giving the tibiae the appearance of being crciiulated, are situated on the disc, tlie 

 space between them being smooth. 



Antennae pitchy, club greyish. 



?. Head produced in front; clypens slightly refle.xed ; a trideutate carina on 

 disc, with the centre tooth almost obsolete ; lateral margins slightly creunlate. 



Thorax not so coarsely pnuctured as in the cj; the lateral margins crenulated ; 

 the posterior portion and scntollary area thickly granulate ; on the disc of the 

 thoracic armature and truncation the granules have run together. The thoracic 

 armature is in the form of a sinnated slightly emargiuate carina, somewhat similar to 

 japetus ? , from which, however, it differs in the anteriorly rounded form of the head 

 and tridentate carina. 



Elytra dark castaneons ; striae punctured : interstices tiuely ])unctured with 

 small ^junctures; sides somewhat roughened and acicuhite. Lateral margins strongly 

 emarginate and margined ; between the humeral carina and tlie lateral margin are 

 three punctate striae ; interstices rugosely acicnlate. 



Pygidium shorter than in the S , and rather more thickly punctured. 



Underside similar to the S . Intermediate and posterior tibiae thickly punctured 

 on the np[ierside, and with the edges rather more thickly punctured on the under- 

 side than the S . 



Anterior tibiae without a tooth on the upperside of tlie a]iical tooth. 



Long. corp. S, ?, 47 mm. ; lat. 27 — 27i mm.

'Nea.T japetus King. S differs in having a short raised carina on the third 

 interstice, which is also more strongly curved, in the shape of the thoracic armature, 

 and in the shorter head and wider transverse carina. 



J. Black, shining, with the elytra obscure pitchy. 



Head rounded in front, with the clypeus slightly reflexed ; a central transverse 

 trijjointed carina extends acroSs the head, the centre point being the largest. The 

 lateral margins are strongly sinuate, the sinuation being strongest opposite the 

 transverse carina. 



Anterior jiortion finely rugosely reticulate ; posterior jjortiou much coarser. 

 Lateral margins fringed with reddish bristles. 



Thorax with the disc jiroduccd, and with eight distinct angles or jjoints, of 

 which four are situated on the discal carina, the front being rather j)roduced to an 

 obtuse angle which luis at each side an obtuse point, and then terminateil by a short 

 sharp point. Another carina then extends from near the centre portion of the trimca- 

 tion towards each side, and is furnished near the lower extremity with a sharp point. 

 The carina then extends in a semicircular form towards the lateral margins, but is 

 broken in the centre by a sharp curveil angle, whicli seems to divide the large curve 

 into two smaller curves. The frontal trnncatnre is very coarsely punctured in front, 

 the punctures being rather shallow and running into each other, the sides are very 

 dee])ly excavated and shining, very minutely punctured and finely alutaceous. 

 Sparingly punctured at the margins. 



Disc coarsely punctured with large ptmctnres on the anterior portion, which
