gate; prothorax about as broad as the head, much broader 

 than long, fairly deeply emarginate in front, anterior angles 

 broadly rounded, sides tapering towards the base, posterior 

 margin slightly arcuate, light rufous, with two spöts near 

 the anterior margin, parts of the hind-margin and a slightly 

 bent cross-marking in front of it dark fuscous, median line 

 impressed; parts of the sides of meso- and meta thorax more 

 darkly coloured; thigs very thick and rounded, all tibiae 

 armed with three short and robust spines, hind tibiae longer 

 than the thighs, claws long and sharp. 



Measurements: Length of body 10—12 mm, length of 

 head with jaws 4,7 mm, length of head without jaws 2,8 

 mm, breadth of head 1,7 1 mm, length of prothorax 0,8 9 mm, 

 breadth of prothorax 1,5 2 mm, breadth of abdomen 2 mm. 



Queen. Very similar to the imago, only longer and 

 stouter, and * abdomen more extended. The chitinous plates 

 of the dorsal segments 2 — 6 of the abdomen are well marked, 

 having a lighter coloured spöt on each side. 



Measurements: Length of body 11 mm, length of head 

 1,61 mm, breadth of head 1,52 mm, length of prothorax 0,8 6 

 mm, breadth of prothorax 1,23 mm, breadth of abdomen 

 3 mm. 



This seems to be the first known queen of the Austra- 

 lian Calotermes-sipecies. In his work »Australian Termitidse», 

 Part II, where Froggatt describes 12 Australian speeies the 

 author says (p. 522): »I have never found a queen among 

 any community of the genus.» 



This speeies is apparently allied to C. trilineatus Mjöb. 

 and C. eucalypti Frogg. From the former it differs by its 

 larger size, longer and more darkly coloured head, the shape 

 of clypeus, the 14-jointed antennse etc. From the latter it 

 differs by having larger soldiers with longer and darker head, 

 well- marked apical part of clypeus (in C, eucalypti Frogg., 

 according to Froggatt, clypeus hidden!), the dentition of the 

 jaws etc. — A typical inhabitant of the rain-f orests ; speci- 

 mens taken at Herberton (January) and at Cedar Creek 

 (with unwinged imago and queen. April), N. Queensland. 

 It lives in rotten logs, forming irregular ducts and galleries.
