gato, 40 5oque subeequalibus, 6-9 sensim brevioribus, 10° transverso, 11° 
globoso-ovato. Prothorax fere transversus, convexus, lateraliter angu- 
latus, antice paulo productus, basi sinuatus, disco equatus. Elytra 
ovata, basi prothorace haud latiora, supra subplanata ; epipleure sub- 
angustate. Pedes graciles; tébie teretes; tarsi post. art. basali quam 
ultimus longiore. Prosternum postice curvatum. Mesosternum declive. 
The head of this curious insect has a marked resemblance to that 
of the hippopotamus. The eye is surmounted by a projecting orbit, 
which causes it to protrude in such a way as to give it the appearance 
of being almost pedicellate. Below the eyes the face is concave, 
and is particularly deeply excavated between the antennary orbits. 
The genus is related to Phligra. 
Ossiporis terrena. 
O, supra indumento terreno tecta, infra pedibusque squamulis albidis 
densissime vestita; antennis squamosis, articulis duobus terminalibus 
nigris. 
Hab. Natal. 
Covered above with an earthy crust, composed of flattish scales and

OnostEeRRuUS [ Pedinine ]. 
Affinis Pedino, sed oculi non divisi. Mentwm subcordiforme. Prothoraz 
margine laterali limbo replicato. Zvbie sensim latiores, haud trigonatz. 
Tarsi postici art. basali ceeteris simul sumptis fere aequali. Corpus valde 
. conyexum., 
The fold bordering the upper part of the edge of the prothorax is 
also characteristic of Trigonopus; but the fore tibie of that genus 
are even more triangular than those of Pedinus, and it also differs in 
most of the above characters. In its general appearance the species 
described below resembles Heliopathes Lusitanicus, but is larger and 
much more convex. 
Onosterrhus levis. 
O, niger, subnitidus; capite subtiliter punctato; prothorace elytrisque 
impunctatis. 
Hab. Western Australia. 
Black, slightly nitid; head finely punctured, concave anteriorly ; 
prothorax impunctate, much broader than the head, well-rounded at the 
sides, but a little incurved at the base, the posterior angle slightly pro-
