the rostrum is also distinet; in the preceding species, if present, it is concealed except 
at the apex.

There is a single specimen, without a locality label, belonging to the Museum, 
that agrees with the description of this species, which is said to have “fronte distincte 
longitudinaliter plicata” and “elytris ... singulis pone medium plaga transversa alba 
fusco-marginata ornatis’”. Characters which render the species easy of identification. 
But there are also seven other speeimens, before me, that were taken at King 
Georges Sound by W. George Masters.” The type was recorded from Queensland. 
I think it very improbable that the species occurs in both places, and if the specimens 
before me are correetly identified (as I believe them to be) think it extremely pro- 
bable that Queensland was given in error”). 
The species is somewhat variable, as towards the base of the elytra there are 
sometimes spots of scales of the same colour as the conspicuous post-median spots; 
on the prothorax also there are sometimes feeble pale spots. The seulpture of the 
head is remarkable, and quite distinet before abrasion; there being either 11 or 
13 longitudinal carinae. The size ranges from 1'/, to 2 lines.
