eyes, filiform, subincrassated towards the apex ; the first joint elon- 

 gate, dilated gradually towards the apex, and (when seen under a 

 high power) abruptly incurved and attenuated at the immediate base ; 

 the second joint is short, much narrower as well as shorter than the 

 first, constricted at the base and broadly truncate at the apex ; the 

 third, fourth and fifth are equal in length, longer than the second, 

 but shorter than the first, attenuate, but subdilated towards the 

 apex; the sixth is of the same form as, but more incrassated and 

 shorter than, the fifth ; the seventh to the tenth are shorter (the 

 length being hardly double the breadth), for the most part subdilated 

 and cylindrical ; the apical joint is somewhat narrower, and tapering 

 at the extremity. 



Eyes lateral, situated at the base of the head. 



Head (Front, fig. 6 s v) depressed at right angles to the plane of 

 the elytra, not produced in front, much narrower than the thorax. 



Thorax broad, transverse, rectangular, anteriorly not emarginate ; 

 the sides are depressed and marginate ; not constricted in front ; the 

 surface is generally irregularly tuberculated and granulated. 



Scutellum triangular. 



Elytra broader than the thorax, robust ; the shoulders being well 

 developed and prominent, more apparently so by reason of a more or 

 less distinct transverse antemedial depression ; punctate-striate, and 

 for the most part clothed with obsolete pubescence, the surface being 

 generally irregular both in sculpture and in colour of pubescence. 



Leys : the anterior femora robust, slightly attenuated near the 

 apex. The tibice are distinctly incurved at their immediate base, 

 straight, gradually and slightly thickened towards the apex. The 

 tarsi are short, the basal and second joints being subequal in size (the 

 basal being almost cordiform, the second triangular and equal in 

 breadth to the base of the tibia) ; the third is much broader, di- 

 stinctly bilobed, and fringed with a thick and rigid pubescence ; from 

 the base of the third proceeds the apical joint, attenuated and in- 

 curved, slightly dilated towards the extremity : the terminal claw 

 is bifid, armed at its inner surface near the base with an obsolete 

 tooth. The 'posterior femora are short, and when viewed from be- 

 neath, very robust, incrassated, the upper margin being almost cir- 

 cular, the lower margin almost straight, gradually attenuated towards 

 the apex. The tibia is short, abruptly inflected at the base, straight, 

 unarmed near the apex by any tooth-like spurs ; at the apex some- 

 what thickened and obliquely truncate ; the terminal socket which 

 receives the tarsus being fringed with a serrated margination of 

 closely- arranged comb-like teeth, and terminating ultimately below 

 the tarsus in a double curved claw. The tarsus is short and attcnu-
