 antennis pedihusque u(fis ; protliorace elonrjato, angulis anteriorihus 

 proininulis, dorso hiseriatim foHiter ininctato ; elytris longititdinaliter

Head short and broad, as broad as the thorax, above with a very deep, large, 

 irregular depression on each side, separating the eye and the portion of the head 

 behind it from the middle ; the broad middle part of the head is rather elevated 

 towards the vertex, and emarginate in the middle behind ; it is only very finely and 

 sparingly punctured. The thorax is very elongate, and is at the base as broad as 

 the elytra ; it is very slightly narrowed towards the front, but the narrowing does 

 not contiiuie quite to the front, and the front angles are rather sharply marked and 

 distinct : the upper surface is dull, and along th^ middle are two series of coarse 

 punctures, phiced each in an ill-defined impression and diverging a little towards the 

 front; the lateral margins are neatly defined, and just within each is a series of 

 puTictures. The elytra are elongate and narrow, and bear each four grooves in which 

 are placed coarse punctm-es, their hinder part is sinuate externally to facilitate the 

 movement of the hind femora, and outside the four grooves there is a line of punc- 

 tures on the broader basal portion ; on the uuder-surface there are coarse punctures 

 at the sides of the thorax and breast, and the ventral segments show some coarse 

 punctures or impressions, forming an obscure series at the base of each segment, the 

 apical segment is entirely covered with very coarse and deep, closely placed punctures. 

 The legs are stout, the femora being incrassate.

Tliougli this extremely remarkable insect should evidently be 

 classed near Bhizophkgus, it is so distinct therefrom that 1 have given 

 it a different generic name ; the following outline of its structural 

 characters will enable it to *be identified : — 



Antennae very short, 10-jointed, the Ist joint short and thick, the 2nd stout and 

 bead-like, 3—9 small, the 9th being very short and transverse, 10th joint forming a 

 large abi-upt club, the apical portion of which is pubescent, but not to be dis- 

 tinguished as a distinct joint. The parts of the mouth are but little visible, the 

 mandibles being scarcely, if at all, visible from the upper surface. The head is 

 abruptly constricted behind, so as to possess a broad neck ; on the undcr-surfaco 

 behind the eyes is a very deep large cavity, in which the club of the antenna can bo 

 received. Prothorax with the coxal cavities closed, and broadly separated from the 

 mcsothorax, and also rather widely separated from one another by a depressed space. 

 Metasternum elongate. Hind-body with five ventral segments separated from one 

 another by deep sutures, the basal one a good deal longer than the next ; it is curved 

 downwards towards the extremity, the pygidium is exposed, and shows a deep 

 longitudinal groove oii the middle. The tibia) are broad below the middle, but with 

 the apex very oblique ; they arc armed near the apex with teeth or small projections.
