specie.s; I took several last December on tlie Angophora flowers at 

 Mossman's Bay. 



This is aQ easily recognised species, with its steely blue head 

 and thorax, and bright red elytra. 



RiiiNOTiA H^MOPTERA, Kirby, Trans. Linn. Soc. xii, p. 427, t. 22, 

 f. 7. 



Larva dull white, short, rounded, with large head, segments 

 narrow fringed with fine reddish hairs ; mouth parts ferruginous, 

 jaws black, small, at the tip of a smooth shining lobe, face 

 above smooth, shining, the upper portion projecting and forming 

 an over-arching ridge, which is finely striated ; first and second 

 thoracic segments broadest, abdominal segments of uniform size, 

 divided from each othei- by a fold at the apex of each preceding 

 one, which forms a triangular patch on either side, anal segment 

 broad, truncate, and shining. 



The chief food plant of the larva is Acacia suaveolens, but I 

 have also bred it out of A. puhescens and A. discolor. The eggs 

 are laid on the under side of the limb, where a small patch of bark 

 has been gnawed off by the beetle, a minute hole showing where 

 the larva has entered ; as it grows it hollows out the whole of the 

 stem, pupating in the upper end. At Rose Bay in May nearly 

 every bush of this Acacia contained one or more of the beetles or 

 their larvae. 



The beetle is a common one about Sydney, feeding chiefly on the 

 foliage of Acacia discolor, early in November. Its black head and 

 thorax, with deep brick-red elytra divided down the centre with a 

 narrow black stripe, and its elongated body easily distinguish it 

 from any other of the weevils. 



Chrysolophus spectabilis, Donovan, Epitom. Ins. N. Holl. 1805. 



Larva white, with shining ferruginous head, stout black jaws, 

 and rounded obese much wrinkled body ; above the head slightly 

 tinged with a ferruginous band; thoracic and abdominal segments 

 very much corrugated with many fine transverse furrows, so that 

 seen from above the divisions of the segments are very indistinct.
