487 



partially abraded female specimen, the others appearing to be all 

 males. The impressions on the head cause four raised spaces to 

 appear on the disc, and a lobe behind each eye; of the discal 

 spaces the two front ones are about half the size of the two hind 

 ones, and all four are raised at their outer anterior edges. 



The second specimen, marked as having been " captured on 

 steps of Elizabeth Bay House, January 19th, 1864," differs in 

 being much smaller (8 x 2^ mm.), the head and prothorax densely 

 clothed with pale fawn-coloured scales, which entirely conceal the 

 derm and sculpture, and with stout darker scales appearing in 

 places; the antenna?, owing to the much denser clothing, appear 

 to be stouter and with shorter joints, the apical joints are finely 

 pubescent, the basal are supplied with stout scales; the elytra are 

 clothed as in the large specimen, but rather more regularly; on 

 both this and the two following specimens the scales of the under 

 surface are as in the large specimens, except that on the head 

 and prosternum they are somewhat denser and paler. 



The third specimen is much smaller and narrower (6x1^ mm ), 

 and has the head so densely clothed that the sculpture is entirely 

 hidden ; the scales moreover have a slight reddish tinge. 



The fourth specimen (6J x If mm.) appears (to the naked eye) 

 to be prettily variegated with black and white, and the derm is 

 considerably darker. The head, antennae and prothorax are 

 clothed as in the two preceding specimens, except that the 

 prevailing colour is sooty, the flanks of the head and prothorax 

 being of a very dingy white; elytra with sooty scales, and with 

 large irregular patches of whitish scales towards the sides, one 

 commencing at the shoulder and of- a zig-zag shape which termi- 

 nates beyond the middle, another almost fasciate near apex; the 

 apex itself and part of the extreme margin with whitish scales.

Prionoplus reticularis. White. 



Mr. Simson has shown me a living specimen of this fine New 

 Zealand longicorn which was given him as having come from a 

 window-sash made of kauri pine at Launceston (Tasmania).
