This species is variable in colour and in size, but in a series of specimeu.s from 

 any one locality these charaetei-s are fairly constant. The pronolum is sometimefs 

 smooth, and may be unicolorous oi' with faint indications of a transverse fascia; 

 sometimes it is piceous, with the anterior and jjosterior edges aiul a longitudijud, 

 median line of light colour ; in a few examples the posterior margin only is pale. 

 The base of the hemelytra is not always j^aler. Specimens from the Adelaide 

 plains are dark olivaceous-brown, with the orange marking on the head indistinct. 

 A single male from Queensland is fuscous with castaneous markings. Another 

 colour variety is castaneous above, with the iiemelytral markings extremely faint 

 or absent, and the sutures and outer margin of the clavus narrowly edged with 

 castaneous. 



In the' figures of the male palae, the large flattened claw is shown in various 

 positions: this claw is hinged in a nick at the apex of the tarsus, and when folded 

 back rests in a depression on the upper side of the joint. 



Life colours. In parts the colours of a freshly-killed s])ecimen rapidly alter 

 as the insect dries ; the life colouration of Adelaide specimens is as follows : 



S Head pale, with a large, brownish-orange, sub-circular marking, within 

 which are tAvo U-shaped, bluish-green markings; blackly suffused at base; face 

 cyaneous, paler centrally; eyes black. Pronotum, scutellum and henielytra as 

 previously described. Sternum pale, in parts greenish ; xyphus greep ; underside 

 of abdomen pitchy, paler posteriorly and on lateral edges; legs testaceous, in 

 parts diaphanous; posterior half of intermediate femora sometimes pale blue. 



$ Underside of abdomen bluish-green. 



The male is easily distinguishal)le by the pitchy abdomen.
