Head elliptical, much longer than broad, scarcely smaller than 

 the thorax. Antennie shorter than the head, probably 13-jointed. 

 Ocelli close to the ej^es. Jaws small, two-toothed, with dark 

 points. Prothorax with an indistinct suture in the centre, much 

 broader than long, concave anteriorly, sides convex, flattened 

 behind; l)ody scarcely longer than the thorax. Legs stout, with 

 the 4th joint of tarsi as long as the first three combined. Wings 

 23ale brown, costal and subcostal nervures ferruginous, with about 

 12 oblique branches; the other nervures very pale and indistinct, 

 with rows of finer ones between them, from the lower side about 

 12 oblique branches, the wings generally feeble and wrinkled. 



Soldifi)- greyish, hairy, shining. Lexigth 3 lines. Head oval, 

 reddish-3-ellow, flat on the summit, ferruginous in front, longer 

 and broader than the thorax ; jaws blackish, robust, almost 

 straight, bent in at the tips and armed with two broad teeth. 

 Antennje shorter than the head, the extremity of each segment 

 light coloured, shorter towards the tip. Prothorax twice as broad 

 as long, anterior angles concave, sides and posterior angles convex, 

 body club-shaped, broader and longer than the thorax, 3 lines in 

 length. 



Worker grey. Head small, with a pitch-coloured spot between 

 the antennae, the latter almost as long as the head; body almost 

 club-shaped, very much broader and longer than the thorax. 

 Length 3 lines. 



Hab. — Tasmania, and 8wan River, W.A. 



This description is taken from Hagen's Monograph. He says : 

 " In comparison w^ith the type, the somewhat larger Terines 

 ohscurus from Swan River (long. corp. '2^, exp. alar. 7 lines), is 

 not otherwise different from T. convexus. Between the claws is 

 seen a plantula. This species closely resembles Calotermes 

 improbu", and whether it should remain separate is a matter for 

 further consideration, though it is much smaller. The workers 

 and soldiers described by Walker (Brit. Mus. Cat. p. 52) as 

 belonging to Termes aiistrcdis, are very prol^ably those of C. 

 iiiiprobiis."
