, 

 welche Saville Kent als 'Kimberley-Typus' bezeichnet». 



In classifying the 12 different species I have made use of 

 the different characters of the soldiers. The number of joints 

 of the antennas seems to be a very reliable character. Aiso 

 the shape and colour of the head is a very constant charac- 

 ter. In most cases I have tried to illustrate the descrip- 

 tions with drawings taken from the microscope by a camera, 

 thus giving a true picture of the part in question. Thus a 

 large number of profiles of the head from the side and from 

 above of the new species, as well as of the two very little 

 known species, E. pyriformis Frogg. and E. magriiis Frog g., 

 are given.
