OMOTOTUS. 209 



surface is rugose and deeply granulated, generally more or less im- 

 pubescent. 



Scutellum small, triangular. 



Elytra robust, short, distinctly broader than the thorax ; in most 

 species clothed with a thick and very fine pubescence, punctate-striate. 



Legs : the anterior sufficiently elongate. The femora are incurved, 

 attenuate at their base, and gradually thickened towards the apex. 

 The tibice are somewhat longer than the femora, straight, cylindrical, 

 inflected at their immediate base. The tarsi are short ; the first and 

 second joints being flat and broad, in form triangular ; the second 

 joint being somewhat smaller than the first ; the penultimate joint 

 is considerably broader than the second, and deeply bilobed; the 

 terminal joint is connected with the third at its base, and incurved ; 

 the apical claw is bifid, robust at the base. The posterior femora are 

 short and broadly incrassated. The tibice (Tab. VIII. fig. 8 Ji} are 

 short, incurved, and robust; the posterior surface is flattened and, 

 near the apex, longitudinally hollowed out into a groove terminating 

 in a socket for the reception of the tarsus; this groove is armed 

 laterally with short and frequent comb -like teeth ; immediately 

 above the insertion of the tarsus its margin is produced into a broad 

 and distinct tooth. The tarsi are short ; the two basal joints are 

 attenuate, the second being somewhat more minute than the first ; 

 the third joint is broader, subcircular, and somewhat longer than 

 the second ; the apical claw is entirely concealed from above by the 

 globular inflation of the ultimate joint. 



This genus is distinguished at once from Cerichrestus by its more 

 robust and broader form. The distinct pubescence on the elytra, 

 together with the form of the posterior tibiae (which are robust, in- 

 curved, and armed above the insertion of the tarsus with a distinct 

 spur), sufficiently separate it from other genera.
