Sub-family II. — Calotermitin.e. 

 The members of this group have robust wings, reddish brown in the 

 typical Calotermes, with the front parallel nervures connected by a 

 number of cross nervures, or veiulets forming a network of irregular cells. 

 The scapular shield has five or more nervures branching from the base, 

 and in some genera the neurations of the fore and hind pair of wing'4' 

 differ. ' ' 



A number of fossil forms have been described, for which new genera, 

 have been created, and other recent species found in the Old World and, 

 America are not represented in Australia. The genus Stoloter7nes is 

 included here, for though not found on the mainland, one species has been 

 described from Tasmania, and two from New Zealand. 



Genus I. — Calotermes, Hagen. 

 These termites do not construct regular nests, but live in small communi-' 

 ties in tree trunks or fallen logs, often not more than a hundred in a colony, 

 which consist chiefly of immature winged forms and workers; the soldiers 

 in some species are often very scarce, and form a very small unit in the 

 , nest. The perfect insects are usually of a light reddish brown, and are 

 easily recognised by the more complicated venation of the wings. The 

 soldiers have large heads, dark reddish brown, the jaws black; the latter 

 are thickened, stout and blunt, turned in at the tips, and the jaws are 

 irregularly toothed on the inner edge on the opposite sides. Seven species 

 are described from Australia, and one from New Zealand; others are 

 found in various parts of the world.
