 lections of the Swedish State Museum). 



Of some of these 19 nest-building species our knowledge 

 is, however, very fragmentary; this is above all the case with 

 the interesting species Hamitermes rubriceps Frogg. (»nest 

 at the roots of a tussock of spinifex grass»). Also the 

 nests of many of the Eutermes-si)ec'ie8 are described in a 

 very inadequate way. Thence an attempt of tabulating 

 them is very difficult. In the sequel, however, I have 

 tried to draw up a preliminary key to the hitherto known 

 10 nests constructed by Eutermes-species. When no other 

 constant characters have been available I have had to use
