in some species is smoother than in others and shows the punc- 
turation more conspicuously. In the present species the derm in 
the male example before me is very levigate and consequently 
the puncturation very distinct while in the female the derm is 
quite coriaceous and consequently the puncturation very obscure. 
This species differs from all its previously described congeners by 
its coloration, and also from chalybeus by the much greater width 
of the dilated side pieces of its clypeus; from cyanocephalus 
ceélestis and punctulatus by its much less strongly impressed 
elytral puncturation, from Laferte: by its less convex form, and 
from Australasia, bilunulatus, splendens, ovalis, and nummularis 
by the presence of fovez on the elytral epipleure.

depressum. 
O. obscurus, Blackb. This insect which I desevitiga as a var, ? 
of Australasie is a good species as I find that its elytral epipleuree 
have a small distinct fovea, which I overlooked when I was 
writing the description. 
LIPERNES. 
L. gibbosus, sp. nov. Late ovalis; valde convexus ; sat nitidus ; 
piceo-niger, vix neo-micans; pube cinerea sat dense 
vestitus ; subtiliter sat crebre punctulatus. Long., ,% 1. ; 
lat., <5 i (vix). 
Very close to L. subviridis, Blackb., but differing from it in 
the almost complete absence of an eeneous tone of color and in its 
much greater convexity, which is most noticeable if the insect 
be looked at from the side when the length of the elytra is seen 
to be not much greater than their height ; whereas in subviridis 
the length is not much less than twice the height.

L. creber, sp.nov. Late ovalis ; valde convexus ; minus nitidus ; 
piceo-niger ; pube cinerea sat dense epiatae ; crebre sat for- 
titer punctulatus. Long., 2 1.; lat., 31. 
Resembling LZ. gibbosws in ofl re wdc differs from its 
described congeners by its very small size and the close strong 
puncturation of its surface. 
N. Queensland ; taken by Mr. Koebele in the Cairns District.
