B. Antennae 13-jointed. 

 (Text Fig. 10.) 



1, Left jaw with only three teeth. 



(Plate 1, Fig. 7, Text Fig. 9 a.) 5. C. affinis Mjöb. n. sp. 



2. Left jaw with more than three teeth. 



(Text Fig. 11b.) 6. C. trilineatus Mjöb. n. sp. 



All the six species seem to be limited in their distribution 

 to the rain-forests; five of them occur only in Northern 

 Queensland, only one {G. ajfinis Mjöb. n. sp.) in the south- 

 ern parts. They all build galleries and ducts in old rotten 

 logs or in branches on the ground. 



4. Calotermes malaiulensis n. sp. 



Imago (Text Fig. 4). Stout and robust, ferruginous, 

 underside yellowish, eyes and tips of jaws black, wings very 

 long, membrane as well as nervures ferruginous. 



Head slightly longer than broad, rounded, a little flat- 

 tened on the summit, transversally depressed in front before 

 tlie eyes; clypeus broad, rounded at the sides, dull white; 

 labrum slightly broader than long, convex, with a longitud-

 slightly emarginate at the anterior margin, rounded at the 

 sides, with a faint median line; sides showing an impressed 

 line following the börder and continuing round the anterior 

 angles to a distance about a third part of the anterior mar- 

 gin and there turning backwards, near the posterior margin 

 two small transverse impressions; meso- and metathorax 

 more lightly coloured, with a distinct dark, median suture. 

 Wings very long and darkly coloured, thickly reticulated with
