lateribus clenticulatis aut creuulatis. Scutcllum quadratum 

 aut subquadratum, latitudine plerumqiie paiillo longior, 

 basi bilobatiim, disco la3vi, non carinato. Ehjtra thoracis 

 basi fere aaquilata, circa scutellum abrupte elevata, glabra, 

 confuse punctata; lateribus ante medium le^dter aut modicc 

 lobatis, limbo iuflexo pone medium attenuato, ante 

 apicem desinente. Pedes robusti; unguiculis basi iu- 

 crassatis. 



Prosternum subquadrato-oblongum, postice ampliatum, 

 margine postico obtuso aut obtuse rotundato; margine 

 antico plerumque paullo deflexo. 



Cadmus differs from Prionophura in the glabrous upper 

 surface of the body, in the smooth, non-carinate scutellum, 

 in the much narrower, inflexed limb of the elytra, and in 

 the rather more robust antennas of the male; both genera 

 agree in having the base of the pygydium covered to a 

 greater or lesser extent by the apices of the elytra. 



Cadmus australis, Boisd. ; litigiosus. Boh.; vihrans, 

 Suffr. ; excrementarius, Suffr. ; and trispilus, Chapuis, 

 belong to this genus. 



Genus Prionopleura, Saunders.

C. crucicolUs, Boisd. ; rugicollis, Gray ; cognatus, hi- 

 fasciatus, fiavicinctus and histrionicus, Suffi'., together 

 Avith purpurascens, Chapuis, form this generic group. 

 I also possess several undescribed species in my collection.
