ERIC MJÖBERG, ISOPTERA. 21 



This species seems to be related to C. malandensis Mjöb. 

 but differs plainly by the considerably smaller size, the shape 

 and form of the head, the dentition of the jaws, the very 

 broad, emarginate prothorax, and the protruding hind angles 

 of meso- and metathorax. It is also characterized by the well- 

 developed dark rounded eyes. 



I have found two soldiers and a number of workers at 

 Cedar creek, N. Queensland (April). It forms simple ducts 

 and galleries in rotten logs. It is an inhabitant of the rain- 

 f orests or jungles.

 rounded, the apical one elongate; eyes large and slightly 

 prominent, coarsely faceted; ocelli oval, oblique, situated 

 near the inner margin of the eyes; prothorax as broad as 

 the head, broadly heart-shaped, slightly emarginate at the 

 anterior margin, anterior angles broadly rounded, sides flat- 

 tened and foUowed by an impressed line. which continues 

 round the anterior angles and to about a third part of the 

 anterior margin, where it suddenly turns backwards; meso-

 quite three times as long as broad, transparent, whitish when
