530 AUSTRALIAN TERMITID^E, 



paratively slender, tibiae short and rather bent, with four stout 

 spines at the apex; tarsi long, claws stout, plantula small. 



Wings large, more than thrice as long as broad, rather pointed 

 towards the tips; fore and hind wings differing in the neui^ation : 

 scapular shield short, rounded, with the cross suture curving 

 round showing the base of the six branching nervures; costal 

 more robust than usual, receiving two stout parallel nervures 

 running out of the scapular shield and sloping up into it; sub- 

 costal sending out four other cross nervures sloping into the costal 

 beyond them, and a number of more transverse ones forming- 

 numerous short cells towards the tip of the wings; median nervure 

 running close to subcostal and connected with it at irregular 

 intervals by a number of transverse nervures most numerous 

 towards the apex; submedian running through the middle of the 

 wing, with six oblique short thick opaque nervures at base, and 

 five slender nervures branching out, turning downwards and 

 again dividing before reaching the margins; the whole wing thickly 

 reticulated with finer veinlets : hind wing with only one parallel 

 sloping nervure between the costal and sulx;ostal, but connected 

 to the costal with two very short oblique nervures as well as at 

 the tip; subcostal nervure running parallel and sending out three 

 oblique nervui'es running into the costal, and ending in a regular 

 network at the tip; there is no true median nervure, but a branch 

 emerging from the subcostal, in a line with the base of the 7th 

 oblique nervure of the submedian, takes its place and is connected 

 with short transverse nervures to the tip; the rest of the wing 

 as the fore wing. Abdomen elongate, oval, rounded at the tip, 

 with the anal appendices stout, but hidden when viewed from 

 above; cerci stout, conical. 



Hah. — Sans Souci, Sydney (Mr. J. L. Bruce). 



I have only one spirit specimen, but in perfect condition, taken 

 by Mr. Bruce in the house flying to the lamp. It is somewhat 

 like Calotermes insularis, White, in size and colour, but differs in 

 having the head convex and not flattened in front, the smaller 

 prothorax, neuration of wings and other important points.
