Caput antice productum ; fronte lamellifera ; tuberibus 

 antenniferis validis, basi approximatis. Oculi supra 

 approximati, lobo inferiore mediocre. AntemicB valde 

 elongatee, simplices vel spinosge ; scapo crasso ; articu- 

 lis 3, 4, 5nodosis, brevioribus (4 multo breviori), 6-10 

 subeequaHbus, ultimo (c?) seepe longissimo. Pro- 

 thorax breviter ovatus, transversim rugatus, lateri- 

 bus inermis. Elytra ampla, elongata. Pedes elon- 

 gati ; femora sublinearia. Prosternura postice rotun- 

 datum. Mesosternum amplum. 

 M. Thomson, in proposing this genus, says that it is 

 perhaps near Pachydissus ; in the " Systema " Neoce- 

 ramhyx is confined to G. Paris, Wied., while most of the 

 species placed originally in the genus are in the second 

 work ranged under Pachydissus. M. Lacordaire adopts 

 this arrangement (see aiite, p. 508, n.) . I prefer following 

 M. Thomson's earliest idea, subject to the exclusion of 

 those species,* which he himself afterwards placed in 

 genera specially formed for their reception. Trirachys, 

 Hope, is near Neoceramhyx, but has a spined prothorax. 



* These were C auripennis, Pascoei, and nervosus.
