Oculi distantes, ad basin capitis, subglobosi. 



Caput breve, robustum, vix ad apicem produetwm, depressum. 



Thorax transversus, aliquando subquadratus, depressus. 



Elytra lata, robusta, pier unique punctato-striata et leviterpube vestita. 



Pedes: ant. tibiis ad basin incurvatis, ad apicem dilatatis et oblique 

 truncatis ; ant. tarsis brevibus, art. 2 ndo minuto ; femoribus pos- 

 ticis valde incrassatis ; tibiis longitudinaliter marginatis, et ante 

 apicem ecalcaratis. 



Labrum transverse, subrotundate at the margins. 



Maxillary palpi (Tab. IV. fig. 1 m) subelongate ; the basal joint 

 minute ; the second ovate, and broadly truncate at the apex ; the 

 third longer and broader than the second, and subcylindrieal ; the 

 apical joint is broadly conical. 



Labial palpi (Tab. IV. fig. 1 n) subelongate, narrower than, but of 

 the same form as, the maxillary. 



Antenna} robust, approximate, inserted below and somewhat be- 

 tween the lower margins of the eyes, more or less dilated medially ; 

 the first joint is incrassated, and slightly incurved outwards towards 

 the apex ; the second short and broad ; the third and fourth are sub- 

 equal, longer and narrower than the first ; the fifth is shorter than 

 the fourth ; the sixth to the eighth are shorter and generally more 

 robust ; the ninth to the eleventh are gradually attenuated towards 

 the extremity. 



Eyes tolerably large, situated at some little distance from the base 

 of the head and not extending laterally so far as the anterior angles 

 of the thorax. 



Head short, robust, narrower than the thorax, hardly elongated in 

 front, depressed at almost right angles to the plane of the elytra. 



Thorax transverse (in some species almost quadrate), broader than 

 the head, rectangular ; the sides marginate, narrower relatively than 

 in Thrasygoeus, Eupeges, and even Phylacticus ; the anterior angles are 

 more or less depressed, — its whole surface being inclined at a very 

 apparent angle to the plane of the elytra. 



Scutellum triangular, impunctate, generally impubescent. 



Elytra robust, more manifestly broader than the thorax than in 

 the subsequent genera, pimctate-striate, generally clothed with 

 pubescence, and depressed antemedially and obliquely, so as to give 

 an appearance of prominence to the scutellary surface. 



Legs: the anterior femora tolerably robust and subcylindrieal, 

 slightly incurved near the apex. The tibia (Tab. IV. fig. 1 c) is 

 abruptly incurved immediately at the base and gradually dilated 

 towards the apex, where it is broadly obliquely truncate. The tarsi
