208 OMOTOTUS. 



clothed throughout with fine and almost obsolete fulvous pubescence. 

 Scutellum minute. Elytra parallel, robust, subcylindrical, short : 

 a very distinct transverse depression extends antemedially from the 

 suture to the sixth or seventh stria ; this depression gives an appear- 

 ance of prominence to the surface near the base ; punctures arranged 

 in the form of striae, which are large and distinct near the base, are 

 almost obsolete as they approach the apex : the surface is clothed 

 throughout very sparingly with fine long single bairs, and underneath 

 these with a very fine flavous pubescence. Antenna; robust, strongly 

 dilated ; in colour, the first to the third joints are ferrugineous, the 

 foxu'th to the eighth dark fuscous, the ninth to the eleventh flavous. 

 Legs fulvous throughout.

 Palpi maxillares breves, subdilatati. 

 Palpi labiales clongati. 



Antenn je fili 'formes, robustce, interdum ad apicem subtlliter incrassatce. 

 Caput breve, transversum, pcene vertieale, rugosmn. 

 Thobax transversus, aliquando subquadratus, interdum etiam ad latera 



obscure dentatus. 

 Elytra brevia, robusta, plerumque pube vestita. 

 Pedes: tibiis posticis longitudinal iter canaliculars et calcaratis. 



Maxillary palpi (Tab. YIII. fig. 8 m) short, robust; the first joint 

 minute ; the second broader, and gradually dilated towards the apex ; 

 the third short, and broader than the second (the breadth being equal 

 to the length) ; the terminal joint is broad, subglobose and flat. 



Labicd palpi (Tab. VIII. fig. 8 n) elongate, narrower than the 

 maxillary palpi ; the basal joint robust, the penultimate narrow and 

 cylindrical, the ultimate joint attenuate. 



Antenna; approximate, situated between the lower margins of the 

 eyes, robust, filiform ; the basal joint is dilated towards the apex ; 

 the second shorter and more minute. 



Eyes lateral, situate at the base of the head. 



Head short, transverse, depressed at almost right angles to the 

 plane of the thorax, hardly produced in front ; the surface is rugose, 

 and for the most part impubescent. 



TJiorax transverse, in some species almost quadrate ; the anterior 

 angles are for the most part distinct ; the sides are finely marginate 

 and subsinuate, or produced medially into an obsolete tooth ; the
