 ANTENNA robustce, sat magnce, apicem versus dilatatce. 

 CAPUT breve, verticale, thorac.e constrictius. 



THOKAX transversus, latus, rectangular is, angulis anticis exstantibus, 



depresses. 



ELTTKA lata, convexa, punctato-striata, colorata, glabra. 

 PEDES robusti; tibiis posticis simplicibus. 



Labrum subcircular. 



Mandibles robust at the base, and armed on the inner margin with 

 a short basal tooth, at the apex acuminated. 



Maxillary palpi (Tab. VII. fig. 2 m) robust, incrassated ; the basal 

 joint minute; the second dilated towards the apex and obliquely 

 truncate ; the third more robust and shorter, attenuated at the base ; 

 the ultimate joint abbreviated, conical. 



Labial palpi (Tab. VII. fig. 2n~) elongate, minute ; the basal joint 

 quadrate; the second somewhat thickened towards the apex, and 

 constricted at the base ; the third narrower at the base than the apex 

 of the second. 



Antennae approximate, situated between and below the inner mar- 

 gin of the eyes, robust, long, dilated at the apex ; the basal joint 

 elongate (extending, when placed laterally, beyond the sides of the 

 head) and gradually dilated, and inflected towards the apex; the 

 second ovate, short ; the third to the sixth nearly as long as the first, 

 more attenuate ; the seventh to the eleventh abbreviated, and more 

 robust, gradually incrassated as they approach the apex. 



Eyes large, subglobose, situated at the base of the head. 



Head short, not produced, much narrower than the thorax ; when 

 viewed laterally, depressed at right angles to the plane of the thorax. 



Thorax transverse, broad, rectangular; the anterior angles de- 

 pressed, but prominent ; the sides parallel and broadly marginate ; the 

 surface is flat, inclined at an angle of 45 degrees from the plane of 

 the elytra. 



Scutellum large, triangular, situated in the same plane as the elytra. 



Elytra broad and convex, considerably broader than the thorax, 

 rounded at the apex, punctate-striate, brightly coloured, glabrous. 



Legs : the anterior femora robust, and slightly incurved on their 

 inner margin near the apex. The tibice are short, robust, inflected
