soldier are short, -with two stout angular teeth below the tip on the left 

 side, with one large one at the base on the left side. A stout cylindrical 

 spine stands out on either side of the front of the head. 



Glyptotermes hrevicornis, Froggatt. 



This is a species collected by Turner in the Mackay district, Queensland, 

 of a similar colour, but smaller than G. tuherculatus ; having small eyes 

 not standing out on the sides of the head, and 13-jointed antenna?. Tlie 

 wings short, slender, and about twice as long as broad. 



The soldier has a head twice as long as broad, rounded behind, but 

 straight upon the sides; pale rusty red at base, but much darker in front, 

 which is very rugose above the jaws; the latter short with three small 

 angular teeth on the left jaw, and two larger ones on the right. Length 

 under J of an inch, body elongate and cylindrical. The smaller worker 

 has the rounded head and prothorax pale yellow, with the body like that 

 of the soldier, only more hairy. 



Glyptotermes iridipennis , Froggatt. 



This is a dark brown termite, with clouded light reddish brown wings. 

 It measures i an inch to the tip of the wings, and ^ to the apex of 

 abdomen. The head is longer than broad, convex, and sloping down in 

 front; small ey^es ; 15-jointed antennae. The wings are very long, four 

 times that of the breadth, slender, and slightly pointed at the tips. The 

 type, which was mounted on card, comes from Frankston, Victoria ; I 

 have not seen any other specimens. 



Sub-family V. — Heterotermitin.e. 

 Differing from the last division in having the head longer than broad, 

 and the absence of ocelli. The costal and sub-costal nervurcs not in contact. 

 It contains a single genus, created for the reception of a very distinct 

 form from Kangaroo Island, South Australia. 



Genus I. — Ileterotennes, Froggatt. 



Besides the definitions in the sub-family, the head is nearly quadrate, 

 the eyes very small and not projecting; antenna? IG-jointed. Wings 

 nearly thrice as long as broad, with the scapular shield small and angular. 



Ileterotermes platycephalus, Froggatt. 



The type was received from Adelaide, and collected on Kangaroo 

 Island some years before. It is a very curious termite differing from all 

 known species in the almost square head and thick antenna?. In the 

 Macleay Museum there are four other specimens labelled South Australia. 



The general colour is dark chestnut brown ; the antennae barred with 

 lighter bands at the base of each segment ; the wings of a pale smoky 

 tint. It measures J an inch to the tip of the wings, and under ^ to the 

 apex of abdomen.
