This insect has entirely the facies of an ordinary Liparetrus, 
but presents some structural peculiarities which might almost 
warrant the bestowal on it of a new generic name. Its antennse 
having only seven joints will distinguish it specifically from all its 
hitherto described congeners, but the number of joints in the 
antennfe cannot be considered a generic character in the Austra- 
lian Heteronycidce ; the form of the anterior tibise (with the apical 
two external teeth very large and sharp, and a very small one 
above) and the very slight pilosity, are also exceptional. The 
distance from the apex of the elytra is very little less to the apex 
of the pygidium than to the base of the prothorax, so that a large 
piece of the propygidium is exposed, which (as also the pygidium) 
has no trace of a keel. The geminate stride of the elytra are 
fairly well-defined ; the puncturation of the interstices similar to 
that in the geminate striaj, but not quite evenly dispersed. The 
prothorax is slightly more than twice as wide as its length down 
the middle, its base very little wider than its front, its sides very 
strongly and suddenly dilated and rounded in the middle, its hind 
angles quite rounded off, its disc distinctly channelled.

COLYMBOMORPHA. 
There does not appear to me to be any sufficient reason for reject- 
ing this name (as Mr. Masters has done in liis Cat.). The structure 
of the claws and of the mesosternal process is very different from 
the same in Calonola. I can now add the information that the 
sexual characters are quite distinctive; I received, some time ago, 
a short series collected in Western Australia by E. INIeyrick, Esq., 
in which I find a single male (unknown to previous writers so far 
as I can ascertain). It has the antennal club very much longer 
than that of the female, and five-jointed.

The species of this genus are very similar in appearance inter se, 
and unfortunately their published descriiitions are not particularly
