 larger than the lower; 1 + 2, 2. Prosternal teeth small, strongly chitinized,

 but only moderately produced. All tergites strongly margined laterally, the 

 margins high, less strongly so caudally. Plates conspicuously roughened 

 with folds and tubercular elevations, the latter especially strongly developed 

 on the posterior plates. Each plate shows a strong median longitudinal fur-
