ERIC MJÖBERG, ISOPTERA. 61 



The species was found in the vicinity of Laura in the 

 Cape York Peninsula, in the open sun-bathed savannah forest 

 country. It builds very typical, flat and broad nests of the 

 shape and form as shown by Plate 3, Fig. i. It consists of a 

 very härd and about up to two inches thick earthy and sandy 

 substance as cover or coating and of rounded ducts and 

 galleries formed of a darker and more fragile apparently 

 partly wooden substance. It attains a height of up to one 

 meter and is about one meter in diameter at the base. A nest 

 of that size which I managed to bring home to Sweden and 

 which now is in the State Museum in Stockholm had a weight 

 of more than 500 kilogram in fresh condition. 



The top galleries, i. e. the hottest parts during the day, 

 of the nest of this species are to a great extent used as 

 cemeteries, a question which will be dealt with in a låter 

 chapter.
