CERICHKESTUS. 195 



THORAX transversus, ad basin plerumque transverse depressus. 



ELYTRA parallela, punctato-striata, plerumque tomentosa aut holo- 

 sericea. 



PEDES : tibiis posticis, a retro visis, longitudinaliter canaliculatis, Jiaud 

 calcaratis. 



Labrum transverse, sinuate. 



Mandibles concealed ; at their inner surface, near the base, sub- 

 dentate. 



Maxillary palpi (Tab. VIII. fig. 4 m) globose ; the basal joint 

 quadrate ; the second broader, and subdilated at the apex ; the third 

 subdilated, and sometimes obliquely truncate at the apex ; the third 

 twice the breadth of the second, and quadrate ; the fourth short and 

 flattened. 



Labial palpi (Tab. VIII. fig. 4%) elongate; the first and second 

 joints being subincrassated towards their apex ; the third elongate 

 and cylindrical. 



Antennas approximate, filiform, in some species subdilated, robust, 

 the length in the females being not more than two-thirds that in the 

 males ; the basal joint is produced, slightly dilated, and subinflected 

 outwards ; the third, fourth and fifth are shorter than the first, and 

 subequal. 



Eyes large and prominent, situated at the base of the head ; in the 

 males more globose than in the females. 



Head short, not produced in front, vertical. 



Thorax transverse ; the anterior angles considerably depressed ; 

 the sides parallel, not sinuate in outline ; the base is generally more 

 or less transversely depressed, and the surface for the most part 

 clothed with pubescence. 



Scutellum triangular, situated in the plane of the elytra. 



Elytra broader than the thorax, parallel, sometimes subcylindrical, 

 strongly punetate-striate, generally clothed with dark pubescence 

 more or less concealing the punctures of the strias ; the antemedial 

 surface is never depressed transversely. 



Legs : the anterior femora robust, cylindrical, subdilated towards 

 the middle. The tibice are short, inflected at their immediate base, 

 and gradually thickened towards the apex. The tarsi are short ; the 

 first joint triangular, not broader than the apex of the tibias ; the 

 second is of the same form, but somewhat smaller ; the third is 

 broader, more transverse, and distinctly bilobed; the fourth, pro- 

 ceeding from the base of the third, is produced and gradually thick- 

 ened towards the apex : the ultimate claw is bifid, and armed at its 

 inner surface near the base with a projecting spur or tooth, which is
