This species has its nearest relatives in C. longiceps Frogg., 

 C. irregularis Frogg. and C. malandensis Mjöb. From the 

 first it is easily distinguished by the shape of the head, 

 the dentition of the jaws and the dimensions, from the 

 second by the shape of the head, the labrum, the jaws, 

 etc. and also the size, from the third by the longer and the 

 more parallel head, the jaws and many other characters. 



It is a typical inhabitant of the rain-forests or jungles. 

 I have found numerous workers, two soldiers and two wing- 

 less imagines in a rotten log at Cedar Creek, N. Queensland 

 (May). 



6. Calotermes (Neotermes) oculifer n. sp. 



Soldier (Plate 1, Fig. 3, Text Fig. 8). Body comparatively 

 short and stout, dull white, head rufous, jaws black. 



Head much longer than broad, with parallel sides slightly 

 emarginateat the hind-margin, shining, anterior angles obtuse, 

 posterior rounded, slightly impressed on the summit in the 

 centre and with a fairly deep median furrow in the front, 

 reaching backwards to the centre of the head; clypeus rect- 

 angular, short, its basal part not well marked; labrum short 

 and small, broadest at the base, rounded towards the tip, 

 its apical half bent down, and carrying a row of stiff 

 hairs; jaws curved at the outside, ridged on the upper side, 

 somewhat similar to those of C. malandensis Mjöb., but 

 smaller and the teeth different, the left with one rounded 

 tooth above the middle, another rounded smaller one be- 

 low, and a more rectangular one further dow^n, the third 

 situated just a little in front of the tip of the labrum, the 

 right with a very large, fairly sharp, triangulär, inwardly 

 directed tooth, and a more rounded one a bit further down, 

 corresponding to and situated at the same height as the third 

 tooth of the left jaw, tips crossing över each other near the 

 ends; antennae more than 15-jointed, basal joint broad and 

 stout, 2nd shorter, 3nd much longer, deeply rufous and 

 darker than the other joints, 4th only half as long as the 

 3rd, 5th and following gradually longer and slender; eyes
