in front of the eyes. The prothorax rounded on either side; long slender 

 dark-coloured wings, with the three parallel nervures running close to 

 each other, the second often merging into the front (costal) one in the 

 middle, but always free at the extremity, and the oblique nervures are 

 often composed of rows of dots.

angular teeth on each side. Head long, truncate in front. 



2. Glyptotermes tuherculatis. Soldier, antennae 15-jointed, a stout spine 



standing out in front on sides of head; two teeth on left-hand

4. Glyptotermes iridipennis. Winged form (only known), antenntc 



15-jointed; wings very long and slender. 



Glyptotermes eucalypti, Froggatt. 



This is the common species of the genus about Sydney, and is only found 

 by cutting off the outer rough bark of the Swamp Mahogany (Eucalyptus 

 rohusta). The termites, working through from the decaying centre of 

 the trunk, burrow through the living sap-wood and inner bark, into which 

 they gnaw narrow circular passages in all directions, so constricted that 

 one cannot pass the other and they must work independently. They live 

 in small communities, the bulk of which are workers or larval forms, 

 perhaps fifty in a colony, with very often only two or three soldiers among 

 them. The workers and soldiers are slender and cylindrical in form, 

 only differing outwardly in the shape and structure of the head, which 

 in the soldier is pale reddish yellow, with 14-jointed antennae; stout short 

 jaws turning over at the tips with three sharp angular teeth on either 

 side ; in the worker the head is spherical and of a pale yellow tint. 



The winged termite is chestnut brown, with semi-opaque slender wings 

 four times as long as broad. It measures to the tip of the wings under 

 ^ of an inch, and slightly over ^ to the apex of the body ; it is much 

 smaller in proportion to the workers and soldiers than any of the other 

 species. The eyes arc large, ocelli oval, the antennae 14-jointed, the 

 prothorax nearly as broad as the head, broader than long, and slightly 

 concave in front. 



Glyptotermes tuherculatus, Froggatt. 



This species comes from Uralla, New South Wales, where they were cut 

 out of a log ; I have not seen it from anywhere else. The winged termite 

 is of a general pale dull yellow colour, with transparent wings, and dark 

 nervures. It measures ^ an inch in length to the tip of the wings, and 

 just under ^ to the tip of the body. The soldier has the head bright 

 reddish brown, black jaws, prothorax ochreous, and the rest dull yellow. 

 It measures ^ of an inch, of a slender cylindrical form. The worker of 

 very similar shape except that the head is spherical. The jaws of the-
