Nortuidae. 



The antennip of the insect'* of this large family are mostly simple : the bo<lies are thick, 

 stout and str'ntt ; their wings are of a moderate lenctb.and stnncthed by their nervures, 

 and their tonjiues are long. The wing.s, when not in u.v, are deflexitl upon their sid<-5,and 

 the botly is clothetl with scab^ rather than w<-«d or hair. The majority of the larvje of 

 the diffen-nt genera are naked, and have sixteen feet, though in some the .oecond ventral 

 pair, in otbepi thr first ventral pair, are wnntlne : they undergo transformation under 

 ground, and lorni ctcoons of Mlk in wlii«h particle* of sand are often glut d. 'Ihe uiolh
