542 AUSTRALIAN TERMITID.i^:, 



the jaws, with a curious Ijilobed pattern aljove the clypeus ; 

 antennie very slender, 18- to 20-jointed; clypeus large, convex, 

 rounded behind, with a deep median suture, a ferruginous spot 

 on eitlier side at the base of the antennae; labrum small. Prothorax 

 much smaller than the head, with a fine median suture running 

 from the base through the raeso- and metathorax ; abdomen oval, 

 swollen in the middle, broadly rounded at the tip. 



I/ab. : Kalgoorlie, W. A. (Mr. G. W. Froggatt; from nest); 

 Palm Creek, Central Australia (Prof. Spencer, Horn Expedition). 



Specimens of these termites were taken by my father in a dead 

 sheoak (Casuarina) stump towards the end of March; and at this 

 time the winged ones were more plentiful than the workers and 

 soldiers. In their habits and general appearance they resemble 

 Calotermes, and take the place of the eastern species, Jt. iriter- 

 medhis; l)Oth are plentiful in their districts. 



Rhinotermes intermedius, Brauer. 



Reise Novara, Zool. Th., ISTeuroptera, p. 49. 



Upper surface pale ochreous, lighter coloured at the base of 

 head and thoracic segments; under side, legs, and antennie pale 

 yellow; wings pale ferruginous, semitransparent, nervures darker. 

 Lengtli to tip of wings 7, to tip of body 4 lines. 



Head similar to that of R. reticulatus, but Avith the eyes much 

 larger and more prominent; ocelli larger. Antenn;x; very hairy, 

 20-jointed. Clypeus broader and not quite so convex. Prothorax 

 broader and more deeply concave in front behind the head. 

 Legs longer and tibiae more slender. Wings thrice as long as 

 broad, larger, and lighter coloured, but with the venation 

 identical. 



Soldiers and ivorkers as in the former species. 



This species is not very common about Sydney. I found one 

 small colony in the stem of a dead honeysuckle tree ( Bnnksia 

 serrata) near Sydney; but at Wallsend, near Newcastle, small 

 colonies under dead logs are common, gnawing irregular passages
