122 ON THE LIFE-HISTORIES OF AUSTRALIAN COLEOPTERA, 



It measures 13 lines in length ; underside, legs, head, centime of 

 thorax, a spot on either side above the eyes, the scutellum and 

 the marginal division of the vping cases black, the rest of thorax 

 and elytra ochreous-yellow. 



Paracephala cyaneipennis, Blackb., Trans. Roy. Soc. S.A. Vol. 

 xvii. pt. 1, p. 130. 



Larva slender, cylindrical ; mouth-parts black, head small, 

 thoracic segments broadest ; abdominal ones smooth, regularly 

 rounded, tapering towards the anal segment which terminates in 

 a small tubercle. 



In a short paper communicated to this Society in July, 1892, I 

 described three species of the genus Ethon whose larvae form galls 

 on native plants. The larva of this beetle belonging to an allied 

 genus also has the same remarkable habit. 



In June of last year I found a large number of the low shrubby 

 bushes of Casuarina distyla at the head of Rose Bay with the 

 branches covered with rounded gall-like excrescences about 7 lines 

 in diameter and 5 lines in height. On cutting some of them open 

 1 found the larvae placed at the base of the gall in a similar 

 manner to those of Ethon afflne on Pultenoia stipulai'is previously 

 described. 



The beetle is 4 lines in length ; head and thorax metallic dull 

 bronze, the latter irregularly corrugated ; elytra deep metallic 

 green, very finely and closely rugose ; legs and all the underside 

 dull metallic copper colour. I have never taken this beetle at 

 large, but have cut a great number out of mature galls, dozens of 

 galls being sometimes found upon one bush. 



A pate collaris, Boh. 



Larva white, showing a red line on the dorsal side bisecting the 

 lower abdominal segments ; broad and stout, with the apex of the 

 abdomen rounded ; jaws black, rather broad at the base, palpi 

 short, jointed, apical one large, oblong ; head small, thoracic 

 segments broad, legs small with very slender tarsi, fringed with
