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 ai)pi'arance 

 of being almost pedicellate. Below the eyes the face is concave, 

 and is particularly deeply excavated between the antcnnary orbits. 

 The genus is related to Phligra. 



Ossiporis terreiia. 



O. supra indumento terreno tecta, infra pcdibusque squamulis albidis 

 densissime vestitaj autennis squamosis, articiUis duobus leruiinalibus

Hah. Natal. 



Covered above with an earthy crust, composed of flattish scales and 

 short projecting points; legs and body beneath entirely covered with a 

 uniform layer of fiat whitish scales ; lower part of the head and lip, and 

 antennae, clothed with loose whitish scales^ the two last joints of the 

 antennai black. Length 5^ lines. 



Onosterrhus [Pedininae]. 

 Affinis Pedino, sed oeuli non divisi. Mentwn subcordiforme. Prothorax 

 margine laterali limbo replicato. Tihice sensim latiores, baud trigonat<e. 

 Tarsi postici art. basali coeteris simul sumptis fere aequali. Corpus valde 

 convexum. 



The fold bordering the upper part of the edge of the prothorax is 

 also characteristic of Trigonopus ; but the fore tibia) 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 Lusitanicas, but is larger and 

 much more convex. 



Onosterrhus lav is. 

 O. niger, subnitidus ; capite subtiliter punctato ; protliorace elytrisque 



impimctatis. 

 Hah. Western Australia. 



Black, slightly nitid ; head finely punctured, concave anteriorly ; 

 prothorax imp unctate, much broader than the head, well-rounded at the 

 sides, but a little incurved at the base, the posterior angle slightly pro-
