the right with three more or less triangulär teeth in the middle; 

 antennse 13-jointed, short, the last six joints slightly oblique 

 in the middle, being more prolonged at the interiör angle, the 

 3rd joint very short; prothorax much broader than long, 

 heart-shaped, emarginate at the front margin with impressed 

 median line, slightly arcuate in the middlo of the hind margin; 

 meso- and metatborax slightly broader, rounded at the sides; 

 legs of normal size, tibiae armed with three stout apical 

 spines, tips of claws darker; abdomen narrow, whitish. 



Measurements: Length of body 7,2 mm, length of 

 head with jaws 3,8 mm, length of head without jaws3mm, 

 breadth of head 1,7 5 mm, length of prothorax 1,8 7 mm, 

 breadth of prothorax 1,56 mm, breadth of abdomen 1,7 mm. 



This species comes close to C. eucalypti Frogg. and 

 C. hrevicornifi Frogg. From the former it differs (soldier) 

 by the form of the head, its well-marked apical part of 

 clypeus, the dentition of the right jaw, and its 13-jointed 

 antennse, from the latter by the much shorter head, the 

 coloration, etc. 



It is an inhabitant of the rainforests, where it lives in 

 rotten logs, forming irregular ducts and galleries. I have 

 taken specimens (no workers) at Cedar Creek (April) and 

 Malanda (January), Queensland, together with half-grown 

 imagines. 



In the galleries of this termite lives the new Cyphoderns 

 serratus Schött (see; Eesults of Dr E. Mjöberg's Swedish 

 Scientific Expeditions to Australia 1910—1913, 15, Collem- 

 bola, p. 52). 



9. Calotermes (Glyptotermes) dubius n. sp. 



Imago (wingless). General colour castaneous-piceous; 

 clypeus, labrum, palpi and antennse light rufous. 



Head small, rounded, broadest at the eyes, slightly 

 depressed on the summit, apical part of clypeus broad and 

 short, rounded at the sides, straight in front; labrum con- 

 siderably more narrow, with parallel sides, slightly rounded 

 at the tip, with a row of stiff hairs; jaws dark fuscous, the 

 left with a strong apical and three other smaller teeth.
