Mentum transversum, subintegrum. Palpi articulo ultimo ovato. Pro- 
thorax subquadratus, lateribus denticulatis. Zars? subdilatati, articulo 
primo majore. Corpus sublatum, planatum. 
Allied to Cucujus and Platisus. The first it strongly resembles in 
habit, but differs in the normal condition of the tarsi, the ovate 
terminal joint of the palpi, the head not prolonged behind the eyes, 
the mentum nearly entire anteriorly, and the broa/, rownded lobes 
of its deeply divided labium. From Platisus it differs in its robust 
habit, thicker antenne, the third joint of which scarcely exceeds 
the first in length, the narrower tarsi, not dilated at the sides, and 
the denticulate margins of the prothorax. 
Ipsaphes merosus. (PI. III. fig. 9.) 
I. piceo-niger, subnitidus, confertim punctatus; elytris singulis in medio 
obsolete bicostatis. 
Hab. New South Wales. 
Pitchy black, subnitid, especially the head and prothorax, finely and 
very closely punctured; head broadly obcordate, a deep transverse 
groove behind the eyes, the clypeus descending between the man- 
dibles and hiding the lip; antenne rather longer than the breadth of 
the prothorax, moniliform, the basal joint short, incrassated, the second 
short, the third scarcely longer than the first, the remainder shorter 
and subequal, the last ovate, pointed; eyes moderate, rounded; max- 
illary palpi with the terminal joint oblong-ovate, of the labial shortly 
ovate; maxillary lobes shortly ciliated at the extremity; mentum 
transverse, not produced anteriorly (the large transverse piece beneath 
this in the figure is the jugular plate) ; labium bilobed, the lobes broad, 
rounded; prothorax subquadrate, broader than long, rounded at the 
side, with four or five minute, distant teeth, the disk near the anterior 
angles slightly hollowed out; scutellum transverse, rounded behind ; 
elytra plane, strongly bent down at the sides, each having on its disk 
two nearly obsolete elevated lines in addition to the more strongly 
elevated line of the suture; body beneath and legs reddish pitchy, 
closely punctured. Length 7 lines.

Caput oblongo-subquadratum. Oculi prominuli, prothorace distantes. 
Antenne breves, subclavatee, articulo basali ovato incrassato. Mazille 
lobo interiore uncinato. urs? articulis tribus primis dilatatis, penul- 
timo minuto. Corpus elongatum, parallelum, planatum. 
A remarkably elongate and narrow form belonging to the sub- 
family Sylvanine as at present constituted, strongly illustrating the 
impropriety of separating Sylvanus from the Cucujidee, as has been 
done by M. Jacquelin du Val, and of the danger of coming to con-
