96 Notes on Australian Coleoptera. 
Pamborus Brisbanensis: length 11’; black with a green 
margin to the thorax and to the elytra; thorax broad, much 
wider behind than at its anterior part, with a lateral border 
forming a deep margin towards the posterior angles; it has 
a deep and longitudinal sulcate on the disc, and two short 
but deep ones on the posterior part; elytra with eight longi- 
tudinal and equal costz, between each of which is a line of 
elevated punctures. 
This insect has nearly the form of Guerini, and two speci- 
mens were found by Dr. Howitt near Brisbane ; one is, 
through his kindness, in my collection. 
Pamborus MacLeayi: length 10’; much shorter and broader 
than Alternans, and something of the form of Guerini; black, 
with the margin of the elytra of a dark green; thorax almost 
square, strongly marginated laterally, with the posterior 
angles broad and very protuberant; the impressions similar 
to those of A lternans, but the form very different, being much 
broader and wider in its posterior part; elytra shorter, but 
with costze and impressions like Alternans.

iver. 
LACORDAIRIA. 
The new genus I propose under this name is very remark- 
able, as presenting characters belonging to various groups ; 
the long-pending palpze show its affinity with Cychrus and 
Pamborus, but the anterior legs are strongly emarginated on 
their inner side, like those of many true Carabide, Brachy- 
nide, &c. It is evident to me that this insect ought to be 
placed between the last Cychride (Spheroderus) and Pam- 
borus, which, in my system, are all united in one family, but 
Mr. Lacordaire having divided it in two, it must be placed 
at the head of his Pamboride, in modifying the characters 
of that family, as far as the anterior legs are concerned; this 
genus has also a great affinity with Lestignathus, but is very 
distinct by the form of its palpi. Maxillary palpi very long, 
hanging down, with their second articles long, broad, inflated, 
particularly towards its extremity, third conical much shorter 
than the precedent, fourth very large, oval, dilated inside, 
pointed at its end, where it is hirsute. Labial palpi like the 
former, with their second article very long, the third short, 
and the terminal large, inflated and of an oval form, dilated 
inside, and pointed at its extremity ; it is hirsute. Labrum 
large, furcated ; mentum without a tooth ; antennz rather
