116 ON THE LIFE-HISTORIES OF AUSTRALIAN COLEOPTERA, 



living flower stalks of the grass trees up to the end of December. 

 On these they gnaw little patches, and deposit their eggs in the 

 hole made for the next season's crop. 



The beetle is 11 lines to an inch in length, dark chocolate- 

 brown ; antennae fringed on the inner margin with short black- 

 hairs ; thorax very rugose, deeply punctured, and irregularly 

 marbled with patches of buff hairs ; the femora and tibiae and the 

 whole of the underside mottled with fine creamy hairs, a patch of 

 bright golden hairs on the tibise just above the tarsi; elytra deeply 

 and coarsely punctured, clothed with irregular patches of fine bufi" 

 and creamy hairs giving it a marbled appearance, the outer edges 

 of elytra fringed with creamy hairs, arcuate at the extreme tip of 

 each elytron forming a double toothed tip. 



Common about Sydney in early summer. 



XJracanthus Froggatti, Blackburn, P.L.S.N.S.W. ix., (2), 1894, 

 p. 106. 



Larva long, slender, reddish -yellow, with very short pointed 

 legs, and a slight fringe of scattered hairs round the head and 

 sides of segments ; mouth parts ferruginous ; jaws small, black ; 

 head longer than broad, forehead excavated in centre, a slightly 

 punctured projecting summit marked with fine parallel strise ; 

 thoracic and first five abdominal segments deeply and broadly con- 

 stricted, with a faint transverse furrow dividing each in the 

 centre, on either side of which is an oval rugose patch ; 6th 

 abdominal segment much longer than preceding ones ; 7th cylin- 

 drical, telescopic towards the 8th, the latter longer than the anal 

 segment, which is conical at the tip. 



The larva feeds upon the stems of Lasiopetalmn ferrugineum, a 

 low shrub common about Sydney, completely hollowing them for 

 a considerable length, and usually cutting the branch off before 

 pupating, and forming a chamber at the end of its burrow. 



Larvse were obtained, well grown, in infested twigs, in August, 

 at Rose Bay, and in the following April I found the beetles 

 emerging ; previously I had never found this fine longicorn.
