Dacnides. 



Tarsi with the 4th joint clearly visible, maxillary palpi with the 

 last joint cylindrical, or but little dilated; internal lobe of the maxilhe 

 simple. 



DAC1VE, La.tr. Prec. d. Car. Gen. 1796. (Type humeralis.) 



Tarsi distinctly 5-joiuted, 4th joint hardly smaller than the preced- 

 ing; eyes not very finely granulated, thorax margined at the base, 

 elytra with numerous rows of punctures arranged serially. 



This genus was established by Latreille in 1796, and called Engis 

 by Paykull in 1798, hence I have deemed it necessary to restore the 

 older name.
