situated between the lower margins of (not below) the eyes ; eyes 

 large, lateral, situated at the base of the head, and extending late- 

 rally nearly as far as the anterior angles of the thorax. 



Head short, transverse, inclined, but not abruptly, at right angles 

 to the plane of the elytra, impubescent. 



Thorax transverse, slightly broader than the head ; the anterior 

 angles are distinct and depressed ; the sides are marginate and sub- 

 constricted towards the base. 



Scutellum small, triangular. 



Elytra broad, robust, slightly rounded at the sides, the greatest 

 breadth being near the middle, punctate-striate, clothed throughout 

 with fine pubescence. 



Legs : the anterior femora robust (constricted at the base), broadly 

 truncate at the apex. The tibia} are abruptly inflected at the im- 

 mediate base, gradually thickened towards the apex. The tarsi are 

 short and sufficiently broad ; the first and second joints are trian- 

 gular, of equal breadth with the base of the tibia, the second joint 

 being rather smaller than the first ; the third joint is broader, sub- 

 circular, slightly bilobed, and fringed with a margin of thick rigid 

 pubescence ; the apical joint is longer than the third, narrow, and 

 inflected and gradually incrassated towards the apex: the claw is 

 bifid, and armed at its inner surface with a broad tooth. The poste- 

 rior femora are broadly dilated, gradually tapering towards the apex. 

 The tibia (Tab. V. fig. 2g) is short and robust, thickened towards the 

 apex ; immediately in front of the insertion of the tarsus, the margi- 

 nation of the posterior flattened side is produced into a distinct spur- 

 like projection ; the apex is obliquely truncate, and armed at its 

 extremity with a single incurved and strong tooth. The tarsus is 

 elongated and narrow, the basal joint being longer and somewhat 

 broader than the rest, triangular in form ; the second is of the same 

 form as the first ; the third is minute and almost circular ; from its 

 centre proceeds the insertion of the ultimate joint, which is narrow, 

 and produced into a globular inflation above the terminal claw. 



The single example from which I have formed this genus presents 

 abundantly distinguishing characteristics. The form of its maxil- 

 lary palpi (elongate and cylindrical, not dilated) separates it at once 

 from other subsequent genera, to which, in facies, it seems to be 

 related ; while the pecidiar form and hirsute antennae, and the spur 

 near the apex of the posterior tibia, as well as the relative lengths of 

 the joints of the tarsus (without any reference to its general facies), 

 forbid its being placed in any of the groups to which, by the form of 

 its palpi, it is most nearly allied.
